Morphology General Habit
Annual; caespitose. Culms geniculately ascending, or decumbent; 10-30 cm long. Ligule an eciliate membrane; 3 mm long; lacerate. Leaf-blades 2-7 cm long; 1-3 mm wide. Leaf-blade apex abruptly acute.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle, or composed of racemes. Panicle open; oblong, or ovate; secund; 1.5-8 cm long. Primary panicle branches bearing 1-5 fertile spikelets on each lower branch. Racemes 1; single; unilateral. Rhachis angular. Spikelet packing broadside to rhachis. Spikelets appressed; solitary. Fertile spikelets pedicelled. Pedicels oblong.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 5-30 fertile florets; with diminished florets at the apex. Spikelets elliptic, or oblong; laterally compressed; compressed strongly; 6-28 mm long; 3-5 mm wide; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes obscured by lemmas; pubescent.
Fertile
Spikelets comprising 5-30 fertile florets; with diminished florets at the apex. Spikelets elliptic, or oblong; laterally compressed; compressed strongly; 6-28 mm long; 3-5 mm wide; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes obscured by lemmas; pubescent.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; similar; shorter than spikelet. Lower glume oblong; 3 mm long; 0.75 length of upper glume; coriaceous; 1-keeled; 3 -veined. Lower glume apex obtuse. Upper glume oblong; 4 mm long; 0.7-0.8 length of adjacent fertile lemma; coriaceous; 1-keeled; 3 -veined. Upper glume lateral veins ribbed. Upper glume apex obtuse.
Morphology Reproductive morphology Flowers Florets
Fertile lemma ovate; ovate in profile; 4-4.5 mm long; coriaceous; much thinner on margins; keeled; 5 -veined. Lemma midvein scaberulous. Lemma lateral veins with distinct primaries but obscure intermediates. Lemma surface pubescent; hairy below; with capitate hairs. Lemma hairs 0.2 mm long. Lemma apex obtuse. Palea 2 -veined. Palea keels scaberulous. Apical sterile florets resembling fertile though underdeveloped.
Morphology Reproductive morphology Flowers
Anthers 3; 3-3.5 mm long. Ovary glabrous.
