Chloris humbertiana

HABIT Perennial. Stolons present; with alternating elongated and bunched internodes. Basal innovations flabellate. Culms erect; 20–30 cm long. Ligule a ciliolate membrane. Leaf-blades conduplicate; 1.5–2 cm long; 3–5 mm wide. Leaf-blade apex obtuse.

INFLORESCENCE Inflorescence composed of racemes; embraced at base by subtending leaf.

Racemes 2–3; paired, or digitate; unilateral; 3–4 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; 2.3–3.5 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus pubescent; obtuse.

GLUMES Glumes persistent; similar; shorter than spikelet; thinner than fertile lemma; gaping. Lower glume lanceolate; 1–1.5 mm long; 0.7–1 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; 1.5 mm long; 0.6 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 ovate; laterally compressed; elliptic in profile; 2.3–3.5 mm long; cartilaginous; pallid; keeled; winged on margins (above); 3 -veined. Lemma midvein eciliate. Lemma lateral veins close to margins. Lemma surface pubescent; with clavate hairs. Lemma margins eciliate. Lemma apex truncate; awned; 1 -awned. Principal lemma awn subapical; 2.4–3.5 mm long overall. Apical sterile florets 1 in number; barren; elliptic; 1 mm long. Apical sterile lemmas acute; awned; 1 -awned. Apical sterile lemma awns subapical; 3–3.8 mm long; 1 per spikelet in number.

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

FRUIT Caryopsis with adherent pericarp.

DISTRIBUTION Africa: western Indian ocean.

NOTES Cynodonteae. Anderson.
