Article
Section Stenopoa is one of the most significant among the bluegrasses, and its proper identifying is important task. The epidermal characters, which determine the degree of roughness of the bluegrasses, are used widely in botanical literature, but the information on bluegrasses characters is controversial frequently. This work is devoted to the...

The Siberian kandyk (Erythronium sibiricum (Fisch. et Mey.) Kryl.) is listed in the Red Books of the Russian Federation and in the regions where it grows. The Siberian kandyk is widespread in Southern Siberia and Mongolia. This species has many useful qualities, for example, it is used for decorative purposes, for introduction, in folk medicine and...
Article
Numerous high‐elevation alpine plants of the Qinghai‐Tibet Plateau (QTP) also have disjunct distribution in adjacent low‐altitude mountains. The out‐of‐QTP versus into‐the‐QTP hypothesis of alpine plants provide strong evidence for the highly disputed assumption of the massive ice sheet developed in the central plateau during the Last Glacial Maxim...

Poa scabriculmis N.R. Cui, 1987, is known as endemic species of alpines of Kunlun Mountains (Xinjiang Province, NW China). Later, in Flora of China, it was treated as subspecies of polytypical species P. albertii Regel, and sinonimized with other four relative species. In this work we restore the status of this species and present its new occurrenc...

Although alien and invasive plant species have been researched extensively in the European part of Russia, the situation in Siberia is another matter. Hitherto, alien and invasive species in Siberia have not received much attention because this problem was not especially acute in Siberia. The lack of attention on alien and invasive species in Siber...
