Panicum palmifolium J. König, Naturforscher. 23: 208. 1788.
Perennials; clums caespitose, 60-100 cm tall, with short rhizome. Blade lanceolate, pubescent
below, to 40 cm long, to 6.5 cm wide, plicate; sheath keeled, papillose-hispid; ligule a ring of hairs, 1.5-
2 mm long. Panicle loose, as much as 40 cm long, spikelets crowded, branches extending into bristles of
5-15 mm long; main axis nearly glabrous. Spikelets 3-4 mm long, lanceolate, acute; glumes and lower
lemma with margins hyaline; lower glume 3-5-veined, ovate, 1/3-1/2 as long as spikelet; upper glume
ovate, 5-7-veined, 1/2 to as long as spikelet; lower lemma 5-veined, acuminate, with a short incurved
point, enclosing a hyaline lower palea; upper lemma ovate, faintly and transversely rugose, mucronate,
shiny; anther ca.1.4 mm long.
