 Orinus is an alpine genus with important values in the grass family (Poaceae). All six species recognized within this genus are distributed in the QinghaiTibet Plateau. In the past five years, we surveyed the distributions of each species in this region and collected germplasm resources, including seeds, DNA and specimens. We further used the ITS sequence variation to tentatively delimit the previously acknowledged species and found that there is no distinct boundary between species and only two distinct lineages were recognized for all six species, indicating that some species should not be treated as separate species. These data provide an important resource for further utilizing and studying this genus.

Key words: Qinghai-Tibet Plateau, Orinus, Germplasms, Species Delimitation
