New data on the genus Geranium L. (Geraniaceae) in the flora of Mongolia and China

Abstract

The species composition of the genus Geranium (Geraniaceae) in the flora of Mongolia and China has been revised as a result of a critical study of collections of the Herbarium of V. L. Komarov Botanical Institute RAS (LE), the D. P. Syreischikov Herbarium of Biological Faculty of Moscow State University (MW), the I. M. Krasnoborov Herbarium of Central Siberian Botanical Garden (NS), Herbarium of the South Siberian Botanical Garden (ALTB), Herbarium of the Institute of General and Experimental Biology of the Academy of Sciences of Mongolia (UBA) in 2010–2017. Two taxa: G. amurense Tzyren. and G. transbaicalicum Serg. subsp. turczaninovii (Serg.) Peschkova have been identified for the first time in the flora of Mongolia. Three species (G. krylovii Tzvelev, G. laetum Ledeb., G. transbaicalicum Serg.) are newly reported for certain phytogeographic regions of Mongolia. New localities of G. affine Ledeb., G. krylovii, G. laetum and G. transbaicalicum in China have been discovered. Thus, the knowledge on the current diversity and distribution of the genus Geranium in Mongolia and China has been updated.
