Chloris clementis

HABIT Perennial. Stolons present. Basal innovations flabellate. Culms erect; 20–30 cm long. Leaf-sheaths glabrous on surface; outer margin hairy. Ligule an eciliate membrane. Leaf-blades 1–2.5 cm long; 2–4 mm wide. Leaf-blade surface glabrous. Leaf-blade apex obtuse; apiculate.

INFLORESCENCE Inflorescence composed of racemes.

Racemes 2–5; digitate; radiating; unilateral; 2–3 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; 1.5–1.8 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus bearded; obtuse.

GLUMES Glumes persistent; similar; shorter than spikelet; thinner than fertile lemma; gaping. Lower glume lanceolate, or ovate; 0.5–0.6 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; 0.7–0.8 mm long; 0.5 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 lanceolate, or elliptic; laterally compressed; 1.5–1.8 mm long; cartilaginous; keeled; 3 -veined. Lemma midvein scabrous. Lemma margins ciliate; hairy above. Lemma apex acute; awned; 1 -awned. Principal lemma awn subapical; 5.5–6.5 mm long overall. Apical sterile florets 1 in number; barren; elliptic; 0.3 mm long. Apical sterile lemmas obtuse; awned; 1 -awned. Apical sterile lemma awns 1 mm long; 1 per spikelet in number.

FLOWER Lodicules 2; cuneate; fleshy. Anthers 3. Stigmas 2.

FRUIT Caryopsis with adherent pericarp; ellipsoid; dorsally compressed; trigonous; 1.2 mm long.

DISTRIBUTION Asia-tropical: Malesia.

NOTES Cynodonteae. Anderson.
