Eremochloa ciliatifolia

HABIT Perennial. Rootstock evident. Culms erect, or geniculately ascending; 20–40 cm long. Culm-internodes distally pilose. Culm-nodes bearded. Leaves mostly basal. Leaf-sheaths keeled; outer margin hairy. Ligule an eciliate membrane; 1.5 mm long. Leaf-blades 5–15 cm long; 4–8 mm wide. Leaf-blade margins tuberculate-ciliate; hairy all along. Leaf-blade apex abruptly acute; hooded.

INFLORESCENCE Inflorescence composed of racemes.

Racemes 1; single; arcuate; unilateral; 2–4 cm long. Rhachis fragile at the nodes; pilose on surface; glabrous on margins. Rhachis internodes clavate; 2.5–3 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 linear; flattened; 2.5–3 mm long; ciliate.

STERILE SPIKELETS Companion sterile spikelets represented by awns; comprising 1 awn (tilted on pedicel); 3.5–4 mm long.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; compressed strongly; 4.5 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. Lower glume ovate; 1 length of spikelet; coriaceous; 2-keeled; wingless; 7 -veined. Lower glume primary vein pectinately ciliate, or 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; hyaline; acute. Palea of lower sterile floret 1 length of lemma. Fertile lemma elliptic; hyaline; without keel. Lemma apex obtuse. Palea 1 length of lemma; hyaline.

FLOWER Anthers 3; 2.5 mm long.

DISTRIBUTION Asia-tropical: Indo-China.

NOTES Andropogoneae. Bor.

ADDITIONAL CHARACTERS Glume spines terete, 2–3mm.
