Morphology General Habit
Annual; caespitose. Culms erect, or geniculately ascending; 20-40 cm long. Ligule a fringe of hairs. Leaf-blades involute; 2-3 mm wide. Leaf-blade margins eglandular.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle open; lanceolate, or ovate; effuse; 15-30 cm long; 0.66 of culm length. Primary panicle branches distant; simple. Panicle branches eglandular. Spikelets solitary. Fertile spikelets pedicelled. Pedicels 0.5-9 mm long; eglandular.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 10-26 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 8-20 mm long; breaking up at maturity; rhachilla persistent; retaining paleas; fragile above; with the distal florets disarticulating separately.
Fertile
Spikelets comprising 10-26 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 8-20 mm long; breaking up at maturity; rhachilla persistent; retaining paleas; fragile above; with the distal florets disarticulating separately.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes deciduous; similar; shorter than spikelet. Lower glume lanceolate; 1.5-2.2 mm long; 0.75 length of upper glume; eglandular; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 2.3-2.7 mm long; 0.9 length of adjacent fertile lemma; eglandular; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Fertile lemma oblong; 2.3-2.6 mm long; coriaceous; keeled; 3 -veined. Lemma midvein scabrous. Lemma lateral veins thickened. Lemma surface scaberulous; rough on veins. Lemma margins scaberulous. Lemma apex obtuse, or acute. Palea keels scabrous. Apical sterile florets resembling fertile though underdeveloped.

Type
S1, 1°34’N, 42°57’E, Beckett & White 1536 (K holo.)
Morphology General Habit
Annual up to 40 cm high, erect or geniculately ascending; leaves inrolled, without crateriform glands on the margins
Morphology Reproductive morphology Inflorescences
Panicle lanceolate to narrowly ovate, up to 30 cm long (far exceeding the length of the supporting stem), the spikelets remote and shortly (0.5–9 mm) pedicelled on the distant racemose primary branches, the branches and pedicels without crateriform glands
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets linear, 8–20 mm long, 10- to 26-flowered, shedding their florets from below upwards, the paleas persistent on the rhachilla, though the latter becoming fragile almost as soon as the lemmas start to fall; glumes unequal, lanceolate, very acute, without glands on the nerve, the lower 1.5–2.2 mm long, the upper 2.3–2.7 mm long; lemmas oblong-lanceolate in profile, subcoriaceous with thickened nerves, 2.3–2.6 mm long, scabrid on the keel, scaberulous on the lateral nerves and flanks, obtuse to subacute; palea-keels scabrid; anthers 3, c. 0.3 mm long
Morphology Reproductive morphology Fruits
Grain broadly oblong, 0.7 mm long.
Distribution
S1 known only from the type.
