Contribution to the knowledge on the flora of northern Mongolia

Abstract

Field surveys were conducted in the northern part of Mongolia in 2017 and 2018. Vascular plants floristic data are based on collections from the study area, and more than 800 new collections are made in this study. In total, 289 taxa (8 subspecies and 6 variates) were identified, representing 173 genera from 60 families of vascular plants. The families most diverse in species were Rosaceae with 28 taxa, followed by Ranunculaceae (25 taxa), Asteraceae (19 taxa), and Fabaceae (19 taxa). The largest genera were Salix with 11 species, followed by Viola (9 species) and Carex (9 species). Thirty-seven taxa are newly recorded for Mongolian Dauria (8), Khangai (8), Khentei (4) and Khuvsgul (17) regions. Several threatened species were found in the field area. We provide photographs and distribution maps for species of Cypripedium (C. calceolus L., C. guttatum Sw., C. macranthos Sw., and C. ventricosum Sw.). In addition, Campanula cervicaria was newly recorded for the flora of Mongolia. Keywords: Campanula, Cypripedium, New records, Northern Mongolia, Plant diversity
