Eremochloa maxwellii

HABIT Perennial. Rhizomes elongated. Basal innovations extravaginal. Culms 8 cm long. Culm-internodes hollow; distally glabrous. Culm-nodes glabrous. Leaf-sheaths glabrous on surface. Ligule an eciliate membrane; 1 mm long. Leaf-blades flat, or conduplicate; 6–15 cm long; 3 mm wide. Leaf-blade surface glabrous. Leaf-blade margins glabrous. Leaf-blade apex acute.

INFLORESCENCE Inflorescence composed of racemes.

Racemes 1; single; straight; unilateral; 5–10 cm long. Rhachis fragile at the nodes; with scattered hairs; glabrous on margins. Rhachis internodes clavate; 3–3.5 mm long; 0.6–0.66 length of fertile spikelet. 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; 3.5–4.3 mm long; 0.7–0.9 length of fertile spikelet.

STERILE SPIKELETS Companion sterile spikelets rudimentary; linear; 1–1.2 mm long.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; compressed strongly; 5–5.5 mm long; 1.7–2 mm wide; falling entire; deciduous with accessory branch structures. Spikelet callus base truncate; with central boss; attached transversely.

GLUMES Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume oblong; 1 length of spikelet; chartaceous; 2-keeled; winged on keel; winged narrowly; winged near apex; 6–7 -veined. Lower glume lateral veins transversely connected at apex. Lower glume surface flat; glabrous. Lower glume apex truncate; awned; 2 -awned. Lower glume awn 2–3 mm long. Upper glume oblong; 4.8–5 mm long; chartaceous; 1-keeled; keeled below. Upper glume surface glabrous.

FLORETS Basal sterile florets male; with palea. Lemma of lower sterile floret elliptic; hyaline. Fertile lemma elliptic; hyaline; without keel.

FLOWER Anthers 3; 1.9 mm long.

DISTRIBUTION Asia-tropical: Indo-China.
