- Аннотация: Bryoerythrophyllum recurvirostrum var. latinervium is cited for Eurasia (and eastern hemisphere) for a first time. It is founded on Anabarskoe Plateau (East Siberian Subarctic) and in herbarium from Mongolian Gobi. Var. latinervium differs from var. recurvirostrum by very strong nerve and more recurved (rolled) leaf margin. The morphology of Eurasian material and its diagnostic features are described. Distinction from morphologically similar Pseudocrossidium species discussed. Data of B. recurvirostrum var. latinervium ecology and world distribution is provided. Before us it was known from Arctic Alaska and northernmost Greenland. Variety is confined to regions with extremely dry climatic condition, in Arctic and subarctic territories it occurs in cryophilic, mainly calcareous steppe communities. Some differences between Greenland Alaskan and Asian material are discussed. Based on sexual condition (plants from Siberia are dioecious) and some other features the origin Asian var. latinervium from Bryoerythrophyllum rubrum is proposed. At least observed neighborhood of var. latinervium and var. recurvirostrum and considerable distinction of their morphology in our opinion disprove conception of var. latinervium like B. recurvirostrum extreme ecological form.
