Abstract
In Nepal the Stipeae consists of six genera: Achnatherum, Orthoraphium, Piptatherum, Ptilagrostis, Stipa, Trikeraia, and 15 species. Two new combinations, Ptilagrostis duthiei (Hook. f.) M.Nobis & P.D.Gudkova and Achnatherum staintonii (Bor) M.Nobis & P.D.Gudkova, are proposed, and new country records for Stipa klimesii, Ptilagrostis dichotoma, Ptilagrostis concinna and Achnatherum jacquemontii are reported. The records of Stipa roborowskyi, S. przewalskyi, S. capillata, S. consanguinea, S. mongholica, and S. sibirica, previously thought to occur in Nepal were based on misidentifications, and these have been excluded from the list of Nepalese Stipeae. We present keys for the identification of genera and species, and a checklist including information on nomenclatural types, regional and national distribution, and habitat. A lectotype is designated for Stipa brandisii Mez.
