Abstract: The first ever liverwort and hornwort checklist is provided for the Maluku Islands (Moluccas/Spice Islands) of Indonesia. We report 355 accepted and 16 doubtful species and reject 22 species previously reported for Maluku Islands. The list is based on the specimens housed in the Herbarium Bogoriense (BO) and reports from over 500 literature references, including monographs, regional studies, and molecular investigations. The Maluku Islands are part of the Wallacea Biodiversity Hotspot with many unique species found only in Wallacea. Publications focusing on liverworts and hornworts of Maluku Islands are few and scattered. Considering regionally widespread species that have been recorded elsewhere, we predict that further fieldwork exploring the diversity of habitats coupled with collections unveiled from regional herbaria, a number of new records remain to be reported.

Re-assessment of type material of Plagiothecium novae-seelandiae Broth. and descriptions of four new Plagiothecium taxa (Bryophyta, Plagiotheciaceae) from Australasia https://phytokeys.pensoft.net/article/114303/ PhytoKeys 238: 95-117

DOI: 10.3897/phytokeys.238.114303

Authors: Grzegorz J. Wolski, Mikołaj Latoszewski, D. Christine Cargill, William R. Buck

Abstract: A re-examination of the original collection of Plagiothecium novae-seelandiae described by Brotherus in 1916 indicated that this material is not homogeneous. Re-examination of the diagnosis of this species and morphological analysis supports that two separate taxa should be distinguished – Plagiothecium novae-seelandiae var. novae-seelandiae and P. novae-seelandiae var. brotheri var. nov. Also, comparisons with the original collection of Hypnum lamprostachys (= P. lamprostachys) showed differences, which supported their treatment as separate taxa. Revision of the genus Plagiothecium from Australasia (CANB, CHR, HO, MEL, WELT) and types of other species described from this part of the world (P. funale and P. lucidum) supported by the study of their diagnoses, qualitative and quantitative characteristics as well as mathematical analyses (PCA, HCA) allowed the division of the examined material into six separate groups – six separate taxa. Thereby, three distinct taxa are proposed – P. cordatum sp. nov., P. semimortuum sp. nov., and P. semimortuum var. macquariense var. nov. All taxa mentioned above are described in detail, their current known distribution and ecological preferences are also included. In addition, images illustrating their most important taxonomic features, as well as an original key to distinguish individual taxa are presented.

New taxa of Plagiothecium (Plagiotheciaceae) from Pakistan https://phytokeys.pensoft.net/article/109519/ PhytoKeys 236: 1-16

DOI: 10.3897/phytokeys.236.109519

Authors: Grzegorz J. Wolski, Aamir Shehzad Khan, Beata Paszko

Abstract: A revision of specimens of Plagiothecium deposited in the herbarium of Pakistan Museum of Natural History (PMNH) collected during a Japanese lead project on Cryptogams in the Western Himalaya (Pakistan) shows that the material consists of five taxa. Of the studied samples, the most common taxa were from the P. denticulatum complex, including Plagiothecium denticulatum var. obtusifolium, new to Pakistan. Examination of the rest of the collection showed that it consists of specimens with a unique combination of qualitative and quantitative characteristics of their gametophyte. For example, for small plants, with small asymmetrical, folded leaves, gradually tapering into long, acuminate, not denticulate apex, whose leaf cells are long and narrow, making the cell areolation tight, the name Plagiothecium filifolium is proposed. For other plants with large leaves, loosely arranged on the stem, concave, symmetrical to slightly asymmetrical, with denticulate apex and long decurrency composed of rectangular and spherical, inflated cells, the name Plagiothecium higuchii is proposed. However, within this material, specimens differ in terms of the length and width of the leaf cells and therefore, within this taxon, two varieties are distinguished: Plagiothecium higuchii var. higuchii and Plagiothecium higuchii var. brevicellum.

Bryophyte flora of Mount Tebu Forest Reserve, Terengganu, Peninsular Malaysia https://phytokeys.pensoft.net/article/105783/ PhytoKeys 234: 35-49

DOI: 10.3897/phytokeys.234.105783

Authors: Nur Saidatul Atiqah, Elizabeth Pesiu, Muhammad Syafiq Sarimi, Nor Aishah Shafie, Chin Wen Koid, Nik Norhazrina, Nur Syazwana, Gaik Ee Lee

Abstract: A checklist of the bryophyte flora of Mount Tebu Forest Reserve in Terengganu, Peninsular Malaysia, is presented. A total of 189 taxa in 71 genera and 26 families were enumerated. This figure represents 63% of the 298 bryophyte species recorded so far for the State of Terengganu. Out of 189 taxa of bryophytes, 26 liverworts are new additions to the bryoflora of Terengganu. The most prominent liverwort family is represented by Lejeuneaceae, with 54 species from 17 genera, while the moss family is the Sematophyllaceae, with 34 taxa in 13 genera. The majority of the species are epiphytes, either corticolous or ramicolous. Almost half of the bryophyte species have wider elevational ranges and occur from the lowlands to the summit of Mount Tebu.

