Eragrostis concinna

HABIT Perennial; caespitose. Culms 40–80 cm long. Leaves mostly basal. Leaf-sheaths glabrous on surface. Leaf-sheath oral hairs ciliate. Ligule a fringe of hairs. Leaf-blades convolute; 6–20 cm long; 1–4 mm wide; stiff. Leaf-blade apex attenuate.

INFLORESCENCE Inflorescence a panicle.

Panicle open; lanceolate, or ovate; 15–30 cm long. Primary panicle branches distant; simple; 2–8 cm long.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 22–50 fertile florets; with diminished florets at the apex. Spikelets linear, or oblong; laterally compressed; 12–25 mm long; 3.5 mm wide; breaking up at maturity; rhachilla persistent; retaining paleas.

GLUMES Glumes deciduous; similar; shorter than spikelet. Lower glume lanceolate; 2 mm long; 0.7–0.8 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 2.5 mm long; 0.7–0.8 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume apex acute.

FLORETS Fertile lemma ovate; 3.25 mm long; membranous; keeled; 3 -veined. Lemma lateral veins distinct. Lemma apex obtuse. Palea 0.5 length of lemma. Palea keels ciliolate. Palea apex obtuse. Apical sterile florets resembling fertile though underdeveloped.

FLOWER Lodicules 2; cuneate; fleshy. Anthers 3; 0.2 mm long.

FRUIT Caryopsis with adherent pericarp; orbicular; isodiametric; 0.5 mm long.

DISTRIBUTION Australasia: Australia.
