Contribution to the knowledge of the Flora of the Mongolian Altai

During a German‐Mongolian expedition to the Mongolian Altai in July/August 2000, 404 specimens of vascular plants were collected. They are deposited in the Herbarium of the University of Osnabrück (OSBU). 381 specimens could be determined conclusively. The collected material comprises 300 species, 156 genera, and 44 families. Six of these species were first records for Mongolia, six species had not been recorded so far for the region Mongolian Altai, five are new for the region Khobdo, and 19 species new records for both regions, Mongolian Altai and Khobdo, Western Mongolia. A list of the collected plants with accession numbers and provenances is presented.
