Eremochloa zeylanica

HABIT Perennial. Rootstock evident. Culms erect, or geniculately ascending; 30–60 cm long; 3–4 -noded. Culm-nodes glabrous. Leaf-sheaths keeled. Ligule an eciliate membrane; 1 mm long. Leaf-blades linear, or lanceolate; 2–15 cm long; 2–5 mm wide. Leaf-blade margins scabrous; tuberculate-ciliate; hairy at base. Leaf-blade apex abruptly acute.

INFLORESCENCE Inflorescence composed of racemes.

Racemes 1; single; arcuate; unilateral; 4–7 cm long. Rhachis fragile at the nodes; angular; glabrous on surface; glabrous on margins. Rhachis internodes clavate; 3 mm long. Rhachis internode tip crateriform.

Spikelets appressed; in pairs. Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets pedicelled; 1 in the cluster. Pedicels narrowly elliptic; foliaceous; 4–5 mm long.

STERILE SPIKELETS Companion sterile spikelets represented by barren pedicels, or rudimentary; 0–1 mm long.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; compressed strongly; 5 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus bearded; base truncate; with central boss; attached transversely.

GLUMES Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma; shiny. Lower glume elliptic; 1 length of spikelet; coriaceous; 2-keeled; winged on keel; winged narrowly; winged above; 7 -veined. Lower glume primary vein pectinately spinose. Lower glume surface flat. Upper glume elliptic; chartaceous; 1-keeled; winged on keel; winged below; 3 -veined. Upper glume apex acute.

FLORETS Basal sterile florets male; with palea. Lemma of lower sterile floret elliptic; 3.5 mm long; hyaline; ciliate on margins; obtuse. Palea of lower sterile floret 1 length of lemma. Fertile lemma elliptic; 3.5 mm long; hyaline; without keel. Lemma apex acute. Palea 1 length of lemma; hyaline.

FLOWER Anthers 3; 1.5 mm long.

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

NOTES Andropogoneae. Bor.

ADDITIONAL CHARACTERS Glume spines terete, 2mm.