Marsupella brasiliensis sp. nov. (Gymnomitriaceae, Marchantiophyta) from Brazil – the distribution of sect. Stolonicaulon in Neotropics is now confirmed https://phytokeys.pensoft.net/article/103975/ PhytoKeys 226: 65-77

DOI: 10.3897/phytokeys.226.103975

Authors: Vadim A. Bakalin, Yulia D. Maltseva, Alfons Schäfer-Verwimp, Seung Se Choi

Abstract: The specimen previously identified as Marsupella microphylla from Brazil is reassessed and described as a new species, M. brasiliensis. The new species is characterized by paroicous inflorescence, bispiral elaters, scale-like, commonly unlobed leaves and very small leaf cells. Descriptions and drawings are provided along with a corresponding discussion of the morphological peculiarity of the new species. Marsupella brasiliensis belongs to sect. Stolonicaulon, and the distribution of Marsupella sect. Stolonicaulon in the New World is confirmed. The infrageneric position of M. microphylla remains unresolved, and whether it belongs to the same section is still unclear.

Resurrection of Leucobryum scalare Müll.Hal. ex M.Fleisch. (Bryophyta, Leucobryaceae) based on phylogenetic and morphometric evidence https://phytokeys.pensoft.net/article/98990/ PhytoKeys 222: 27-47

DOI: 10.3897/phytokeys.222.98990

Authors: Patsakorn Tiwutanon, Kasidis Chaiyasut, H. Thorsten Lumbsch, Ekaphan Kraichak

Abstract: Leucobryum scalare was described in 1904 but its taxonomic status has been disputed, being reduced to a variety of Leucobryum aduncum or synonymized with Leucobryum aduncum. The taxonomic confusion of this taxon has remained unresolved. Hence, we revisited the taxonomic status of the taxon using phylogenetic and morphometric approaches. A total of 27 samples from Leucobryum aduncum var. aduncum and Leucobryum aduncum var. scalare were used to generate data from four markers, including ITS1, ITS2, atpB-rbcL spacer, and trnL-trnF. The concatenated dataset was used to reconstruct a phylogenetic tree. Both qualitative and quantitative morphological characters were measured and analyzed with Principal Component Analysis (PCA) and PERMANOVA. The results showed that the two taxa are closely related but they are reciprocally monophyletic. Both qualitative and quantitative characters could also separate Leucobryum aduncum var. scalare from Leucobryum aduncum var. aduncum as shown with PCA and PERMANOVA. We propose the resurrection of the species rank for Leucobryum scalare as separate from Leucobryum aduncum. This work highlights the need for a more thorough revision of Leucobryum to clarify the actual level of diversity in this genus.

Didymodon changbaiensis (Pottiaceae, Musci), a new species from Changbai Mountain, China and its phylogenetic position based on molecular data https://phytokeys.pensoft.net/article/96661/ PhytoKeys 221: 147-159

DOI: 10.3897/phytokeys.221.96661

Authors: Ting-Ting Wu, Chao Feng, Tao Bian, Guo-Li Zhang, Jin Kou, Hong-Xing Xiao

Abstract: Changbai Mountain, located in northeast China, is one of the areas with the most complete natural ecosystem preservation in China. A new species, Didymodon changbaiensis C.Feng, J.Kou, H.-X. Xiao & T.-T.Wu from north slope of Changbai Mountain in Jilin Province of China is described and illustrated. It is characterised by ovate or ovate-lanceolate leaves that are appressed when dry, acute leaf apex, lamina red or reddish-orange with KOH, unistratose lamina throughout, plane and unistratose leaf margins, percurrent costa with one layer of guide cells and without ventral stereids, upper and middle laminal cells with elliptical papillae over the transverse walls between two immediately adjacent cells and basal laminal cells not differentiated from the median cells. Our morphological analyses and molecular results, based on DNA sequences of ITS, rps4 and trnM-trnV, confirm that D. changbaiensis is revealed to be sister to D. daqingii J. Kou, R.H. Zander & C. Feng. This new species is compared with similar species and its phylogenetic position and ecology are discussed.

The systematic position of puzzling Sino-Himalayan Lophocolea sikkimensis (Lophocoleaceae, Marchantiophyta) is identified https://phytokeys.pensoft.net/article/84227/ PhytoKeys 206: 1-24

DOI: 10.3897/phytokeys.206.84227

Authors: Vadim A. Bakalin, Yulia D. Maltseva, Ksenia G. Klimova, Van Sinh Nguyen, Seung Se Choi, Aleksey V. Troitsky

Abstract: Lophocolea sikkimensis, a little-known Sino-Himalayan species, was collected in North Vietnam and its taxonomic position was identified by molecular genetic techniques. The species is characterized by generally narrowly pointed leaves, which are not seen in other representatives of Lophocoleaceae. We found that it belongs to the recently described genus Cryptolophocolea, although it is clearly morphologically dissimilar to other members of the genus. We propose a corresponding nomenclature combination: Cryptolophocolea sikkimensis comb. nov. This species is the only one in its genus with a predominantly Sino-Himalayan distribution; the vast majority of congeners are distributed in the Southern Hemisphere (mostly in Australasia). Reports of this species in Vietnam further confirm the close phytogeographic relationships of the flora of northern Indochina with those of the Sino-Himalayas and suggest that this species is found in other parts of the Hoang Lien Range and the southern Hengduan Range.

