ways between P. arenicolum and P. neuranthum. 'The very 
long narrow stem leaves and the pubescence of the plant are 
distinctive, however. 
PANICUM ORTHOPHYLLUM n. sp. A somewhat tufted peren- 
nial. Stems strict, erect, glabrous, or pubescent with ascend- 
ing hairs, 4-6 dm. high, primary stem leaves somewhat nar- 
rowed to the base, erect, glabrous or nearly so, 5-8 cm. long, 
3-5 mm. wide: sheaths appressed pubescent or glabrous with 
a few cilia nearthe throat, shorter than the internodes, or 
the later crowded and overlapping: secondary leaves much 
narrower : ligule a ring of hairs 1-2 mm. long: basal leaves 
few, much shorter and broader. Panicle long-peduncled, 
ovate, the few branches erect, ascending or spreading, glab- 
rous : spikelets barely 2 mm. long, broadly obovate, very ob- 
tuse, first scale small, obtuse, about one-fourth the length of 
the sparingly pubescent strongiy 7-nerved second and third. 
Shady slopes of sand hills, New Hanover county, N. C, 
June 1899. Related to P. angustifolium and P. neuranthum, 
from which separated by having smaller obovate spike- 
lets. 
PANICUM ERYTHROCARPON 1. sp. A somewhat tufted peren- 
nial. Stem stout, erect, 4-6 dm. high, pubescent, at least be- 
low, with soft appressed or ascending hairs. Primary stem- 
leaves spreading or erect, 4-7 cm. long, 4-8 mm. wide, lanceo- 
late, rounded or narrowed at the base, long taper-pointed, 
pubescent on both sides with appressed hairs, often mixed 
with long spreading hairs towards the base on the upper side, 
margins ciliate at the base: ligule pilose: sheaths appressed 
pubescent, often nearly as long as the internodes. Panicle 
7--12cm. long, 6-14 cm. wide, ona peduncle of about its length, 
the numerous fascicled branches spreading or drooping. 
Spikelets 2.5-3 mm. long, elliptic, acute, generally bright 
red, the first scale very acute, nearly one half as long as the 
pubescent 7-nerved second and third. 
This plant is separated from P. pubescens, which it resem- 
bles, by having larger spikelets and ascending pubescence, 
and from P. haemacar pon by having larger spikelets, a more 
ample panicle, and guuch greater size.
