Inflorescence composed of racemes; terminal and axillary; subtended by a spatheole; enclosed. Spatheole lanceolate; membranous. Racemes single; unilateral; bearing few fertile spikelets; bearing 5 fertile spikelets on each (1/2), or 6-8 fertile spikelets on each (2/2), or 9-10 fertile spikelets on each (1/2). Rhachis fragile at the nodes. Spikelet packing crowded. Rhachis internodes filiform. Rhachis internode tip oblique. Spikelets in pairs. Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets pedicelled; 1 in the cluster. Pedicels filiform. STERILE SPIKELETS Companion sterile spikelets well-developed; separately deciduous. Companion sterile spikelet callus cuneate. Companion sterile spikelet glumes muticous. FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate (1), or elliptic (2), or oblong (1); dorsally compressed; 3-3.533-4 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus square (2), or oblong (1); pilose; base obtuse; attached obliquely. GLUMES Glumes exceeding apex of florets; firmer than fertile lemma. Lower glume elliptic; coriaceous; without keels; 8 -veined (1), or 9-10 -veined (2), or 11-15 -veined (1). Lower glume surface smooth (1), or scabrous (2); glabrous (1), or pilose (1), or villous (2). Lower glume apex truncate (1/2), or obtuse (1/2). Upper glume lanceolate (1), or elliptic (2); chartaceous (2/2); without keels; 3 -veined. Upper glume surface smooth (1), or scabrous (2). Upper glume apex entire (1), or dentate (2); 2 -fid (2/2); acute (1/1); awned; 1 -awned. FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret oblong; hyaline; 0 -veined (2), or 2 -veined (1); emarginate (1/1), or truncate (1/1). Fertile lemma linear; hyaline; without keel. Lemma apex lobed; 2 -fid; incised 0.4-0.5-0.6 of lemma length; awned; 1 -awned. Principal lemma awn from a sinus; geniculate. Palea absent or minute. FLOWER Anthers 3 (2/2). DISTRIBUTION Africa.