Reinstatement of species rank for Grimmia limprichtii (Bryophyta, Grimmiaceae) based on molecular and morphological data https://phytokeys.pensoft.net/article/82508/ PhytoKeys 204: 9-21

DOI: 10.3897/phytokeys.204.82508

Authors: Chao Feng, Jin Kou, Ting-Ting Wu, Guo-Li Zhang

Abstract: The genus Grimmia Hedw. has been considered taxonomically difficult because of its great morphological variability, and its treatments by different specialists have led to incongruent results. One of the debates in the genus is the species status of Grimmia limprichtii Kern, an Asian-European disjunct moss species that has been considered identical to Grimmia anodon Bruch & Schimp. or Grimmia tergestina Tomm ex Bruch & Schimp. It has also been regarded as the muticous-leaved male plants of G. tergestina. Based on a detailed analysis of the type and many non-type specimens combining the molecular and morphological data, the reinstatement of species rank for G. limprichtii is proposed. The diagnostic characteristics of G. limprichtii and its distinction from some closely related species, with which it may be confused, are discussed. Grimmia obtusifolia C. Gao & T. Cao is considered a synonym of G. limprichtii based on molecular and morphological data.

DOI: 10.3897/phytokeys.197.80531

Authors: Chao Feng, Guo-Li Zhang, Ting-Ting Wu, Jin Kou

Abstract: Inner Mongolia steppe is one of the suitable habitats for Didymodon species and a new species, Didymodon manhanensis C. Feng & J. Kou from Manhan Mountain in semi-arid region in Inner Mongolia, China is described and illustrated. It is characterised by leaves incurved and slightly twisted when dry, spreading when moist, narrowly lanceolate from an ovate base; subulate and fragile leaf apices; distally bistratose leaf margins that are recurved in proximal 2/3–3/4; excurrent costa with guide cells in 2–3 layers and without ventral stereids; smooth laminal cells and red KOH laminal colour reaction. Our morphological analyses and molecular results, based on DNA sequences of ITS, rps4 and trnM-trnV, confirm that D. manhanensis belongs to a group that includes D. obtusus J. Kou, X.-M. Shao & C. Feng and D. daqingii J. Kou, R.H. Zander & C. Feng. This new species is compared with similar species and its phylogenetic position and ecology are discussed.

Plagiothecium talbotii, a new species from the Aleutian Islands (Alaska, U.S.A.) https://phytokeys.pensoft.net/article/81652/ PhytoKeys 194: 63-73

DOI: 10.3897/phytokeys.194.81652

Authors: Grzegorz J. Wolski, Paulina Nowicka-Krawczyk, William R. Buck

Abstract: Plagiothecium talbotii sp. nov. is described from Attu Island, Alaska, U.S.A. The newly-described species is not similar in appearance to any Northern Hemisphere species; only the habit is similar to P. platyphyllum. However, it not only occupies a different habitat than that species, but genetically and morphologically, it is clearly distinct from it. The results of DNA sequencing, a detailed description of the morphological features, illustrations, ecological preferences and currently known geographical distribution of P. talbotii are presented. The most important distinguishing morphological features of this species are: the size of the plant; dimensions and symmetry of the leaves; dimensions of cells and their areolation; entire leaf apex; and long decurrencies with some inflated cells. Additionally, we propose to place P. talbotii in section Plagiothecium, which is confirmed by genetic analysis and morphological features.

Lectotypification, epitypification and history of the name Plagiothecium neglectum Mönk. (Plagiotheciaceae) https://phytokeys.pensoft.net/article/77839/ PhytoKeys 189: 1-8

DOI: 10.3897/phytokeys.189.77839

Authors: Grzegorz J. Wolski, Jarosław Proćków

Abstract: In the protologue of Plagiothecium neglectum, Mönkemeyer (1927) does not indicate any herbarium specimen as a type. The author only gave a short description and attached a figure illustrating selected features of this taxon. The original materials from the Mönkemeyer collection were deposited in the HBG herbarium; however, it is not currently possible to determine their location. Furthermore, one specimen of P. neglectum, currently known from the original Mönkemeyer collections, was found in the Herbarium B (B 30 0105646). The features given in the diagnosis of this taxon are consistent with those of the lectotype of Stereodon nemoralis Mitt.; only the leaf apex from Figure 207c (Mönkemeyer 1927) is different and thus suggests mixed material. According to Art. 9.1 of the Shenzhen Code, Figure 207c represents a holotype of P. neglectum. However, due to differences in the leaf apex and according to Art. 9.3 of the Shenzhen Code, the part representing the apex should be excluded from the holotype, and the remainder of Figure 207c is consequently designated as a lectotype of the name P. neglectum. However, because the lectotype does not include a complete set of significant distinguishing features, an epitype (B 30 0105646) was designated.

