Enneapogon eremophilus
HABIT Perennial; caespitose. Culms 13–36 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; glabrous. Leaf-blade apex acuminate.
INFLORESCENCE Inflorescence a panicle. Peduncle antrorsely scabrous above.
Panicle spiciform; linear; 1.5–6.5 cm long; 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; 2.5–5.4 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; 2.5–5.4 mm long; 1 length of upper glume; membranous; without keels; 4–9 -veined. Lower glume surface pubescent; with capitate hairs. Lower glume apex truncate, or obtuse. Upper glume ovate; 2.5–5.4 mm long; 1.2–1.5 length of adjacent fertile lemma; membranous; without keels; 4–9 -veined. Upper glume surface pubescent; with capitate hairs. Upper glume apex truncate, or obtuse.
FLORETS Fertile lemma oblong; 2–3.5 mm long; cartilaginous, or coriaceous; without keel; 9 -veined. Lemma lateral veins without ribs, or ribbed. Lemma surface pubescent; hairy below; inner surface glabrous. Lemma margins eciliate, or ciliolate. Lemma apex dentate; 9 -fid; awned; 9 -awned. Principal lemma awn 2–4 mm long overall; limb ciliate (lower 0.33–0.5 of length). Lateral lemma awns arising on apex of lobes; subequal to principal; ciliate. Palea cartilaginous. Palea keels scaberulous; eciliate; adorned all along. Palea surface glabrous. Rhachilla extension glabrous, or pubescent; hairy at tip. Apical sterile florets 3–4 in number; 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; ellipsoid, or oblong; 1.3–1.8 mm long. Hilum punctiform.
DISTRIBUTION Australasia: Australia.
NOTES Pappophoreae. Kakudidi.
ADDITIONAL CHARACTERS Lemma hairs less than base of awns.
