초록

Arctium tomentosum Mill. (Asteraceae), from Ulaanbaatar in the Khentei phytogeographical region of Mongolia, is recognized here as a new genus and species of the flora of Mongolia. Arctium differs from other genera of Asteraceae by the hooked apex of the involucral bracts. While A. tomentosum is most similar to A. lappa, it is easily distinguished by the glandular hairs of the corolla limb and the widened inner involucral bracts. Taxonomic notes, a description of the morphology, detailed photos, habitat information, the phenology and a distribution map of A. tomentosum are provided.

과제정보

This study was supported by a research project (A survey on the vascular flora of Mongolia; Grant Number KNA 1-2-38, 20-5) of the Korean National Arboretum, South Korea, and partly supported by the National University of Mongolia's Seed Grant. We thank Mr. E. Choijilsuren, who found the first locations of this species in Mongolia, for providing valuable information. The authors are grateful to two anonymous reviewers and David Boufford (Harvard University Herbaria) for their critical reading of the manuscript with valuable comments.
