A new species of Chrysopogon (Poaceae: Andropogoneae) from India

Abstract

A new species of Chrysopogon from the lateritic hillocks of Kannur District, Kerala, India, is described and illustrated. It closely resembles C. tadulingamii, but differs mainly in having sessile spikelets with a ciliate, short-awned upper glume and a short-awned upper lemma, pedicelled spikelets with 7-nerved, awned lower glume, a short 3-nerved awnless, retrorsely ciliate upper glume and a retuse or bifid upper lemma. The new species also resembles C. asper in some characters, but differs in having acicular or linear leaf blades, rounded leaf sheaths, and sessile spikelets with short-awned upper glume and upper lemma. A key for identification of species in Chrysopogon from Kerala is also provided.
