Species

Angiosperms > Poales > Poaceae > Eulalia

Characteristics

Rhizomatous perennial. Culms 40–150 cm high, tufted, branched; base bulbous or slightly swollen, densely covered with sericeous or cream hairs, cataphylls clearly present; nodes glabrous or hairy. Leaves: ligule a jagged edged membrane, 0.5–1.5 mm long; blade 4–30 cm long, 2–4 mm wide. Inflorescences subdigitate or digitate racemes; racemes 2–5 per inflorescence with 12–40 spikelet pairs, 4–10 cm long with dark brown, golden-or caramel-coloured hairs; raceme internodes and pedicels more or less the same length, 2–3.7 mm long, with golden-or caramel-coloured hairs. Spikelets narrowly elliptic, linear or narrowly oblong, 3.5–5 mm long, 0.8–1 mm wide; callus c. 0.5 mm long; lower glume shape and size as per spikelet, very narrowly truncate (sometimes jaggedly so but often obscured by hairs), flat on back, brown, with hairs on lower half of back; upper glume lanceolate, very narrowly truncate, sometimes irregularly notched or obtuse but often obscured by hairs, more or less equal to lower glume in length, brown, sparsely hairy on back; lower lemma absent; upper lemma c. 1.5 mm long (including lobes); awn arising between lemma lobes 9–12 mm long.
More
Perennial; culms slender, 50–150 cm. high, ascending from a tussock or geniculately decumbent to form a mat.. Leaf-blades mostly 3–15 cm. long, 3–6 mm. wide, glabrous, acuminate to a filiform tip; basal sheaths glabrous or silky pubescent.. Inflorescence composed of 2–4(–15) racemes each 3–14 cm. long, villous with rusty brown hairs.. Spikelets narrowly elliptic-oblong, 3.5–4.5 mm. long; lower glume convex on the back with 2–3 faint intercarinal nerves, brown, fulvously pilose, truncate; lower lemma a little square scale or absent; upper lemma bifid for 1/3 its length, with or without a puberulous awn up to 20 mm. long.
Perennial 1000 mm high; rhizomes creeping; culm often decumbent. Leaf blade 30-150 x 3-6 mm; sheath glabrous; ligule a fringed membrane. Inflorescence of 2-3(5) racemes, hairs golden-brown. Sessile and pedicellate spikelets alike, 3.5-4.0 mm long, densely hairy, usually 1-flowered; glumes ± equal; lower glume convex on back, keel with long scattered hairs; upper lemma awn 7-12 mm long, awn almost twisted throughout, usually strongly geniculate, hairy; anther 2.5-3.0 mm long.
Perennial, creeping rhizomatous, up to 1 m high. Leaf blades 30-150 mm long, 3-6 mm wide. Culms often decumbent; sheaths glabrous. Spikelets 3.5-4.0 mm long (sessile and pedicellate alike). Raceme hairs golden-brown.
