Axonopus moronei

HABIT Perennial; caespitose; clumped densely. Basal innovations flabellate. Culms slender; 6–20 cm long. Culm-internodes 2–3.8 cm long. Culm-nodes black; glabrous. Lateral branches lacking. Leaf-sheaths 1–4.4 cm long; keeled; glabrous on surface; outer margin hairy. Ligule a ciliate membrane; 0.1–0.3 mm long. Leaf-blades lanceolate; flat, or conduplicate; 1.2–5.8 cm long; 3–6 mm wide. Leaf-blade surface scaberulous; pilose. Leaf-blade apex acute.

INFLORESCENCE Inflorescence composed of racemes; with 1–2 peduncles per sheath. Peduncle 2.4–11.7 cm long; glabrous.

Racemes 3; digitate; ascending; unilateral; 2–3.5 cm long. Central inflorescence axis 0.4–0.9 cm long. Rhachis angular; with scattered hairs; scaberulous on margins. Spikelet packing adaxial; regular; 2 -rowed. Raceme-bases brief; pubescent.

Spikelets appressed; solitary. Fertile spikelets sessile.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; 1.2–1.4 mm long; 0.5–0.7 mm wide; falling entire.

GLUMES Glumes one the lower absent or obscure; reaching apex of florets; thinner than fertile lemma. Upper glume elliptic; 1 length of adjacent fertile lemma; 1 length of spikelet; membranous; without keels; 0–2 -veined. Upper glume primary vein absent. Upper glume lateral veins absent, or obscure.

FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret similar to upper glume; elliptic; 1 length of fertile lemma; 1 length of spikelet; 0–2 -veined; without midvein; without lateral veins, or obscurely veined. Fertile lemma elliptic; 1.2–1.4 mm long; indurate; yellow; shiny; without keel. Lemma surface papillose. Lemma margins involute. Lemma apex obtuse; without ornament. Palea involute; indurate.

FLOWER Lodicules 2; 0.3 mm long. Anthers 3; 1–1.2 mm long; purple.

DISTRIBUTION South America: western South America.
