The name Aster alpinus var. glabratus Herbich was first published by Herbich (1834: 574) and linked with the description in Additamentum ad floram Galiciae (Herbich 1831: 44). The name was based on specimens he collected in the Pieniny Mountains, Western Carpathians, Poland. Aster alpinus var. glabratus is distinguished by its glabrous leaves which are ciliate at the margins, and involucral bracts (in the protologue inappropriately named ‘squamae calycinae’), as opposed to the nominal taxon with hairy (at least adaxially) laminae. Aster alpinus var. glabratus is widely distributed in the Western Carpathians (Poland, Slovakia) and Eastern Carpathians (Romania, Ukraine). Franz Herbich (1791–1865) visited the Pieniny Mountains in 1829, 1830 and 1832 (Herbich 1834: 564, 572). All the taxa from the Pieniny Mountains enumerated in his Additamentum were collected in 1829 (Herbich 1831: 6). Continuing a revision of Herbich’s collection, we found in the herbarium of the Ivan Franko National University of Lviv (LW) eight specimens collected by him in the Pieniny Mountains. Only two of them (LW 214582, LW 214579) come from 1829. Specimen LW 214582 is labelled A. alpinus without any intraspecific attributes. Specimen LW 214579 contains two labels with different names: A. alpinus var. glabriuscul[us] and A. alpinus var. pienninus, which, however, were never published. Remarks on the second of them conform to the diagnosis of A. alpinus var. glabratus stated in the protologue. Here we designate this specimen as the lectotype of the name A. alpinus var. glabratus (Fig. 1). On the herbarium sheet of LW 214577 the collecting date was given as ‘1829–1830–1832’; that is, the label includes all the years during which Herbich visited the Pieniny Mountains (Herbich 1834). The morphological characters of all the mentioned specimens suit the description of A. alpinus var. glabratus. The present paper is the latest in a series on the typification of the vascular plant taxa described from Poland (Cieślak & Paul 2011; Szeląg 2013; Szeląg & Kobiv 2014, 2016).
Dicranodontium schwabei Thér. & Herzog, a poorly known species from Western Patagonia in Chile, is briefly assessed taxonomically. Some morphological and anatomical details of the species are illustrated and the problems associated with the typification of its name are discussed. The conspecificity of this species and Chorisodontium aciphyllum (Hook.f. & Wilson) Broth. is confirmed and the geographical distribution and ecology of the latter species is briefly reviewed.
Abstract Didymodon validus Limpr. is not universally recognised as a species in its own right but it is often considered a variety, D. rigidulus Hedw. var. validus (Limpr.) Düll. The epithet validus was used at varietal rank only in 1923, as Barbula rigidula (Hedw.) Mitt. var. valida (Limpr.) Broth., but this taxon was actually recognised as a variety, B. rigidula var. gigantea Schlieph. ex Warnst., already in 1904, and this name is lectotypified herein. Accordingly, the transfer of this variety to Didymodon Hedw., as D. rigidulus var. giganteus (Schlieph. ex Warnst.) Ochyra & Bednarek-Ochyra, comb. nov., is effected. This is the correct name for this Central European-Central Asian montane taxon at variety rank. Didymodon validus is considered a new synonym of D. rigidulus var. giganteus.
. The taxonomic and nomenclatural history of the broadly conceived genus Bryum Hedw. is briefly outlined. Twenty-one species, originating mostly from the Southern Hemisphere and traditionally classified in this genus, have been transferred to the widely accepted segregates of Bryum , including six in Imbribryum N. Pedersen, three in Leptostomopsis (Broth.) J. R. Spence & H. P. Ramsay, one in Plagiobryoides J. R. Spence, nine in Ptychostomum Hornsch. and two in Rosulabryum J. R. Spence.
The type material of Racomitrium canescens (Hedw.) Brid. fo. erythrophyllum Sakurai from Japan is taxonomically evaluated. This form perfectly falls within the range of variation of Dilutineuron corrugatum (Bednarek-Ochyra) BednarekOchyra, Sawicki, Ochyra, Szczecińska & Plášek and, accordingly, R. canescens fo. erythrophyllum is reduced to synonymy with this species name.
