Agrostis comorensis

HABIT Perennial. Culms erect; 50 cm long; 2 -noded. Culm-internodes distally glabrous. Leaf-sheaths striately veined; glabrous on surface. Ligule an eciliate membrane; 4 mm long. Leaf-blades erect; 10–20 cm long; 1.5 mm wide. Leaf-blade surface glabrous.

INFLORESCENCE Inflorescence a panicle.

Panicle open; linear; 11–15 cm long; 0.5–1 cm wide. Primary panicle branches 3 cm long. Panicle branches capillary.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels 1.5–3 mm long; tip widened.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 4 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus pubescent. Floret callus hairs 0.4 mm long; 0.17 length of lemma.

GLUMES Glumes persistent; similar; exceeding apex of florets; firmer than fertile lemma; gaping. Lower glume lanceolate; 4 mm long; 1.1 length of upper glume; membranous; 1 -veined. Lower glume lateral veins absent. Lower glume apex acuminate. Upper glume lanceolate; 3.7 mm long; 1.5 length of adjacent fertile lemma; membranous; 1 -veined. Upper glume lateral veins absent. Upper glume apex acuminate.

FLORETS Fertile lemma oblong; 2.4 mm long; membranous; without keel; 5 -veined. Lemma surface puberulous. Lemma apex dentate; truncate; awned; 2 -awned. Principal lemma awn dorsal; arising 0.5 way up back of lemma; straight, or curved; 4 mm long overall. Palea 1.8 mm long; 0.75 length of lemma; hyaline.

DISTRIBUTION Africa: western Indian ocean.
