Poa wardiana is perhaps only a depauperate form of P. rajbhan-darii with subglabrous lemmas, in which case the name P. wardiana has priority, but its lemmas are somewhat scabrid on the sides. The similar P. lachenensis Noltie, from India (Sikkim), differs as follows: lower glume 2.2–3 mm; lemma sides scabrid to minutely bumpy near base, keel glabrous; lower part of culms smooth, shiny, ligule margins smooth; palea smooth between keels, keels medially pilulose.