Studies in Austral Bryaceae (Bryopsida). III. A Preliminary Account with Keys to Rosulabryum J.R. Spence in Chile https://phytokeys.pensoft.net/article/70407/ PhytoKeys 185: 87-98

DOI: 10.3897/phytokeys.185.70407

Authors: John R. Spence

Abstract: A preliminary study of the genus Rosulabryum J.R. Spence in Chile is presented, with brief species descriptions, notes on ecology and distributions, and a taxonomic key. The following 12 species are confirmed with vouchered specimens; Rosulabryum andicola (Hook.) Ochyra, Rosulabryum billarderii (Schwägr.) J.R. Spence, Rosulabryum campylothecium (Taylor) J.R. Spence, Rosulabryum capillare (Hedw.) J.R. Spence, Rosulabryum coloratum (Müll. Hal.) J.R. Spence, Rosulabryum densifolium (Brid.) Ochyra, Rosulabryum longidens (Thér.) J.R. Spence, Rosulabryum macrophyllum (Cardot & Broth.) Ochyra, Rosulabryum perlimbatum (Cardot) Ochyra, Rosulabryum puconense (Herzog & Thér.) J.R. Spence, Rosulabryum rubens (Mitt.) J.R. Spence, and Rosulabryum torquescens (Bruch ex De Not.) J.R. Spence. Rosulabryum canariense (Brid.) Ochyra is tentatively excluded as the Chilean material can be referred to R. coloratum. Similarly, Rosulabryum viridescens (Welw. & Duby) Ochyra is tentatively excluded since the Chilean plants do not match the African type, but instead appear to be atypical plants of R. campylothecium.

Plagiothecium schofieldii, a new species from the Aleutian Islands (Alaska, USA) https://phytokeys.pensoft.net/article/69970/ PhytoKeys 184: 127-138

DOI: 10.3897/phytokeys.184.69970

Authors: Grzegorz J. Wolski, Paulina Nowicka-Krawczyk, William R. Buck

Abstract: Plagiothecium schofieldii sp. nov. is described from the Aleutian Islands, Alaska, U.S.A. Some morphological features of this species correspond to P. lamprostachys (Southern Hemisphere species); however, Plagiothecium schofieldii is genetically and morphologically different from this and other common Northern Hemisphere species e.g., P. denticulatum, P. platyphyllum, or P. ruthei. The most important distinguishing morphological features differentiating this species are: the arrangement of the leaves on the stem; dimensions, concavity and symmetry of the leaves; dimensions of cells and their areolation; orientation of capsules. Additionally, due to the strong concavity of the leaves, they are very often badly damaged under the microscope. We present the results of DNA research of the analyzed samples, and a detailed description of the morphological features. The new species is illustrated, and its ecological preferences and currently known geographical distribution are presented. Additionally, the authors propose to add this species to Plagiothecium section, which is confirmed by morphological features and genetic analysis.

DOI: 10.3897/phytokeys.180.65836

Authors: Ainun Nadhifah, Lars Söderström, Anders Hagborg, Eka Aditya Putri Iskandar, Ida Haerida, Matt von Konrat

Abstract: The first ever liverwort and hornwort checklist is provided for the Kepulauan Sunda Kecil (Lesser Sunda Islands) of Indonesia and Timor-Leste (East Timor). We report 129 accepted taxa, 12 doubtful taxa and three rejected taxa previously reported for the Lesser Sunda Islands. The list is based on over 130 literature references, including monographs, regional studies, and molecular investigations. It is clear that bryophytes from this region have been overlooked historically, and under collected, compared to seed plants, birds, and other organisms, forming a remarkable gap in the flora of Indonesia. Publications dealing with liverworts of Lesser Sunda Islands are few and scattered. We predict that further fieldwork, in addition to collections unveiled from regional herbaria, will uncover a number of new records that remain to be reported, especially considering that regionally widespread species have been recorded elsewhere.

Lectotypification of Plagiothecium mauiense, a Hawaiian synonym of Plagiothecium longisetum (Plagiotheciaceae) https://phytokeys.pensoft.net/article/64042/ PhytoKeys 177: 11-15

DOI: 10.3897/phytokeys.177.64042

Authors: Grzegorz J. Wolski, Jarosław Proćków

Abstract: In 2020, Plagiothecium mauiense Broth. was recognised as a synonym of P. longisetum Lindb.; however, due to the inability to compare all known original material, the conducted taxonomic analysis was not completed with lectotypification of the name. Syntypes of P. mauiense were found in four American herbaria: Harvard University Herbarium (FH00220142), Miami University Herbarium (MU 000000546), New York Botanical Garden Herbarium (NY01256708) and Yale University Herbarium (YU 233890). Considering the condition of the found material and Articles 9.3, 9.11 and 9.12 of the International Code of Nomenclature for algae, fungi and plants (Shenzhen Code) that is currently in force, a specimen NY01256708 was proposed to be the lectotype of P. mauiense.

