Chloris burmensis

HABIT Perennial. Leaf-sheaths glabrous on surface. Ligule a ciliolate membrane. Leaf-blades 10–18 cm long; 5–16 mm wide. Leaf-blade surface scabrous; rough adaxially. Leaf-blade apex acuminate.

INFLORESCENCE Inflorescence composed of racemes. Peduncle glabrous.

Racemes 7–9; digitate; ascending; unilateral; 6–18 cm long. Rhachis subterete; scabrous on surface. Spikelet packing broadside to rhachis; regular.

Spikelets appressed; solitary. Fertile spikelets sessile.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; 2.5–2.8 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus bearded; obtuse.

GLUMES Glumes persistent; similar; reaching apex of florets, or exceeding apex of florets; thinner than fertile lemma; gaping. Lower glume lanceolate, or ovate; 1.7–2.2 mm long; 0.7–0.8 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume primary vein scaberulous. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate, or ovate; 2.5–3.2 mm long; 1–1.1 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume primary vein scaberulous. Upper glume lateral veins absent. Upper glume apex acute.

FLORETS Fertile lemma elliptic; laterally compressed; 2.5–2.8 mm long; cartilaginous; keeled; 3 -veined. Lemma midvein ciliate. Lemma margins ciliate. Lemma apex acute; awned; 1 -awned. Principal lemma awn subapical; 1–2 mm long overall. Apical sterile florets 2 in number; barren; in a clump; cuneate; 1.5–1.7 mm long. Apical sterile lemmas pilose; adorned on keel; obtuse, or acute; awned; 1 -awned. Apical sterile lemma awns 0.7–1.6 mm long; 2 per spikelet in number.

FLOWER Lodicules 2; cuneate; fleshy. Anthers 3; 0.4 mm long. Stigmas 2.

FRUIT Caryopsis with adherent pericarp; dorsally compressed; trigonous.

DISTRIBUTION Asia-tropical: Indo-China.
