Enneapogon pallidus

HABIT Perennial. Culms 30–88 cm long. Lateral branches ample. Ligule a fringe of hairs. Leaf-blades flat, or involute; 1–3 mm wide. Leaf-blade surface pubescent. Leaf-blade apex acuminate.

INFLORESCENCE Inflorescence a panicle. Peduncle antrorsely scabrous above and retrorsely scabrous above; pubescent above to hirsute above.

Panicle contracted, or spiciform; linear, or pyramidal; 5–8 cm long; 1–2.5 cm wide. Primary panicle branches 1–4.5 cm long.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 3–6.3 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; 3–6.3 mm long; 1 length of upper glume; membranous; without keels; 7–9 -veined. Lower glume surface pilose. Lower glume apex entire, or erose; truncate, or obtuse; muticous, or mucronate. Upper glume ovate; 3–6.3 mm long; 1.5–2 length of adjacent fertile lemma; membranous; without keels; 7–9 -veined. Upper glume surface pilose. Upper glume apex entire, or erose; truncate, or obtuse; muticous, or mucronate.

FLORETS Fertile lemma orbicular; 2–3.4 mm long; cartilaginous; without keel; 9 -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 3–6 mm long overall; 1.5–2 length of lemma; limb plumose; glabrescent towards tip. Lateral lemma awns arising on apex of lobes; subequal to principal; plumose. Palea 1.1 length of lemma; membranous. Palea keels ciliolate; adorned above; with 0.5–0.75 of their length adorned. Palea surface pubescent; hairy on back; hairy all along. Apical sterile florets 2 in number; barren. Apical sterile lemmas awned; 9 -awned. Apical sterile lemma awns ciliate.

FLOWER Lodicules 2. Anthers 3.

FRUIT Caryopsis with adherent pericarp; ellipsoid, or obovoid; concavo-convex; 1.3–2 mm long. Hilum punctiform.

DISTRIBUTION Asia-tropical: Malesia and Papuasia. Australasia: Australia.

NOTES Pappophoreae. Kakudidi.

ADDITIONAL CHARACTERS Lemma hairs less than base of awns.
