Pseudoraphis jagonis

HABIT Perennial; mat forming. Culms prostrate; 15–40 cm long; 7–14 -noded. Culm-nodes pubescent. Ligule an eciliate membrane; 0.2–0.3 mm long. Leaf-blades 1–6 cm long; 0.5–1.5 mm wide.

INFLORESCENCE Inflorescence composed of racemes.

Racemes numerous; borne along a central axis; closely spaced; spreading; 2–3 cm long; bearing 2–4 fertile spikelets on each. Central inflorescence axis 2–5 cm long. Rhachis angular; terminating in a barren extension; extension bristle-like; extension 2–3 mm long. Spikelet packing abaxial.

Spikelets appressed; solitary. Fertile spikelets pedicelled. Pedicels 0.5–4 mm long.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 4–5 mm long; 0.6–0.8 mm wide; falling entire.

GLUMES Glumes dissimilar; reaching apex of florets; thinner than fertile lemma. Lower glume oblong; 0.2–0.3 mm long; 0.05 length of spikelet; hyaline; without keels; 0 -veined. Lower glume lateral veins absent. Lower glume apex truncate. Upper glume lanceolate; 4–5 mm long; 1 length of spikelet; membranous; without keels; 13–15 -veined. Upper glume surface smooth, or scabrous. Upper glume apex cuspidate.

FLORETS Basal sterile florets male; with palea. Lemma of lower sterile floret lanceolate; 2.5–3 mm long; 0.6–0.7 length of spikelet; membranous; 7 -veined; acuminate. Palea of lower sterile floret 2–2.2 mm long. Fertile lemma oblong; 1.5–1.7 mm long; membranous; without keel. Lemma margins flat. Lemma apex acute. Palea 1 length of lemma; membranous; without keels.

FLOWER Anthers 2; 1.5–1.7 mm long.
