Panicum fischeri

HABIT Perennial. Culms 50–100 cm long. Ligule a fringe of hairs. Leaf-blades 15–30 cm long; 4–8 mm wide. Leaf-blade apex attenuate.

INFLORESCENCE Inflorescence a panicle.

Panicle open; ovate; 15–30 cm long; 10–25 cm wide. Primary panicle branches whorled at most nodes; 8–15 cm long. Panicle branches scaberulous; glabrous in axils; with insignificant pulvini.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels scaberulous.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; with a barren rhachilla extension. Spikelets elliptic; dorsally compressed; compressed slightly; 5 mm long; falling entire.

GLUMES Glumes similar; reaching apex of florets; thinner than fertile lemma. Lower glume ovate; 2.5–3 mm long; 0.5–0.66 length of spikelet; membranous; without keels; 5 -veined. Lower glume apex acute. Upper glume elliptic; 1 length of spikelet; membranous; without keels; 9 -veined. Upper glume apex acute.

FLORETS Basal sterile florets barren; with palea. Lemma of lower sterile floret similar to upper glume; elliptic; 1 length of spikelet; membranous; 9 -veined; acute. Fertile lemma elliptic; dorsally compressed; 3.5 mm long; coriaceous; yellow; shiny; without keel. Lemma margins involute. Lemma apex obtuse. Palea involute; coriaceous. Rhachilla extension 3.5 mm long.
