Enneapogon decipiens
HABIT Perennial; caespitose. Culms 28–62 cm long. Lateral branches ample. Leaf-sheaths longer than adjacent culm internode. Ligule a fringe of hairs. Leaf-blades 1–3 mm wide. Leaf-blade surface scaberulous; pilose. Leaf-blade apex attenuate; filiform.
INFLORESCENCE Inflorescence a panicle. Peduncle antrorsely scabrous above.
Panicle spiciform; linear; (1.5–)2.5–13 cm long; 1–2 cm wide.
Spikelets solitary. Fertile spikelets pedicelled.
FERTILE SPIKELETS Spikelets comprising 1 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 5.9–9.4 mm long; breaking up at maturity; disarticulating below each fertile floret.
GLUMES Glumes persistent; similar; exceeding apex of florets; thinner than fertile lemma. Lower glume ovate; 4–8 mm long; 0.6–0.8 length of upper glume; membranous; without keels; 9–14 -veined. Lower glume surface glabrous, or pubescent, or pilose. Lower glume apex entire, or erose; obtuse, or acute. Upper glume ovate; 5.9–9.4 mm long; 2 length of adjacent fertile lemma; membranous; without keels; 7–14 -veined. Upper glume surface glabrous, or pubescent, or pilose. Upper glume apex entire, or erose; emarginate, or acute.
FLORETS Fertile lemma oblate; 2.9–4.2 mm long; cartilaginous, or coriaceous; without keel; 9–11 -veined. Lemma lateral veins without ribs, or ribbed. Lemma surface pilose; hairy below; inner surface transversely fringed. Lemma margins ciliate. Lemma apex dentate; 9 -fid; awned; 9 -awned. Principal lemma awn 3.5–9 mm long overall; limb ciliate (lower 0.75–0.8 of length). Lateral lemma awns arising on apex of lobes; subequal to principal; of unequal width (outer wider); ciliate. Palea 1.1 length of lemma; cartilaginous. Palea keels ciliate; adorned all along. Palea surface glabrous (or with sparse apical hairs). Apical sterile florets 4–5 in number; dissimilar. First apical floret male. Apical sterile florets barren; in a clump. Apical sterile lemmas awned; 9 -awned. Apical sterile lemma awns ciliate.
FLOWER Lodicules 2. Anthers 3.
FRUIT Caryopsis with adherent pericarp; obovoid; concavo-convex; 1.3–2.2 mm long. Hilum punctiform.
DISTRIBUTION Australasia: Australia.
NOTES Pappophoreae. Kakudidi.
ADDITIONAL CHARACTERS Lemma hairs reaching base of awns.
