Whiteochloa multiciliata
HABIT Annual; caespitose. Culms 45–75 cm long; 4–6 -noded. Culm-internodes channelled. Culm-nodes glabrous. Leaf-sheaths glabrous on surface, or pilose, or hirsute; with tubercle-based hairs; outer margin hairy. Ligule a ciliolate membrane; 0.5 mm long. Leaf-blades 10–17.7 cm long; 3–5.5 mm wide. Leaf-blade surface smooth, or scaberulous; glabrous, or hispid; with tubercle-based hairs. Leaf-blade margins cartilaginous; scabrous; glabrous, or tuberculate-ciliate; hairy at base.
INFLORESCENCE Inflorescence a panicle. Peduncle glabrous.
Panicle open; ovate; 14–18 cm long; 5–10 cm wide. Primary panicle branches 7–14 cm long.
Spikelets solitary. Fertile spikelets pedicelled. Pedicels 1–9 mm long.
FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; laterally compressed; compressed slightly; 2.5–3.5 mm long; falling entire. Rhachilla internodes elongated below proximal fertile floret. Rhachilla elongation slender.
GLUMES Glumes dissimilar; reaching apex of florets; thinner than fertile lemma. Lower glume oblate; 1 mm long; 0.25–0.4 length of spikelet; membranous; 1-keeled; 3 -veined. Lower glume surface smooth, or scabrous; glabrous, or hispid; hairy on veins. Lower glume apex acute. Upper glume oblong; 1 length of spikelet; membranous; without keels; keel-less except near apex; 7 -veined. Upper glume lateral veins ribbed. Upper glume surface smooth, or asperulous; hispid; hairy on veins; with tubercle-based hairs. Upper glume margins tuberculate; ciliate. Upper glume apex acuminate.
FLORETS Basal sterile florets male; with palea. Lemma of lower sterile floret similar to upper glume; ovate; 1 length of spikelet; scarious; 5 -veined; sulcate; scaberulous; rough above; glabrous, or hispid; hairy on veins; obtuse. Fertile lemma elliptic; dorsally compressed; 1.5–2 mm long; indurate; shiny; without keel. Lemma margins involute. Lemma apex acute. Palea indurate.
FLOWER Anthers 3.
FRUIT Caryopsis with adherent pericarp; ellipsoid; 1.5 mm long; light brown.
DISTRIBUTION Australasia: Australia.
NOTES Paniceae. Lazarides 1993.
