Poa pseudamoena

HABIT Annual; caespitose. Culms 2–4 cm long. Lateral branches lacking. Leaf-sheaths smooth; glabrous on surface. Ligule an eciliate membrane; 0.5 mm long; acute. Leaf-blades 2–4 cm long; 1–1.5 mm wide. Leaf-blade surface glabrous.

INFLORESCENCE Inflorescence a panicle; shorter than basal leaves.

Panicle contracted; linear; 1–2.5 cm long; 0.4–0.6 cm wide. Primary panicle branches appressed; 1–2 -nate. Panicle branches scaberulous.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 3–4 fertile florets; with a barren rhachilla extension. Spikelets elliptic; laterally compressed; 4–5 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus glabrous.

GLUMES Glumes persistent; similar; shorter than spikelet. Lower glume elliptic, or oblong; 4–4.75 mm long; 0.9 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume elliptic; 4.5–5 mm long; 1.2–1.3 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume primary vein scabrous. Upper glume apex acute.

FLORETS Fertile lemma elliptic, or oblong; elliptic in profile; 3.5–4 mm long; membranous; much thinner on margins; keeled; 5 -veined. Lemma surface glabrous. Lemma apex acute. Palea keels scaberulous; adorned above. Palea surface scabrous.

FLOWER Lodicules 2; membranous. Anthers 3; 0.6–0.75 mm long.

FRUIT Caryopsis with adherent pericarp. Hilum punctiform.

DISTRIBUTION Asia-temperate: China. Asia-tropical: India.
