Morphology General Habit
Perennial. Culms erect; 20-60 cm long. Ligule a ciliolate membrane. Leaf-blades filiform.
Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes. Racemes single; erect; bilateral. Rhachis fragile at the nodes; subcylindrical and excavated. Spikelet packing abaxial. Rhachis internodes oblong. Rhachis internode tip oblique. Spikelets sunken; solitary. Fertile spikelets sessile.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 3-6 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus square; glabrous; base obtuse; attached obliquely.
Fertile
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 3-6 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus square; glabrous; base obtuse; attached obliquely.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes reaching apex of florets; firmer than fertile lemma. Lower glume lanceolate; 1 length of upper glume; coriaceous; without keels; 6-7 -veined. Lower glume apex obtuse. Upper glume oblong; chartaceous.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets barren; without significant palea. Lemma of lower sterile floret oblong; hyaline; 0-2 -veined. Fertile lemma oblong; hyaline; without keel; 2 -veined. Lemma apex truncate. Palea present, or absent or minute; 0-0.2 length of lemma; without keels.
Distribution
Africa.

Morphology General Habit
Perennial.
Morphology Leaves Ligules
Ligule a very short membrane; leaf laminas involute.
Morphology Reproductive morphology Inflorescences
Inflorescence a single terminal or axillary raceme; raceme cylindrical, the spikelets borne singly on alternate sides of the rhachis; internodes semicylindrical, strongly oblique at base and apex.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelet sessile, sunk in the internode; callus obtuse; inferior glume coriaceous, broadly convex, smooth, wingless; inferior floret reduced to a hyaline lemma; superior lemma entire and awnless; palea small or suppressed.
Morphology Reproductive morphology Fruits
Caryopsis oblong-elliptic, dorsally compressed.
