Note.

These specimens were previously identified as P. concinna which also occurs in Nepal and which can be distinguished by its subequal glumes, lemma and palea. It has also been confused with Ptilagrostis bhutanica (Noltie) M.Nobis (basionym: Stipa bhutanica Noltie 1999: 289; Nobis et al. 2016), from Bhutan and China. However, these two taxa differ in the upper part of the awn which is scabrous in P. bhutanica and shortly pilose (with hairs over 0.5 mm long) in P. yadongensis .
