Enneapogon lindleyanus
HABIT Perennial. Culms 20–45 cm long. Culm-internodes distally hirsute. Lateral branches ample; arising from lower culm, or upper culm. Ligule a fringe of hairs. Leaf-blades filiform; involute; 1–4 mm wide. Leaf-blade surface scaberulous. Leaf-blade apex acuminate.
INFLORESCENCE Inflorescence a panicle. Peduncle antrorsely scabrous above and retrorsely scabrous above.
Panicle capitate; elliptic, or ovate, or globose; 0.5–1.5 cm long; 0.5–1 cm wide.
Spikelets solitary. Fertile spikelets pedicelled.
FERTILE SPIKELETS Spikelets comprising 1 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 2–4 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; 2–4 mm long; 1 length of upper glume; membranous; without keels; 3–12 -veined. Lower glume surface glabrous, or pilose. Lower glume apex erose; truncate; muticous, or mucronate. Upper glume ovate; 2–4 mm long; 1.2–1.5 length of adjacent fertile lemma; membranous; without keels; 3–12 -veined. Upper glume surface glabrous, or pilose. Upper glume apex erose; truncate; muticous, or mucronate.
FLORETS Fertile lemma oblong; 1.6–2.6 mm long; membranous, or cartilaginous; without keel; 9 -veined. Lemma lateral veins ribbed. Lemma surface pilose; hairy below (0.33–0.5 of length); inner surface transversely fringed. Lemma margins ciliate. Lemma apex dentate; 9 -fid; awned; 9 -awned. Principal lemma awn 1.3–2.5 mm long overall; 0.8–1 length of lemma; limb plumose; hairy throughout limb. Lateral lemma awns arising on apex of lobes; subequal to principal; plumose. Palea membranous. Palea keels ciliolate; adorned above; with 0.5–0.66 of their length adorned. Palea surface pubescent; hairy on back; hairy all along. Apical sterile florets 2–3 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; plano-convex; 1.3–2 mm long; obtuse. Hilum punctiform.
DISTRIBUTION Australasia: Australia.
NOTES Pappophoreae. Kakudidi.
ADDITIONAL CHARACTERS Lemma hairs less than base of awns.