Integrating continental mainland and islands in temperate East Asia: liverworts and hornworts of the Korean Peninsula https://phytokeys.pensoft.net/article/56874/ PhytoKeys 176: 131-226

DOI: 10.3897/phytokeys.176.56874

Authors: Seung Se Choi, Vadim Bakalin, Seung Jin Park

Abstract: The liverwort and hornwort flora of the Korean Peninsula possesses some unique traits arising from the geographic position of the Peninsula, where the mainland flora meets insular flora. This flora is still not exhaustively studied, due not only to political reasons, but also because much less attention has been paid than to adjacent lands by hepaticologists. A checklist presented is based on a study of ca. 15,500 specimens collected by the authors and a review of relevant literature. This study provides the checklist of liverworts and hornworts known from Korea and the geographical distribution of each species within the peninsula. The liverworts and hornworts in Korean flora include 346 taxa (326 species, 16 subspecies and four varieties) in 112 genera and 50 families. Since 2007, 75 taxa of liverworts and four taxa of hornworts are reported as new to the Korean Peninsula, with a number of the new records arising following application of new taxonomic concepts that have become apparent over the last few decades. While compiling the checklist, 42 species, previously reported to Korea, are excluded from the Korean liverwort flora.

Abstract: Octoblepharum peristomiruptum, a new species of moss in the family Octoblepharaceae from Panama and Brazil, is described and illustrated. The new species is characterised by plants with a reddish-purple colour particularly at the leaf bases, peristomes of eight teeth, each tooth composed of two rows of cells, fenestrate and usually completely separated at the base, strongly vertically striate-reticulate, some striations forked-like in shape. At the base of the teeth, some striations are horizontally orientated, poorly developed or absent, particularly on the cell wall that is rupturing in the separation of the vertical rows of the cells that form each tooth.

A new synonym from Hawaii and lectotypification of Plagiothecium longisetum (Plagiotheciaceae) https://phytokeys.pensoft.net/article/56612/ PhytoKeys 164: 21-31

DOI: 10.3897/phytokeys.164.56612

Authors: Grzegorz J. Wolski, Jarosław Proćków

Abstract: Plagiothecium mauiense was first described in 1927 by V.F. Brotherus, based on materials from Hawaii. It has, so far been, treated as a separate species. A detailed analysis of the original material housed in the New York Botanical Garden Herbarium (NY01256708) found the specimen to be characterised by a lack of metallic lustre; concave, asymmetrical, lanceolate to lanceolate-ovate leaves, shrunken in their dry condition; a straight, not denticulate, acute to apiculate apex; elongate-hexagonal cells in irregular transverse rows, 101–131 × 15–21 µm at mid-leaf; very lax areolation, with decurrencies composed of three rows of cells. These characteristics indicate that this species is identical to the original material of P. longisetum (e.g. H-SOL 1563 011; PC0132572). Hence, we propose that P. mauiense should be recognised as a new synonym of P. longisetum. In addition, a review of P. longisetum syntypes found one (H-SOL 1563 011) to have the same date of collection as the protologue, and to possess a quite abundant gametophyte turf with well-preserved sporophytes, indicating it to be fertile. Considering the above, we propose that specimen H-SOL 1563 011 be designated the lectotype of P. longisetum.

Lectotypification of the name Stereodon nemoralis Mitt. (Plagiotheciaceae), a basionym of Plagiothecium nemorale (Mitt.) A. Jaeger https://phytokeys.pensoft.net/article/51469/ PhytoKeys 155: 141-153

DOI: 10.3897/phytokeys.155.51469

Authors: Grzegorz J. Wolski, Anna Faltyn-Parzymska, Jarosław Proćków

Abstract: In 1859, William Mitten described Stereodon nemoralis (≡ Plagiothecium nemorale) based on the gathering of Sir J.D. Hooker from India. However, the protologue did not indicate any specific specimen or illustration. For the past 50 years, the original material (NY 913349) deposited at the NY Herbarium has been considered as the holotype. However, this assumption has since been found to be incorrect, because in the Herbarium of The Natural History Museum exists other original material of this species (BM 1030713), collected by Hooker. In addition, the specimen from NY Herbarium is in poor condition and its most important diagnostic characters are not visible. In contrast, the material from BM Herbarium is in very good condition, and therefore it is herein designated as the lectotype. Also, the paper describes the resolution of this type, a process complicated by changes that had occurred in the provisions of subsequent botanical Codes.

Welcome to the Czech Republic again! Rare northern mosses Calliergon megalophyllum and Drepanocladus sordidus (Amblystegiaceae) in South Bohemia in light of their European distribution and habitat preferences https://phytokeys.pensoft.net/article/51454/ PhytoKeys 154: 111-136

DOI: 10.3897/phytokeys.154.51454

Authors: Łukasz Krajewski, Lubomír Adamec, Marta Saługa, Halina Bednarek-Ochyra, Vítězslav Plášek

