showed excellent specific characters. I find that I have 
collected the plant at two stations, both in Orange 
county, N.C. 
PANICUM ORANGENSIS, sp. nov. Stems 12 to 24 
inches long, ascending from a geniculate base, pubescent 
with long, soft, white, matted hairs, but more or less 
glabrate towards the top. Lower sheaths crowded and 
overlapping, pubescent with soft matted hairs; the upper 
distantand nearly glabrous. Leaves soft-pubescent like | 
the sheaths, the largest 3 to 4 inches long and 3” to 5”’ 
wide, lanceolate, long taper-pointed, largest near the base 
of the stem ; the upper much reduced and often glabrous. 
Ligule pilose with long hairs. Panicle long-peduncied, 
oblong, the very numerous, slender fascicled branches 
ascending ; spikelets scarcely }’’ long, obovate, apiculate, 
the first scale about.one-third as long as the glabrous 7- 
nerved second and third. 
Related to Panicum lanuginosum Ell., and separated from it by hay- 
ing a longer, softer pubescence and its leaves not being ciliate. Col- 
lected in June, 1898. 
As the name Panicum commelinaefolium proposed by me (Mitchell 
Journ. 15, part 1; 29) for a Georgia plant has already been used by 
Kunth for another grass, I propose the name Panicum Currant for my 
plant ; and for Panicum Georgianum Ashe (ibid, 36) I propose the name 
Panicum Cahoonianum, since Sprengel has made use of the nearly sim- 
ilar P. Georgicum for a different plant. 
ANDROPOGON GYRANS sp. nov. Stem very slender, 18 
to 24 inches high, glabrous or merely bearded at the up- 
per joints. Basal leaves 10 to 14 inches iong, 1’’ wide or 
less, glabrous, often involute and twisted, those of the 
stem much shorter. Sheaths glabrous. Branches very 
few, scarcely protruding from the closely wrapped 
sheaths. Spikes 2 or 4, generally 4, very slender, 6 to 
12 flowered, spikelets 13’’ long, shorter than the copious, 
white, basal hairs ; sterile spikelets of single scale, cov-
