Chloris lamproparia

HABIT Annual; caespitose. Culms geniculately ascending, or decumbent; (10–)30–55 cm long; without nodal roots, or rooting from lower nodes. Leaf-sheaths keeled. Ligule a ciliolate membrane. Leaf-blades 4–16(–20) cm long; 3–5 mm wide. Leaf-blade apex attenuate.

INFLORESCENCE Inflorescence composed of racemes; subtended by an inflated leaf-sheath; embraced at base by subtending leaf.

Racemes 2–4; paired, or digitate; erect; unilateral; 4–11 cm long. Spikelet packing broadside to rhachis.

Spikelets solitary. Fertile spikelets sessile.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; 2–2.5 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus pubescent; obtuse.

GLUMES Glumes persistent; similar; exceeding apex of florets; thinner than fertile lemma; gaping. Lower glume lanceolate; 3–4.5 mm long; 0.5 length of upper glume; chartaceous; dark brown; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume apex acuminate. Upper glume lanceolate; 5.5–8 mm long; 1.8–2 length of adjacent fertile lemma; membranous; dark brown; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume apex acuminate.

FLORETS Fertile lemma ovate; laterally compressed; ovate in profile; 3–4 mm long; coriaceous; dark brown; keeled; 3 -veined. Lemma midvein ciliate. Lemma lateral veins close to margins. Lemma margins ciliate. Lemma hairs white; 1.5–4 mm long. Lemma apex obtuse; awned; 1 -awned. Principal lemma awn subapical; 4–6 mm long overall. Apical sterile florets 3 in number; barren; in a clump; cuneate. Apical sterile lemmas awned (one ot them); 1 -awned. Apical sterile lemma awns subapical; 1 per spikelet in number.

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

FRUIT Caryopsis with adherent pericarp; trigonous. Hilum punctiform.

DISTRIBUTION Africa: west tropical, west-central tropical, northeast tropical, and east tropical.

NOTES Cynodonteae. FTEA.