Abstract: Two aquatic moss species, Calliergon megalophyllum and Drepanocladus sordidus (Amblystegiaceae, Bryophyta), which had been considered extinct in the Czech Republic, were found in the Třeboň Basin, South Bohemia, in 2016–2017. They co-occurred in extensive reed- and sedge-dominated fen pools with humic water on the shore of an old fishpond and the former species was also discovered in a small humic pool in an old shallow sand-pit. The new Czech sites of these rare boreal species represent one of the southernmost known outposts within their entire European range. Previously, the two species were only known from single records in the Czech Republic from the late 19th and early 20th centuries. To confirm our morphological observations, we used phylogenetic analyses of DNA sequence variation in four chloroplast loci (atpB-rbcL, trnL-trnF, rpl16, trnG) and one nuclear region, the internal transcribed spacers of ribosomal DNA (ITS). We found (1) monophyly of all Calliergon megalophyllum specimens tested; (2) based on chloroplast DNA sequences, monophyly among all Drepanocladus sordidus specimens and representatives of Pseudocalliergon turgescens and P. lycopodioides moss species; (3) based on nuclear ITS sequences, monophyly of all original D. sordidus specimens. These results corroborate morphological studies and thus confirm the existence of natural sites for the studied moss species in the Třeboň Basin, South Bohemia, Czech Republic.

A study of community structure and beta diversity of epiphyllous liverwort assemblages in Sabah, Malaysian Borneo https://phytokeys.pensoft.net/article/53637/ PhytoKeys 153: 63-83

DOI: 10.3897/phytokeys.153.53637

Authors: Tamás Pócs, Gaik Ee Lee, János Podani, Elizabeth Pesiu, Judit Havasi, Hung Yung Tang, Andi Maryani A. Mustapeng, Monica Suleiman

Abstract: We evaluated the species richness and beta diversity of epiphyllous assemblages from three selected localities in Sabah, i.e. Mt. Silam in Sapagaya Forest Reserve, and Ulu Senagang and Mt. Alab in Crocker Range Park. A total of 98 species were found and a phytosociological survey was carried out based on the three study areas. A detailed statistical analysis including standard correlation and regression analyses, ordination of species and leaves using centered principal component analysis, and the SDR simplex method to evaluate the beta diversity, was conducted. Beta diversity is very high in the epiphyllous liverwort assemblages in Sabah, with species replacement as the major component of pattern formation and less pronounced richness difference. The community analysis of the epiphyllous communities in Sabah makes possible their detailed description and comparison with similar communities of other continents.

A review of Calypogeia (Marchantiophyta) in the eastern Sino-Himalaya and Meta-Himalaya based mostly on types https://phytokeys.pensoft.net/article/52920/ PhytoKeys 153: 111-154

DOI: 10.3897/phytokeys.153.52920

Authors: Vadim A. Bakalin, Ksenia G. Klimova, Van Sinh Nguyen

Abstract: The eastern part of the southern macroslope of the Himalayan Range, Hengduan Mountains and the complex of smaller ranges from Hengduan southward to northern Indochina is one of the taxonomic hotspots of Calypogeia in Asia and the world. Two main circumstances hamper the understanding of taxonomic diversity of the genus in this area: the absence of recent and detailed descriptions and identification keys and the necessity of studying fresh material with surviving oil bodies in leaf cells. This study resulted in 1) eleven species confirmed for this vast land, 2) seven more taxa recorded but likely based on identification mistakes and 3) fourteen more taxa that are not yet recorded but may be expected in the area. All these taxa are discussed, and most of them are illustrated and described based on the types; an identification key is provided. The occurrence of North Holarctic taxa is hardly probable in the Sino-Himalaya, whereas new records of taxa known from the southern half of the Japanese Archipelago, Taiwan and southeastern mainland China are possible.

Mosses of Gunung Senyum Recreational Forest, a tropical limestone forest in Pahang, Peninsular Malaysia https://phytokeys.pensoft.net/article/33860/ PhytoKeys 128: 57-72

DOI: 10.3897/phytokeys.128.33860

Authors: N. Norhazrina, N. Syazwana, M. Aisyah, H. Aznani, H. Maideen, M.S. Nizam

Abstract: Gunung Senyum Recreational Forest harbours 59 species, two subspecies and five varieties of mosses in 32 genera and 16 families that had been identified from a total of 589 specimens collected from the area. These figures represent 11.8% out of the 558 taxa, 20.2% out of the 158 genera and 34.7% out of the 46 families of mosses reported for Peninsular Malaysia. The total also represents 14.9% of the 442 taxa, 24.0% of the 133 genera and 40.0% of the 40 families of mosses recorded in Pahang. The largest family of mosses found in this limestone forest is Calymperaceae followed by Fissidentaceae. There are two new records for Pahang, Calymperes pallidum Mitt. and Taxithelium binsteadii Broth. & Dixon. The analysis of species similarities of mosses found in the study area with some other selected areas showed that Gunung Senyum Recreational Forest had a high percentage of species similarity with Perlis State Park at Wang Kelian, another limestone forest, at 38%. Corticol is the main habitat utilised by mosses in Gunung Senyum Recreational Forest with 47 taxa, followed by the lignicol and calcicol each with 35 and 26 taxa, respectively.

