Abstract: A few species names in Cytisus sect. Tubocytisus are re-assessed and taxonomically evaluated. Diagnostic characters are discussed and the species status of C. absinthioides Janka, C. eriocarpus Boiss., C. frivaldszkyanus Degen, C. jankae Velen. and C. smyrnaeus Boiss. is confirmed. The holotype of Cytisus triflorus Lam. was found to belong to C. hirsutus L. rather than to the C. ratisbonensis group as currently treated. Cytisus lasiosemius Boiss. is not the correct name for C. frivaldszkyanus Degen, but another synonym of C. hirsutus. Cytisus litwinowii V.I.Krecz., which was known solely from the holotype, is a synonym of C. austriacus L. s.str. Chamaecytisus pseudojankae Pifkó & Barina, reported from a small area shared between Albania, Greece and North Macedonia, is treated as a subalpine variant of C. austriacus. Cytisus tmoleus Boiss. is removed from the synonymy of C. eriocarpus and added to the synonymy of C. pygmaeus Willd. Cytisus falcatus subsp. albanicus Degen & Dörfl. and C. pubescens Gilib. are synonymised with C. hirsutus. Cytisus microphyllus Boiss. is moved from C. austriacus s.l. to the synonymy of C. frivaldszkyanus, and C. pindicola (Degen) Halácsy to the synonymy of C. jankae. Chamaecytisus calcareus (Velen.) Kuzmanov is accepted as Cytisus calcareus (Velen.) Sennikov & Val.N.Tikhom., comb. nov., and its distribution is circumscribed. Cytisus hirsutus var. ciliatus (Wahlenb.) Hazsl. and C. polytrichus var. subglabratus Val.N.Tikhom. & Sennikov, var. nov. are recognised as glabrous variants of the corresponding species. Lectotypes of C. ciliatus, C. hirsutissimus K.Koch, C. jankae, C. lasiosemius, C. pubescens, C. rhodopeus J.Wagner ex Bornm. and C. thirkeanus K.Koch are designated. Cytisus polytrichus is reported from the Western Caucasus in place of C. wulffii auct.

Centaurea lovricii, a new species of C. sect. Centaurea (Asteraceae) from Croatia https://phytokeys.pensoft.net/article/89404/ PhytoKeys 214: 97-114

DOI: 10.3897/phytokeys.214.89404

Authors: Sandro Bogdanović, Igor Boršić, Ivica Ljubičić, Salvatore Brullo, Gianpietro Giusso del Galdo

Abstract: A new species, Centaurea lovricii, is described and illustrated from the island of Vis (Dalmatia, Croatia). It occurs on northwest-facing calcareous cliffs near the sea, where it grows with several other rare endemic species. Centaurea lovricii is morphologically similar to C. glaberrima and C. divergens of C. sect. Centaurea, from which it differs in having more succulent leaves with larger and less incised leaflets, bigger capitula, larger phyllaries with more developed appendages and denser and undulate fimbriae, larger florets, bigger achenes, and longer pappus. Its morphological features, distribution, ecology, conservation status and taxonomic affinities are examined. In addition, a new iconography and lectotypification for C. glaberrima and C. divergens is provided.

On the identity of Thymus humifusus var. aureopunctatus (Lamiaceae) and taxonomic notes on the Th. richardii complex https://phytokeys.pensoft.net/article/75412/ PhytoKeys 186: 139-158

DOI: 10.3897/phytokeys.186.75412

Authors: Llorenç Sáez, Faruk Bogunić, Salvatore Cambria, Jesús Riera, Sandro Bogdanović

Abstract: The name Thymus humifusus var. aureopunctatus, described from Bosnia and Herzegovina, is lectotypified, and its taxonomic value is discussed. Thymus richardii subsp. richardii is currently considered an endemic subspecies common to Mallorca (Balearic Islands) and Bosnia and Herzegovina from the Balkan Peninsula. Specimens identified as Th. richardii from both Balearic Islands and Bosnia and Herzegovina were studied to determine if they are indeed the same taxonomic entity. Detailed micromorphological observations and morphometric analysis, suggest that the Balkan plants (Th. humifusus var. aureopunctatus) and the Majorcan populations (Th. richardii subsp. richardii) are clearly separate entities. For the former name, based on morphological, phytochemical, biogeographical and present results, we propose the subspecific rank, as Th. richardii subsp. aureopunctatus comb. & stat. nov. Full descriptions of all five subspecies currently accepted within Th. richardii are provided.

Oenanthe millefolia (Umbelliferae), a new species record for the Turkish and Greek Flora https://phytokeys.pensoft.net/article/9093/ PhytoKeys 70: 31-40

DOI: 10.3897/phytokeys.70.9093

Authors: Ebru Doğan Güner, Mehtap Tekşen, Barış Bani

Abstract: Oenanthe millefolia (Apiaceae), which is presented as a new recorded species for the Turkish flora, was discovered for the first time in Kırklareli province of Turkey. It is also reported as a new species for the Greek flora based on an unidentified specimen which was collected from the Thrace region of Greece. In this study, an expanded morphological description, the geographical distribution, the habitat properties and the ecological features of the species are exhibited with illustrative figures. Moreover, the micromorphological and anatomical characters of the fruits and the anatomical properties of the stem, petiole, leaves and the palynological features of Oe. millefolia are determined and described for the first time.
