Notes: Dey and Prasanna (2019) reduced T. polyanthus as a variety of T. jacquemontii , which is not accepted here, as our field studies showed both as two distinct species though they may look similar in herbarium specimens. Tripogon jacquemontii can easily be distinguished by its glaucous leaves and culms, and awns either shorter than the lemma or occasionally almost absent.
