Cymbopogon iwarancusa

(Roxb.) Schult.

Poaceae


The name of this taxon is spelled Cymbopogon jwarancusa in many publications. However, Schultes published this as "Cymbopogon iwarancusa", although Jones originally spelled it as "Jwarancusa", he did not accept the name so it is invalid there; Roxburgh validated it in 1820 as Andropogon iwarancusa.
