Poa longii

HABIT Perennial; caespitose; clumped densely. Culms 15–31 cm long. Culm-internodes smooth. Leaf-sheaths smooth, or scaberulous. Ligule an eciliate membrane; 1–1.8 mm long; obtuse. Leaf-blades 3–6.5 cm long; 1–2 mm wide. Leaf-blade surface glabrous.

INFLORESCENCE Inflorescence a panicle.

Panicle open; pyramidal; loose; 6.5–13 cm long. Primary panicle branches reflexed; distant; 2–4 -nate. Panicle branches capillary; scabrous.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 2–4 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 3.6–5.6 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus woolly.

GLUMES Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 1.1–2.2 mm long; 0.5–0.66 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume surface scabrous. Lower glume apex acute. Upper glume oblong; 2.5–3.2 mm long; 0.8–0.9 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume surface scabrous. Upper glume apex acute.

FLORETS Fertile lemma ovate; lanceolate in profile; 2.9–3.8 mm long; 1.4 mm wide; membranous; mid-green and purple; tipped with last colour; keeled; 5 -veined. Lemma midvein ciliate; hairy below. Lemma lateral veins stopping well short of apex. Lemma surface smooth, or punctate; puberulous; hairy at base. Lemma apex acute. Palea 2.3–2.4 mm long. Palea keels scaberulous. Apical sterile florets resembling fertile though underdeveloped.

FLOWER Lodicules 2; membranous. Anthers 3; 0.7 mm long.

FRUIT Caryopsis with adherent pericarp. Hilum punctiform.

DISTRIBUTION Asia-tropical: India.
