A new species for Mongolia and new records of vascular plants from Dzungarian Gobi

Abstract

A record of Silene alexandrae B. Keller converts it to a new species for Mongolia. S. alexandrae was found on the Khavtag Mountain ranges in Dzungarian Gobi region. Data about previous records of this species in Mongolia are discussed and rejected. Characters distinguishing Silene alexandrae from close species S. altaica Pers. are given. We noted also new distribution points of fve taxa: Cortusa matthioli L. subsp. altaica (Losinsk.) Korobkov, Ranunculus turczaninovii (Luferov) Vorosch., Rubus saxatilis L., Polygonatum odoratum (Mill.) Druce and Pyrola rotundifolia L. – in Dzungarian Gobi region of Mongolia.
