Ehrharta delicatula

HABIT Annual. Culms 4.5–25 cm long. Ligule an eciliate membrane. Leaf-blades 2–16 cm long; 1–11 mm wide; flaccid.

INFLORESCENCE Inflorescence a panicle.

Panicle open; lanceolate; 6–12 cm long. Primary panicle branches spreading.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; laterally compressed; 2–3 mm long; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes persistent; similar; shorter than spikelet; thinner than fertile lemma. Lower glume ovate; 0.9 length of upper glume; hyaline; without keels; 3 -veined. Lower glume surface glabrous, or pubescent. Lower glume apex acuminate. Upper glume ovate; 0.66–0.75 length of adjacent fertile lemma; hyaline; without keels; 5 -veined. Upper glume surface glabrous, or pubescent. Upper glume apex acuminate.

FLORETS Basal sterile florets dissimilar; barren; without significant palea; attached to and deciduous with the fertile. Lemma of lower sterile floret elliptic; 1 length of spikelet; cartilaginous; 1-keeled; 5 -veined; rugose; obtuse. Lemma of upper sterile floret elliptic; basally auriculate; 1 length of lower sterile floret; cartilaginous; rugose throughout; obtuse. Fertile lemma elliptic; 2–3 mm long; cartilaginous; keeled; 5 -veined. Lemma apex obtuse. Palea 2 -veined. Palea keels approximate.

FLOWER Lodicules 2; membranous.

DISTRIBUTION Africa: south.
