No. 3. 
PANICUM CiLIATISSIMUM Buckley. 
Rootstock and roots slender. 
Culms varying from erect at the ends of the rootstock to procumbent and even 
creeping, glabrous, except a ring of reflexed hairs at the nodes; erect stems from a 
few inches to 2 feet high, commonly with short sterile branches, slender, the inter- 
nodes sometimes 3 inches long; creeping stems long, thicker, profusely branching, 
with shorter internodes, rooting at the nodes. 
Leaves with long-ciliate, usually sparingly hirsute sheaths, and flat, smooth, or 
sometimes slightly hirsute blades tapering from base to apex. Sheaths of the 
erect stems frequently distant, those of the creeping stems shorter but mostly con- 
tiguous. Blades of the creeping stems seldom exceeding 14 inches, those of the 
erect plants usually longer. 
Inflorescence a small narrow panicle 24 inches long or reduced to a few spike- 
lets, terminating theculm, exsert-stipitate in the erect plant (in creeping plants 
terminating short axillary branches as well, and partly sheathed, all intermediate 
stages being found), bearing the spikelets terminal or laterally sessile on the flat 
minutely pubescent branches of the panicle. 
Spikelets 14 to 2 lines long, oblong, acuminate, slightly obcompressed. 
Glumes 4; 3 lower membranaceous; first lanceolate, acuminate, glabrous, 3- to 
5-nerved, nearly as long as the spikelet; second ovate, short-acuminate, pubescent, 
sometimes minutely villous-ciliate near the margins, many (about 11-)-nerved; third 
similar to the last, but glabrous down the middle, most of the nerves of that area 
obsolete; fourth (flowering) glume coriaceous, indistinctly few-nerved, minutely 
corrugated, bluntly acute. 
Flowers 2. Lower reduced toa hyaline, 2-nerved, oblong palet subtended by the 
third glume; or sometimes with 3 stamens. Upper hermaphrodite; palet of the 
same texture as its a indistinctly 2-nerved; glume closely embracing the 
grain; stamens 3. 
PuaTE III; 1, erect stem; 2, creeping stem; a spikelet opened to show the 
parts. .
