Chloris canterae

HABIT Perennial; caespitose. Culms erect; 5–100 cm long. Leaf-sheaths glabrous on surface. Ligule a ciliate membrane; 7 mm long. Leaf-blades flat, or involute; 5–25 cm long; 1–5 mm wide. Leaf-blade surface smooth, or scabrous; glabrous, or pilose.

INFLORESCENCE Inflorescence composed of racemes.

Racemes 2–9; digitate; straight, or arcuate; unilateral; 4–14 cm long. Rhachis subterete. Spikelet packing broadside to rhachis; crowded; regular.

Spikelets appressed; solitary. Fertile spikelets sessile.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; 2.7–3.7 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus bearded; obtuse.

GLUMES Glumes persistent; similar; reaching apex of florets; thinner than fertile lemma; gaping. Lower glume lanceolate; asymmetrical; 1.6–2.4 mm long; 0.6–0.75 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; symmetrical, or asymmetrical; 2.3–3.8 mm long; 0.8–1 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume apex acute.

FLORETS Fertile lemma ovate; laterally compressed; 2.7–3.7 mm long; cartilaginous; light brown; keeled; 3 -veined. Lemma midvein ciliate; hairy all along. Lemma margins ciliate; hairy all along. Lemma hairs 1.5–3 mm long. Lemma apex acute; awned; 1 -awned. Principal lemma awn subapical; 2.4–5.5 mm long overall. Apical sterile florets 2(–3) in number; barren; in a clump; cuneate; 1.1–1.8 mm long. Apical sterile lemmas obtuse; lower awned; 1 -awned. Apical sterile lemma awns 1.5–3.5 mm long; 1 per spikelet in number.

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

FRUIT Caryopsis with adherent pericarp; ellipsoid, or ovoid; dorsally compressed; trigonous; 1.3–2 mm long.

DISTRIBUTION South America: Brazil and southern South America.

NOTES Cynodonteae. Anderson.
