Axonopus singularis

HABIT Annual. Culms erect; 10–75 cm long. Ligule a ciliolate membrane; 0.5 mm long. Leaf-blades conduplicate; 5–15 cm long; 3–8 mm wide.

INFLORESCENCE Inflorescence composed of racemes.

Racemes 2–7; digitate; unilateral; 3–14 cm long. Rhachis narrowly winged; angular; 0.5 mm wide; scabrous on margins. Spikelet packing adaxial; regular; 1 -rowed.

Spikelets solitary. Fertile spikelets sessile.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets obovate (turbinate); turbinate; dorsally compressed; 3.5–4 mm long; falling entire.

GLUMES Glumes one the lower absent or obscure; exceeding apex of florets; thinner than fertile lemma. Upper glume ovate; spurred; 3.5–4 mm long; membranous; without keels; 3 -veined. Upper glume surface pubescent; hairy between veins; with a transverse fringe of hair (0.7–1mm). Upper glume hairs red. Upper glume apex obtuse.

FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret elliptic; 1 length of spikelet; membranous; 3 -veined; pubescent; with a transverse fringe of hair; bearing red hairs; bearing hairs 0.5 mm long; obtuse. Fertile lemma obovate; 2.2–2.5 mm long; indurate. Lemma margins involute. Lemma apex obtuse; pubescent. Palea indurate.
