Ehrharta longigluma

HABIT Perennial. Rhizomes elongated. Culms 20–60 cm long. Culm-nodes pubescent. Ligule an eciliate membrane. Leaf-blades 2.5–12 cm long; 2–4 mm wide. Leaf-blade surface pubescent.

INFLORESCENCE Inflorescence a panicle.

Panicle open; lanceolate, or ovate; 6–13 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; 4–7.5 mm long; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes persistent; similar; exceeding apex of florets; thinner than fertile lemma. Lower glume ovate; 0.9 length of upper glume; hyaline; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acuminate. Upper glume ovate; 1.2–1.5 length of adjacent fertile lemma; hyaline; without keels; 1 -veined. Upper glume lateral veins absent. 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; 0.75 length of spikelet; cartilaginous; 1-keeled; 5 -veined; smooth; obtuse. Lemma of upper sterile floret elliptic; basally auriculate; 3.5–5.2 mm long; 1.3 length of lower sterile floret; cartilaginous; smooth; obtuse. Fertile lemma elliptic; 3.5–5.2 mm long; cartilaginous; keeled; 5 -veined. Lemma apex obtuse. Palea 2 -veined. Palea keels approximate.

FLOWER Lodicules 2; membranous.

DISTRIBUTION Africa: south.
