Enteropogon minutus

HABIT Perennial; caespitose. Culms erect; 60–90 cm long; 5–8 -noded. Leaf-sheath oral hairs bearded. Ligule a ciliolate membrane; 0.5 mm long. Collar with external ligule. Leaf-blades 6–15 cm long; 2–3.5 mm wide. Leaf-blade surface scaberulous, or scabrous. Leaf-blade apex acuminate.

INFLORESCENCE Inflorescence composed of racemes.

Racemes 3–5; digitate; erect, or ascending; flexuous; unilateral; 7–12 cm long. Rhachis angular; scabrous on surface. 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 lanceolate; laterally compressed; 3–3.5 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; 0.5 mm long; pubescent; acute.

GLUMES Glumes persistent; similar; reaching apex of florets; thinner than fertile lemma; gaping. Lower glume lanceolate; 2–5 mm long; 0.5 length of upper glume; hyaline; without keels; 1 -veined. Lower glume primary vein scaberulous. Lower glume lateral veins absent. Lower glume apex setaceously attenuate. Upper glume lanceolate; 3–3.5 mm long; 1 length of adjacent fertile lemma; hyaline; without keels; 1 -veined. Upper glume primary vein scaberulous. Upper glume lateral veins absent. Upper glume apex setaceously attenuate.

FLORETS Fertile lemma elliptic, or oblong; dorsally compressed; 3–3.5 mm long; cartilaginous; keeled; 3 -veined. Lemma surface scaberulous. Lemma apex dentate; 2 -fid; awned; 1 -awned. Principal lemma awn from a sinus; flexuous; 8–14 mm long overall. Palea 2 -veined. Rhachilla extension 1.5–2 mm long. Apical sterile florets 1 in number; linear; 1 mm long. Apical sterile lemmas dentate; 2 -fid; acute; awned; 1 -awned. Apical sterile lemma awns 5–10 mm long.

FRUIT Caryopsis flattened; concavo-convex; 1.8–2.3 mm long.

DISTRIBUTION Australasia: Australia.

NOTES Cynodonteae. Lazarides.
