New findings in the flora of Mongolia. Part 2

Abstract

New data on the distribution of 40 species from the families Asteraceae, Cystopteridaceae, Dryopteridaceae, Euphorbiaceae, Poaceae, Rosaceae, and Woodsiaceae in Mongolia are presented in the article. For the first time, Centaurea cyanus, Cystopteris almaatensis, Potentilla × habievii, Potentilla salsa, and Potentilla smirnovii are indicated for the flora of the country. 19 species previously known in the flora of Mongolia are new for its separate botanical and geographical regions. Of these, 7 taxa were found for the first time in the Khuvsgul, 5 – in the Khovd, 4 – in the Gobi Altai and 3 – in the Mongolian Altai regions, 2 each – in the Khangai, Khentei, and Dzungarian Gobi, 1 – in the Middle Khalkha. New locations were registered for 19 rare and endemic species of the study region. There are narrow local national endemics: Potentilla coriacea, P. inopinata, P. laevipes, and P. schmakovii, among them. The findings are divided into three groups in the article. Comments about the range, relationships and main morphological differences are given for each species. Photographic materials of Potentilla salsa made in nature on the territory of Mongolia are demonstrated for the first time.
