2-4 mm. wide, the upper very short, rather thin, narrowed at 
the base, ascending, pubescent especially on the lower surface 
and towards the base with spreading hairs, or glabrous: lig- 
ule villous with white hairs 3 mm. long: sheaths pubescent 
with spreading or ascending hairs 1-2 mm. long, especially at 
the throat: nodes barbed: basal leaves glabrate, much broad- 
_ er and shorter than the lower stem leaves. Panicle 4-6 dm. 
long, oval, the branches horizontal, glabrous: spikelets nu- 
merous, on very slender spreading pedicels, broadly obovate, 
1.5mm. long, first scale very obtuse, about one-third the 
length of the pubescent 5-7 nerved second and third. 
This species is related to P. arenicolum and P. arenicolordes, 
but is separated from both by having very much smaller spike- 
lets. Habitat: sandy woods, eastern North Carolina. Type 
material collected in New Hanover county, N. C., in June

PANICUM ARENICOLOIDES nl. sp. A perennial with 2-5 stems 
from the same root. Stems very slender, simple, ascending 
from a geniculate base, or at length much branched and 
spreading, 4-7 dm. long, pubescent, at least below, with 3-4 
mm. long spreading white hairs, or merely puberulent, glab- 
rateabove. Stem leaves 5-8, spreading or ascending, 4-1lcm. 
long, 2-4 mm. wide, narrowed at the base, pubescent, espe- 
cially near the base, with 3-4 mm. long spreading white hairs, 
or glabrate, the longest one-third above base of stem, upper 
much narrowed and shorter: basal leaves much broader and 
shorter: ligule of dense white hairs about 1 mm. long: 
sheaths one-third toone-half the length of the internodes, 
which are generally somewhat longer than the leaves, pubes 
cent, especially the lower, or glabrate. Panicle 5-7 cm. long, 
2-5cm. wide, the rather few flexuous branches erect or as- 
cending : spikelets obovate, 2—2.2 mm. long, abruptly acute, 
contracted at the base, first scale acute, one-third the length 
of the strongly 7-nerved very pubescent second and third: pe- 
duncle about the length of the panicle. 
Habitat: shady sandy woods along the coast of North Car- 
olina. Type material collected by me near Wilmington, 
N. C., June 6, 1899. This species is intermediate in many
