Subsp. schoenanthus has a looser inflorescence with longer racemes (20–30 mm.) and the lower glume of the sessile spikelet glabrous on the back. It occurs north of the Sahara and in Arabia, but the two subspecies intergrade where they meet in the Horn of Africa.It is sometimes confused with the Asiatic (Iraq to India) species C. jwarancusa (Jones) Schult., whose lowermost pedicel is not swollen.
