Panicum fauriei

HABIT Annual; caespitose. Culms 2–30(–46) cm long. Culm-internodes distally pubescent. Culm-nodes pubescent. Lateral branches sparse. Leaves cauline. Leaf-sheaths puberulous. Leaf-sheath oral hairs ciliate; 1–2.5 mm long. Ligule a ciliate membrane; 0.4–1.6 mm long. Leaf-blades flat, or involute; 1.5–12 cm long; 1–4 mm wide. Leaf-blade surface pilose; hairy adaxially (puberulous below).

INFLORESCENCE Inflorescence a panicle.

Panicle open; linear; 1–11 cm long. Primary panicle branches appressed. Panicle axis with scattered hairs, or puberulous. Panicle branches puberulous, or pilose.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; acute, or acuminate; 1.5–4.2 mm long; falling entire.

GLUMES Glumes reaching apex of florets; thinner than fertile lemma. Lower glume ovate; 1 length of spikelet; membranous; without keels; 3–5 -veined. Lower glume surface glabrous, or pubescent; without hair tufts, or with an apical beard. Lower glume hairs 0.6–3.5 mm long. Lower glume apex acute, or acuminate. Upper glume elliptic; 1 length of spikelet; membranous; without keels; 5–9 -veined. Upper glume surface glabrous, or pubescent; without hair tufts, or with an apical beard. Upper glume hairs 0.6–3.5 mm long. Upper glume apex acute, or acuminate.

FLORETS Basal sterile florets barren; with palea. Lemma of lower sterile floret similar to upper glume; elliptic; 1 length of spikelet; membranous; 7 -veined; glabrous, or pubescent; hairy above; acute. Palea of lower sterile floret 0.15–0.2 length of lemma. Fertile lemma elliptic; dorsally compressed; 1.2–1.8 mm long; indurate; dark brown; shiny; without keel. Lemma margins involute. Lemma apex acute. Palea involute; indurate.

FLOWER Anthers 3; 0.8–1.1 mm long.

FRUIT Caryopsis with adherent pericarp.

DISTRIBUTION Pacific: north-central.

NOTES Paniceae. Wagner 1993.
