Notes
E. tripsacoides intergrades with E. muticus, occasional specimens with sparingly branched culms and slightly hairy spikelets sometimes being hard to place. It is barely distinguishable from E. platypus (Trin.) Hack., a species from the western side of Africa with flat leaf-blades 2–6 mm. wide, and villous internodes (hairs 2–5 mm. long). Rather more distinct is E. hensii K. Schum. from Zaire and Angola, which can be recognized by its smaller sessile spikelet (3–4 mm.) and shortly awned pedicelled spikelet.
