Opis:
Orthotrichum affine var. bohemicum Plášek & Sawicki, var. nova, is a confirmed record of a new variety from the Czech Republic. The new taxon is described and illustrated by photos and drawing. It is characterized by having superficial stomata and a peristome with 16 endostome segments (practically as long as exostome teeth). Molecular data indicating the phylogenetic placement of the species are presented.

Opis:
Bryological research carried out from 2008 in Tajikistan and Kyrgyzstan brought interesting data on the occurrence of epiphytic bryophytes which have not been recorded yet there. One of the species was recently described as a new (Orthotrichum pamiricum) and some of the other newly recorded species are considered as rare or endangered in the region of Middle Asia. To make detailed field monitoring of the species with the aim of mapping their distribution in a wild and complex mountainous terrain, it was necessary in the first instance to identify the area with suitable conditions for the occurrence of these species. We present an innovative modeling program MaxEnt (maximum entropy modeling), which have not previously been used for modeling either epiphytic bryophytes or in the Middle Asia region. Using 205 samples (presence-only data), percent tree cover, and seven uncorrelated bioclimatic variables, regions suitable for the occurrence of the studied species were identified. Distribution models for eight most interesting species of Orthotrichum are presented here (O. affine, O. anomalum, O. crenulatum, O. cupulatum, O. pallens, O. pamiricum, O. pumilum, and O. speciosum). They indicated appropriate areas for the most probable occurrence of the species in western Tajikistan, and southwestern and northeastern Kyrgyzstan. These results could serve as guides for future survey expeditions, and aid in the conservation of target species and our understanding of their ecology. Different environmental variables for various species were selected as the most important for modeling. However, for most species higher minimum temperatures and higher precipitation in the wettest month and mean diurnal range were the variables with the greatest contribution to the models.

Opis:
Studies on the bryophyte flora of the Southern Ocean islands and in the Antarctic are briefly reviewed and the current state of knowledge of the moss flora of Îles Kerguelen is discussed. Macrocoma tenue (Hook. & Grev.) Vitt is recorded from the Îles Kerguelen archipelago and this constitutes the first record of the genus Macrocoma (Müll. Hal.) Grout from the Subantarctic. The local plants of the species are characterized and illustrated and their ecology is discussed. Global distribution of M. tenue is reviewed and mapped. It is suggested that the type subspecies of M. tenue is a Gondwanan relictual taxon, which could have evolved on this supercontinent prior to its break-up and, subsequently, it reached Îles Kerguelen where it survived during the Pleistocene glacial epoch.

Opis:
The occurrence of two epiphytic moss species, Orthotrichum alpestre Bruch & Schimp. and O. schimperi Hammar, in the moss flora of Poland is discussed. The former represents an entirely new country record based on a specimen collected from the Polish Eastern Carpathians, whereas the latter is reinstated as a member of the Polish moss flora. The complex and entangled taxonomic and nomenclatural history of O. schimperi is outlined, sources of its confusion are discussed, and two correctly determined specimens from Poland are cited. The two species are briefly characterized and illustrated, and a key to the genera and species of Polish orthotrichaceous mosses is presented.
