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.

Checklist of the grasses of India https://phytokeys.pensoft.net/article/38393/ PhytoKeys 163: 1-560

DOI: 10.3897/phytokeys.163.38393

Authors: Elizabeth A. Kellogg, J. Richard Abbott, Kamaljit S. Bawa, Kanchi N. Gandhi, B. R. Kailash, K. N. Ganeshaiah, Uttam Babu Shrestha, Peter Raven

Abstract: A checklist of the grasses of India is presented, as compiled from survey of all available literature. Of the twelve subfamilies of grasses, ten are represented in India. Most subfamilies have been examined by taxonomic experts for up-to-date nomenclature. The list includes 1506 species plus infraspecific taxa and presents information on types, synonyms, distribution within India, and habit. Twelve new combinations are made, viz. Arctopoa tibetica (Munro ex Stapf) Prob. var. aristulata (Stapf) E.A. Kellogg, comb. nov.; Chimonocalamus nagalandianus (H.B. Naithani) L.G. Clark, comb. nov.; Chionachne digitata (L.f.) E.A. Kellogg, comb. nov.; Chionachne wallichiana (Nees) E.A. Kellogg, comb. nov.; Dinebra polystachyos (R. Br.) E.A. Kellogg, comb. nov.; Moorochloa eruciformis (Sm.) Veldkamp var. divaricata (Basappa & Muniv.) E.A. Kellogg, comb. nov.; Phyllostachys nigra (Lodd. ex Lindl.) Munro var. puberula (Miq.) Kailash, comb. & stat. nov.; Tzveleviochloa schmidii (Hook. f.) E.A. Kellogg, comb. nov.; Urochloa lata (Schumach.) C.E. Hubb. var. pubescens (C.E. Hubb.) E.A. Kellogg, comb. nov.; Urochloa ramosa (L.) T.Q. Nguyen var. pubescens (Basappa & Muniy.) E.A. Kellogg, comb. nov.; Urochloa semiundulata (Hochst. ex A. Rich.) Ashalatha & V.J. Nair var. intermedia (Basappa & Muniy.) E.A. Kellogg, comb. nov.

How many type specimens can be stored in old lesser-known herbaria with turbulent histories? – A Juncus case study reveals their importance in taxonomy and biodiversity research https://phytokeys.pensoft.net/article/50735/ PhytoKeys 153: 85-110

DOI: 10.3897/phytokeys.153.50735

Authors: Jarosław Proćków, Anna Faltyn-Parzymska, Paweł Jarzembowski, Małgorzata Proćków, Anna Jakubska-Busse

Abstract: Many herbarium sets in Europe are still being catalogued and it is likely that many old-type collections are yet to be discovered. This research has the potential to facilitate the study of the biodiversity of many regions, especially regions for which collections are extremely scarce. This has been confirmed by a case study using Juncus (Juncaceae) examining the turbulent history of botanical collections at the WRSL herbarium and the evaluation of its importance to the study of taxonomy and biodiversity since 1821. The analysis revealed that the WRSL collection is rich in types (ca. 3.6%) and we identified 76 (of 78) new, historically and nomenclaturally important specimens (types, original material and so-called “topotypes”). Some of these type specimens represent duplicates of these that were stored in Berlin and destroyed during World War II. Many of the type specimens are from the United States of America, South Africa, India, and Canada. The largest number of Juncus type specimens stored at WRSL originate from South Africa (42.3% of all type specimens), even though Juncus is rare in Africa. Our study highlights that uncatalogued old collections that are under-explored and under-exploited have the potential to facilitate the discovery of specimens important for the study of biodiversity, conservation, taxonomy and nomenclature.

Rhizophora mucronata var. alokii – a new variety of mangrove species from the Andaman and Nicobar Islands, India (Rhizophoraceae) https://phytokeys.pensoft.net/article/5037/ PhytoKeys 52: 95-103

DOI: 10.3897/phytokeys.52.5037

Authors: P. Ragavan, P.M. Mohan, R.S.C. Jayaraj, K. Ravichandran, S. Saravanan

Abstract: Rhizophora mucronata var. alokii (Rhizophoraceae), a new variety of Rhizophora from the Andaman and Nicobar Islands, India, is described and illustrated. The new variety is remarkable in having four stamens, laterally folded leaves, a short peduncle, thick leathery petals, and a four-sided ovary with a sessile style. A key for the species of Rhizophora of the Andaman and Nicobar Islands is also provided.

Eriocaulon madayiparense (Eriocaulaceae) – A new species from the foot hills of the Western Ghats of India https://phytokeys.pensoft.net/article/1410/ PhytoKeys 10: 19-23

DOI: 10.3897/phytokeys.10.2297

Authors: M.M. Swapna, KP Rajesh, C.N. Manju, R. Prakashkumar

Abstract: Eriocaulon madayiparense Swapna, Rajesh, Manju & Prakashkumar, sp. nov. is described and illustrated from the Madayipara, a lateritic hillock in the midland of Kannur District of Kerala. The species is allied to E. eurypeplon Koernicke, in its two free male and female sepals, female sepals being keeled and acute and not exceeding the floral bracts, acuminate leaf apex and setiform seed appendages appearing in vertical rows, but differs mainly inyellow seeds with solitary appendage arising from transverse radial walls, curved and connate with the adjacent ones of the same vertical row forming longitudinal parallel ribs on the surface of the seeds.

Larsenianthus, a new Asian genus of Gingers (Zingiberaceae) with four species https://phytokeys.pensoft.net/article/1357/ PhytoKeys 1: 15-32

DOI: 10.3897/phytokeys.1.658

Authors: W. John Kress, John Mood, Mamiyil Sabu, Linda Prince, Santanu Dey, Edakkandiyil Sanoj

Abstract: Larsenianthus W.J.Kress & Mood, gen. nov. is described with one new combination and three new species. Larsenianthus careyanus (Benth.) W.J.Kress & Mood, comb. nov., is widespread in India and present-day Bangladesh; L. wardianus W.J.Kress, Thet Htun & Bordelon, sp. nov., is from upper Myanmar in Kachin State; L. assamensis S.Dey, Mood, & S.Choudhury, sp. nov., is restricted to Assam, India; and L. arunachalensis M.Sabu, Sanoj & T.Rajesh Kumar, sp. nov., has only been found in Arunachal Pradesh, India. A phylogenetic analysis using the plastid trnK intron and nuclear ITS DNA sequence data indicates that the four species of Larsenianthus form a monophyletic lineage that is sister to Hedychium, a geographically widespread genus of about 50 species in tribe Zingibereae of subfamily Zingiberoideae. A dichotomous key and three-locus DNA barcodes are provided as aids for the identification of the four species of Larsenianthus.
