stiff white cilia on the margin near the base: sheaths some- 
what loose, often purplish, the lower less than one-half the 
length of the internodes: ligule none. Panicle 3—7 cm. long, 
broadly oval, the few branches spreading : spikelets 1.5 mm. 
long, obovate, obtuse, contracted at the base, the first scale 
very obtuse, nearly orbicular, about one-third the length of 
the nearly glabrous obtuse second and third. | 
This species is closely related to P. demissum, from eich 
it is separated by having smaller and more numerous spike- 
lets. Collected by me May 20, 1899, growing in dry sand near 
Wilmington, N. C. 
PANICUM ONSLOWENSE nl. sp. A perennial growing in small 
tufts. Stems 2.5-3.5 cm. high, rove or rising from a genicu- 
late base, glabrous. Stem leaves 3-5, 2-4 cm. long, 3-5 mm. 
wide, lanceolate, narrowed at the mas aie upper reduced in 
size, erect or ascending, glabrous except a few short 2-3 mm. 
long cilia on the margin at the base, the edges white and 
roughened: basal leaves much longer and broader, sometimes 
6 cm. long and 1 cm. wide: ligule none: sheaths glabrous, 
sheaths with the leaves shorter than the internodes. Panicle 
broadly ovate, 4-6 cm, long: branches few, fascicled, spread- 
ing very rough: peduncle 1-2 times the length of the panicle: 
spikelets very short—pedicled, elliptic, acute at both ends, 
2-2.5 mm. long, the very thin obtuse first scale one-third to 
one-half the length of the strongly 7—nerved glabrous second 
and third. 
Panicum Onslowense occurs in the flat woods and savannas 
near the coast in the southeastern part of North Carolina and 
.the adjacent parts of South Carolina. It is not uncommon in 
the eastern part of Onslow county, N. C., where the type ma- 
terial was collected near Ward's Mill. It is related to P. 
Nashianum and P, demissum, from both of which it is sepa- 
rated by having acute spikelets and an erect habit. 
PANICUM FILIRAMUM n. sp. A perennial with 2-5 stems 
from the same root. Stems very slender, simple, ascending 
or spreading, at length much branched and reclining, 4-7 dm. 
long, pubescent at least below with short spreading or as- 
cending hairs about 2mm. long. Stem leaves 2-6 cm. long,
