Chloris halophila

HABIT Perennial. Stolons present. Basal innovations flabellate. Culms 15–50 cm long. Leaf-sheaths glabrous on surface. Ligule a ciliate membrane. Leaf-blades 5–10 cm long; 2–3 mm wide. Leaf-blade surface smooth, or scabrous; glabrous; hairless except near base. Leaf-blade apex obtuse.

INFLORESCENCE Inflorescence composed of racemes.

Racemes 4–13; digitate; in several whorls; unilateral; 3.5–12 cm long. Rhachis subterete; scabrous on surface. Spikelet packing broadside to rhachis; lax; regular.

Spikelets appressed; solitary. Fertile spikelets sessile.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; 3.8–5.5 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; 1.5–3 mm long; 0.4–0.6 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; 3.7–5.3 mm long; 0.9 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; 3.8–5.5 mm long; cartilaginous; keeled; 3 -veined. Lemma margins ciliate. Lemma apex acute, or acuminate; awned; 1 -awned. Principal lemma awn subapical; 9–26 mm long overall. Apical sterile florets 1 in number; barren; linear, or lanceolate; 1.5–2.5 mm long. Apical sterile lemmas acute, or acuminate; awned; 1 -awned. Apical sterile lemma awns 7–13 mm long; 1 per spikelet in number.

FLOWER Lodicules 2; cuneate; fleshy. Anthers 3; 0.7 mm long. Stigmas 2.

FRUIT Caryopsis with adherent pericarp; ellipsoid; dorsally compressed; trigonous; 1.9–2.4 mm long.

DISTRIBUTION South America: western South America and southern South America.
