Enteropogon mollis

HABIT Annual. Basal innovations flabellate. Culms 40–60 cm long. Leaf-sheaths pilose. Ligule a fringe of hairs. Leaf-blades 10–30 cm long; 2–10 mm wide. Leaf-blade surface pilose; hairy on both sides.

INFLORESCENCE Inflorescence composed of racemes.

Racemes 3–7; digitate; radiating; unilateral; 6–9 cm long. Rhachis angular. 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; 2.5–6.8 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; 3–4 mm long; 0.9–1 length of upper glume; hyaline; without keels; 1 -veined. Lower glume primary vein scaberulous. Lower glume lateral veins absent. Lower glume apex acuminate. Upper glume lanceolate; 3–4.6 mm long; 0.7–1.2 length of adjacent fertile lemma; hyaline; without keels; 1 -veined. Upper glume primary vein scaberulous. Upper glume lateral veins absent. Upper glume apex acuminate.

FLORETS Fertile lemma lanceolate; dorsally compressed; 2.5–6.8 mm long; coriaceous; keeled; 3 -veined. Lemma margins ciliate; hairy above. Lemma apex acute; awned; 1 -awned. Principal lemma awn subapical; 4–7.5 mm long overall. Palea 2 -veined. Rhachilla extension pubescent; hairy at tip. Apical sterile florets 1(–2) in number; linear (when present the upper reduced to rhachilla); 1.2–1.6 mm long. Apical sterile lemmas pilose; adorned on margins; acute; awned; 1 -awned. Apical sterile lemma awns 3.7–5.8 mm long.

FRUIT Caryopsis linear; flattened; concavo-convex; 3.3 mm long.

CLEISTOGENES AND VIVIPARY Cleistogenes absent, or present.

DISTRIBUTION South America: Mesoamericana, Caribbean, northern South America, western South America, and Brazil.
