Panicum glaucocladum

HABIT Annual. Culms decumbent; weak; 6–30 cm long. Ligule a ciliolate membrane. Leaf-blades lanceolate; 1–2(–3) cm long; 2–3(–7) mm wide; flaccid.

INFLORESCENCE Inflorescence a panicle.

Panicle open; obovate; effuse; 2–6 cm long. Panicle branches capillary.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; acute; 1–1.5 mm long; falling entire; readily shedding fertile florets.

GLUMES Glumes similar; reaching apex of florets; thinner than fertile lemma. Lower glume ovate; 0.5 length of spikelet; membranous; without keels; 3 -veined. Lower glume surface glabrous, or pubescent. Lower glume apex acute. Upper glume ovate; 1 length of spikelet; membranous; without keels; 5 -veined. Upper glume surface glabrous, or pubescent. Upper glume apex acute.

FLORETS Basal sterile florets barren; with palea. Lemma of lower sterile floret similar to upper glume; ovate; 1 length of spikelet; membranous; 5 -veined; glabrous, or pubescent; acute. Fertile lemma oblong; dorsally compressed; 0.7–1 mm long; chartaceous; grey; without keel. Lemma surface tuberculate (verruculose). Lemma margins involute. Lemma apex obtuse. Palea involute; chartaceous. Palea surface tuberculate (verruculose).

DISTRIBUTION Africa: west tropical.

NOTES Paniceae. FWTA.
