Notes
E. namaquensis belongs to a small group of closely allied species with membranous ligules, which have been treated as a separate genus Diandrochloa de Winter. I have preferred to defer judgement until variation within the genus as a whole has been more closely studied.  The two varieties differ in their overall geographical distribution, and are often treated as species. On the other hand they are sympatric throughout tropical Africa, and the only reliable distinction between them is the roughness of their palea-keels, a character needing careful dissection under a strong lens.
