Melinis kallimorpha

HABIT Annual; caespitose. Culms decumbent; slender; 30–100 cm long; (0.5–)0.7–1.4(–1.8) mm diam.; rooting from lower nodes. Culm-nodes glabrous, or pubescent. Ligule a fringe of hairs; 0.6–1.1(–1.4) mm long. Leaf-blades 3–15 cm long; 1–3(–5) mm wide.

INFLORESCENCE Inflorescence a panicle.

Panicle open; linear, or oblong; 5–12 cm long; 1–2(–3) cm wide.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels glabrous.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong, or ovate; laterally compressed; gibbous; 3–5 mm long; falling entire. Rhachilla internodes elongated between glumes (0.4–0.8mm).

GLUMES Glumes dissimilar; reaching apex of florets; thinner than fertile lemma. Lower glume oblong; 0.5–1.5 mm long; 0.15–0.3 length of spikelet; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume surface glabrous, or pubescent. Lower glume apex emarginate, or truncate. Upper glume oblong; gibbous; 1 length of spikelet; coriaceous; of similar consistency above; dark brown; without keels; 5 -veined. Upper glume surface glabrous, or pubescent; hairy below; without hair tufts, or with a dorsal tuft of hair. Upper glume margins eciliate, or ciliate. Upper glume hairs white, or purple. Upper glume apex emarginate and rostrate; muticous (rarely), or awned; 1 -awned. Upper glume awn 3–10 mm long.

FLORETS Basal sterile florets barren; with palea. Lemma of lower sterile floret similar to upper glume; oblong; 1 length of spikelet; coriaceous; of similar consistency above; 5 -veined; glabrous, or pubescent; hairy below; emarginate; muticous, or awned. Awn of lower sterile floret 3–10 mm long. Palea of lower sterile floret pilose. Fertile lemma oblong; laterally compressed; 2.5 mm long; cartilaginous; shiny; without keel; 5 -veined. Lemma margins flat. Palea cartilaginous; without keels.

FLOWER Stigmas laterally exserted.

DISTRIBUTION Africa: east tropical, southern tropical, and south.

NOTES Paniceae. FTEA.
