Agrostis parviflora

HABIT Annual; caespitose; clumped loosely. Culms erect, or geniculately ascending; weak; 15–35 cm long; 2 -noded. Culm-nodes glabrous. Leaves mostly basal. Leaf-sheaths loose. Ligule an eciliate membrane; 1–2 mm long; obtuse. Leaf-blades involute; 1–10 cm long; 0.25–1 mm wide. Leaf-blade surface smooth. Leaf-blade margins scabrous.

INFLORESCENCE Inflorescence a panicle.

Panicle open; pyramidal; 3–9 cm long; 2–7 cm wide; bearing few spikelets. Primary panicle branches 1–3 -nate.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; 1.5–2 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus glabrous.

GLUMES Glumes persistent; similar; exceeding apex of florets; firmer than fertile lemma; gaping. Lower glume lanceolate; 1 length of upper glume; membranous; 1-keeled; keeled above; 1 -veined. Lower glume primary vein scaberulous. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 1.1 length of adjacent fertile lemma; membranous; 1-keeled; keeled above; 1 -veined. Upper glume primary vein scaberulous. Upper glume lateral veins absent. Upper glume apex acute.

FLORETS Fertile lemma lanceolate; 1.3–1.8 mm long; hyaline; without keel; 5 -veined. Lemma lateral veins extending close to apex. Lemma apex truncate; muticous. Palea absent or minute.

FLOWER Lodicules 2; membranous. Anthers 3; 0.3–0.4 mm long.

FRUIT Caryopsis with adherent pericarp; ellipsoid. Hilum linear.

DISTRIBUTION Australasia: Australia.
