Paspalum giuliettiae

HABIT Perennial. Rhizomes short. Culms 30 cm long; 0.8–1.7 mm diam. Culm-internodes distally glabrous. Leaf-sheaths striately veined; pubescent; outer margin hairy. Ligule an eciliate membrane; 0.25–0.5 mm long; brown. Leaf-blades linear, or lanceolate; 3–15 cm long; 4–6 mm wide. Leaf-blade surface glabrous. Leaf-blade margins ciliate; hairy at base. Leaf-blade apex acute.

INFLORESCENCE Inflorescence composed of racemes. Peduncle 11–14 cm long.

Racemes (1–)2; single, or borne along a central axis; sinuous; unilateral; 2–5 cm long; 0.7–0.8 mm wide. Central inflorescence axis 0.6–1 cm long. Rhachis narrowly winged; angular; scabrous on surface; smooth on margins. Spikelet packing abaxial; 2 -rowed. Raceme-bases pubescent; hairy in axils.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels 0.6 mm long; scaberulous.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic, or obovate; dorsally compressed; plano-convex; obtuse; 1.2–1.9 mm long; 1–1.2 mm wide; falling entire.

GLUMES Glumes one the lower absent or obscure; reaching apex of florets; thinner than fertile lemma. Upper glume ovate; 1.7–1.9 mm long; 1 length of spikelet; membranous; without keels; 4–5 -veined. Upper glume primary vein absent, or obscure. Upper glume lateral veins parallel at apex. Upper glume surface glabrous.

FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret similar to upper glume; elliptic; 1.7–1.9 mm long; 1 length of spikelet; membranous; 4–5 -veined; without midvein, or with obscure midvein. Fertile lemma elliptic, or ovate; dorsally compressed; 1.6–1.7 mm long; indurate; yellow, or light green; without keel. Lemma surface papillose. Lemma margins involute. Palea involute; indurate.

FRUIT Caryopsis with adherent pericarp; obovoid; 1 mm long.

DISTRIBUTION South America: Brazil.
