Ehrharta bulbosa

HABIT Perennial; caespitose. Rhizomes elongated. Culms 35–70 cm long; swollen at the base; forming an ovoid corm. Ligule an eciliate membrane. Leaf-blades flat, or convolute; 6–35 cm long; 4–8 mm wide. Leaf-blade margins unthickened.

INFLORESCENCE Inflorescence a panicle.

Panicle open, or contracted; linear; equilateral; 7–20 cm long. Primary panicle branches appressed, or ascending; 1–3 -nate; simple.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; laterally compressed; 7–10 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus pubescent.

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 apex acuminate. Upper glume ovate; 0.33–0.5 length of adjacent fertile lemma; hyaline; without keels; 5 -veined. Upper glume apex acuminate.

FLORETS Basal sterile florets similar; barren; without significant palea; attached to and deciduous with the fertile. Lemma of lower sterile floret elliptic (margins involute below); 1 length of spikelet; cartilaginous; 1-keeled; 5 -veined; prominently veined (below); rugose; rough throughout; ciliolate on midvein; obtuse; muticous, or awned. Awn of lower sterile floret 1–2 mm long. Lemma of upper sterile floret elliptic; 1 length of lower sterile floret; cartilaginous; rugose above; ciliolate on midvein; acute; muticous, or awned. Awn of upper sterile floret 1–2 mm long. Fertile lemma elliptic; 6–9 mm long; cartilaginous; shiny; keeled; 5 -veined. Lemma apex obtuse. Palea 2 -veined. Palea keels approximate.

FLOWER Lodicules 2; membranous.

DISTRIBUTION Africa: south.
