Panicum sendulskyi
HABIT Annual. Culms rambling; 50–100 cm long. Culm-internodes terete; 2.5–9 cm long; distally glabrous. Culm-nodes pallid; glabrous, or pubescent. Lateral branches ample; arising from lower culm. Leaf-sheaths mostly shorter than adjacent culm internode; glabrous on surface; outer margin hairy. Ligule a ciliate membrane; 0.4–0.8 mm long. Collar glabrous, or pubescent. Leaf-blade base broadly rounded. Leaf-blades linear; 2.5–9 cm long; 3–6 mm wide. Leaf-blade surface glabrous. Leaf-blade margins scaberulous; ciliate; hairy at base. Leaf-blade apex attenuate.
INFLORESCENCE Inflorescence a panicle; terminal and axillary. Peduncle 15–25 cm long; glabrous.
Panicle open; pyramidal; effuse; 3–8 cm long; 2.5–7 cm wide. Panicle branches glabrous; glabrous in axils, or pubescent in axils.
Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform; 1.5–5 mm long; glabrous.
FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; 2.8–3.2 mm long; 1 mm wide; falling entire.
GLUMES Glumes dissimilar; reaching apex of florets; thinner than fertile lemma. Lower glume ovate; not clasping; 1.8–2 mm long; 0.66 length of spikelet; membranous; without keels; 1–3 -veined. Lower glume lateral veins absent, or obscure. Lower glume apex acute. Upper glume ovate; 1 length of spikelet; membranous; without keels; 9 -veined. Upper glume lateral veins prominent. Upper glume apex acute.
FLORETS Basal sterile florets barren; with palea. Lemma of lower sterile floret similar to upper glume; ovate; 1 length of spikelet; membranous; 9 -veined; prominently veined; acute. Palea of lower sterile floret 2.2–2.4 mm long. Fertile lemma elliptic; dorsally compressed; 2–2.4 mm long; 0.7–0.8 mm wide; indurate; pallid; without keel. Lemma surface papillose. Lemma margins involute. Lemma apex with a little green crest and pubescent. Palea involute; indurate.
FLOWER Lodicules 2; 0.3 mm long; truncate. Anthers 3; 0.6–1 mm long.
FRUIT Caryopsis with adherent pericarp.
DISTRIBUTION South America: Brazil.