Abstract: This paper reports the mosses from Crocker Range Park (CRP) in Sabah, Malaysian Borneo. In total, 293 species, three subspecies and eight varieties belonging to 118 genera and 36 families are reported. This represents about 40% and 47% of the species and infra-specific taxa reported from Borneo and Sabah, respectively. Out of these, six species are new records for Borneo, namely Barbella horridula, Chaetomitrium lancifolium, Distichophyllum leiopogon, Rhaphidostichum luzonense, Rosulabryum capillare and Taxiphyllum taxirameum and 12 species and one variety are new to Sabah. With these additions, the current number of mosses in Sabah and Borneo are 651 and 766, respectively. The largest family of mosses is Calymperaceae with 35 species and one subspecies, followed by Sematophyllaceae with 32 species and two varieties and Pylaisiadelphaceae with 21 species and one variety. In conclusion, CRP has a very high species richness of mosses which is the second highest in Borneo, after Mount Kinabalu.

The mosses (Bryophyta) of Capitán Prat Province, Aisén Region, southern Chile https://phytokeys.pensoft.net/article/9181/ PhytoKeys 68: 91-116

DOI: 10.3897/phytokeys.68.9181

Authors: Juan Larraín

Abstract: The bryophytes of Capitán Prat province have remained one of the least explored in Chile. The eventual construction of several dams on the rivers Baker and Pascua required prospection of all groups of organisms including bryophytes, work that was facilitated by the recent construction of vehicular roads that now offer easy access to previously almost unaccessible locations. The results of intense bryophyte collecting during the austral summer of 2007 are here presented. A total of 260 moss taxa are reported for the province, corresponding to 256 species and four infraspecific taxa, of which 211 are new records for the province, 54 are new for Aisén Region, and two are new records for continental Chile (Pohlia longicollis (Hedw.) Lindb. and Rigodium toxarion var. robustum (Broth.) Zomlefer). Twelve species extend their known distribution ranges to the north, whereas 49 extend them to the south.

Abstract: A working checklist of accepted taxa worldwide is vital in achieving the goal of developing an online flora of all known plants by 2020 as part of the Global Strategy for Plant Conservation. We here present the first-ever worldwide checklist for liverworts (Marchantiophyta) and hornworts (Anthocerotophyta) that includes 7486 species in 398 genera representing 92 families from the two phyla. The checklist has far reaching implications and applications, including providing a valuable tool for taxonomists and systematists, analyzing phytogeographic and diversity patterns, aiding in the assessment of floristic and taxonomic knowledge, and identifying geographical gaps in our understanding of the global liverwort and hornwort flora. The checklist is derived from a working data set centralizing nomenclature, taxonomy and geography on a global scale. Prior to this effort a lack of centralization has been a major impediment for the study and analysis of species richness, conservation and systematic research at both regional and global scales. The success of this checklist, initiated in 2008, has been underpinned by its community approach involving taxonomic specialists working towards a consensus on taxonomy, nomenclature and distribution.

The resurrection of Neohattoria Kamim. (Jubulaceae, Marchantiophyta): a six decade systematic conflict resolved through a molecular perspective https://phytokeys.pensoft.net/article/4940/ PhytoKeys 50: 101-122

DOI: 10.3897/phytokeys.50.4940

Authors: Juan Larraín, Benjamin Carter, Blanka Shaw, Joern Hentschel, Lynika Strozier, Tatsuwo Furuki, Jochen Heinrichs, Barbara Crandall-Stotler, John Engel, Matt von Konrat

Abstract: The systematic placement of Frullania herzogii has been contentious since its description six decades ago. Over the years it has been interpreted as either a member of the genus Frullania or segregated into its own genus, Neohattoria, due to morphological similarities with both Frullania and Jubula. Here we provide molecular evidence that supports the recognition of the genus Neohattoria and its inclusion within the Jubulaceae, together with Jubula and Nipponolejeunea. Jubulaceae are placed sister to Lejeuneaceae rather than to the monogeneric Frullaniaceae.

A new species of Brevianthus (Brevianthaceae, Marchantiophyta) from New Caledonia with unusual underleaf production https://phytokeys.pensoft.net/article/4998/ PhytoKeys 50: 43-60

DOI: 10.3897/phytokeys.50.4998

Authors: Matt A.M. Renner, John J. Engel, Simon D.F. Patzak, Jochen Heinrichs

Abstract: Brevianthus is a distinctive genus of leafy liverwort in its succubously inserted, entire leaves, lack of underleaves, restriction of sexual organs to lateral-intercalary branches, scattered rhizoids and dense leaf-surface ornamentation. The sole species, Brevianthus flavus, is divided into two subspecies, one in Tasmania the other in New Zealand. A second species, Brevianthus hypocanthidium, is described as new and is the first record of the genus for New Caledonia. Among its distinguishing characters are its shallowly bilobed leaves, and triangular underleaves present on small to medium-sized shoot sectors, the lack of a hyaline leaf margin, and the crenulate leaf margin formed by heavily thickened external cell walls. The most unusual features of the new species are the presence of underleaves between lateral leaf insertion lines that reach the ventral stem mid-line, and the absence of underleaves from larger shoots. To explain these features we propose a competitive model of shoot formation wherein the ventral merophyte progressively loses vigor as its relative stature decreases, and its derivative cells become discontinuous and isolated along the ventral stem surface, with intervening areas occupied by derivatives of the more vigorous lateral merophytes.

Abstract: Lejeunea hodgsoniana Grolle ex R.J.Lewington, P.Beveridge & M.A.M.Renner sp. nov., A taxon originally recognised by Riclef Grolle in 1980, but not described, known from a number of coastal sites in the North Island, the northern extremity of the South Island, the Kermadec Islands, and the Chatham Islands of New Zealand, is described and illustrated. The species is distinctive amongst species of Lejeunea in the Australasian flora in the combination of complanate shoots, relatively large broadly-ovate leaf lobes, with some lobules bearing prominent multicellular triangular teeth on a base of two to four cells, the flattened perianthsa faint dorsal carina. Its publication brings the number of species recognized for New Zealand to 14, seven of which are currently considered endemic.

Integrative taxonomy resolves the cryptic and pseudo-cryptic Radula buccinifera complex (Porellales, Jungermanniopsida), including two reinstated and five new species https://phytokeys.pensoft.net/article/1487/ PhytoKeys 27: 1-113

DOI: 10.3897/phytokeys.27.5523

Authors: Matt Renner, Nicolas Devos, Jairo Patino, Elizabeth Brown, Andrew Orme, Michael Elgy, Trevor Wilson, Lindsey Gray, Matt von Konrat

Abstract: Molecular data from three chloroplast markers resolve individuals attributable to Radula buccinifera in six lineages belonging to two subgenera, indicating the species is polyphyletic as currently circumscribed. All lineages are morphologically diagnosable, but one pair exhibits such morphological overlap that they can be considered cryptic. Molecular and morphological data justify the re-instatement of a broadly circumscribed ecologically variable R. strangulata, of R. mittenii, and the description of five new species. Two species Radula mittenii Steph. and R. notabilis sp. nov. are endemic to the Wet Tropics Bioregion of north-east Queensland, suggesting high diversity and high endemism might characterise the bryoflora of this relatively isolated wet-tropical region. Radula demissa sp. nov. is endemic to southern temperate Australasia, and like R. strangulata occurs on both sides of the Tasman Sea. Radula imposita sp. nov. is a twig and leaf epiphyte found in association with waterways in New South Wales and Queensland. Another species, R. pugioniformis sp. nov., has been confused with Radula buccinifera but was not included in the molecular phylogeny. Morphological data suggest it may belong to subg. Odontoradula. Radula buccinifera is endemic to Australia including Western Australia and Tasmania, and to date is known from south of the Clarence River on the north coast of New South Wales. Nested within R. buccinifera is a morphologically distinct plant from Norfolk Island described as R. anisotoma sp. nov. Radula australiana is resolved as monophyletic, sister to a species occurring in east coast Australian rainforests, and nesting among the R.buccinifera lineages with strong support. The molecular phylogeny suggests several long-distance dispersal events may have occurred. These include two east-west dispersal events from New Zealand to Tasmania and south-east Australia in R. strangulata, one east-west dispersal event from Tasmania to Western Australia in R. buccinifera, and at least one west-east dispersal from Australia to New Zealand in R. australiana. Another west-east dispersal event from Australia to Norfolk Island may have led to the budding speciation of R. anisotoma. In contrast, Radula demissa is phylogeographically subdivided into strongly supported clades either side of the Tasman Sea, suggesting long distance dispersal is infrequent in this species.

Frullania knightbridgei, a new liverwort (Frullaniaceae, Marchantiophyta) species from the deep south of Aotearoa-New Zealand based on an integrated evidence-based approach https://phytokeys.pensoft.net/article/1404/ PhytoKeys 8: 13-36

DOI: 10.3897/phytokeys.8.2496

Authors: Matt von Konrat, Peter de Lange, Matthew Greif, Lynika Strozier, Jörn Hentschel, Jochen Heinrichs

Abstract: Frullania is a large and taxonomically complex genus. A new liverwort species, Frullania knightbridgei sp. nov. from southern New Zealand, is described and illustrated. The new species, and its placement in Frullania subg. Microfrullania, is based on an integrated evidence-based approach derived from morphology, ecology, experimental growth studies of plasticity, as well as sequence data. Diagnostic characters associated with the leaf and lobule cell-wall anatomy, oil bodies, and spore ultra-structure distinguish it from all other New Zealand species of Frullania. A critical comparison is also made between Frullania knightbridgei and morphologically allied species of botanical regions outside the New Zealand region and an artificial key is provided. The new species is similar to some forms of the widespread Australasian species, F. rostrata, but has unique characters associated with the lobule and oil bodies. Frullania knightbridgei is remarkably interesting in comparison with the majority of Frullania species, and indeed liverworts in general, in that it is at least partially halotolerant. Maximum parsimony and maximum likelihood analyses of nuclear ribosomal ITS2 and plastidic trnL-trnF sequences from purported related species confirms its independent taxonomic status and corroborates its placement within Frullania subg. Microfrullania.
