dum Yam., and is the P. nitidum of Dr. Chapman’s Southern Flora. It 
is also probably the P. microcarpon of Elliott. It occurs along the coast 
as far north as eastern Virginia. As it is variable in the amount of 
pubescence, some specimens being quite glabrous, and others hav- 
ing the stems and sheaths pubescent, and nodes barbed, ‘it is possible 
that Elliott may have based his P. mtcrocarpon on specimens of 
the pubescent form. Virginia: Curtiss; Bedford Co., 1873, sub nom. 
P. nodiflorum Tam. North Carolina: Ashe; Wilmington, 1895. 
Florida: Chapman; Apalachicola. Curtiss, Jacksonville, No, 4033. 
47) PANICUM LEUCOTHRIX Nash, Torr, Bul. 24:41 
(1817). Stems somewhat tufted, slender, 12’—30’ tall, 
glabrous, or pubescent below. Sheaths shorter than the 
internodes, glabrous or the lower pubescent ; ligule pil- 
ose. Leaves lanceolate,13’ long or less, 1”—-2”’ wide, nar- 
rowed to the base, spreading or ascending. Panicle ob- 
long, }’—13’ long, the numerous short fascicled branches 
ascending ; spikelets very numerous, less than $’’ long, 
spheroid, whitish or purple. 
Central Florida to North Carolina near the coast. Florida: Curtiss; 
Jacksonville, 5912. North Carolina: Ashe; Manteo, June, 1898. Re- 
ated to P. parvispiculatum. This is Elliott’s P, nttidum. 
48) Panicum Eatont Nash, Torr. Bul. 25: 84 
(1898). Erect, 1’--3’ tall, glabrous. Sheaths smooth: 
ligule pilose. Leaves lanceolate, taper-pointed, ascend- 
ing, becoming much smaller towards top of culm, the 
largest 3’--4’ long, and 4”--5” wide: panicle long-pe- 
duncled, oblong, 3’--5’ long, the numerous short branch- 
es ascending ; spikelets oval, about 7%” long, first scale 
about one-third as long as the pubescent, 7-uerved sec- 
ond and third.

49) Panicum ColUBIANUM Scribn. Bul. U.S. Div. 
of Agrost. 7: 78 (1897). Stems somewhat tufted, 8-20’ 
high, strict, glabrous or the lower pubescent: ligule 
pilose. Leaves distant, ascending, lanceolate, taper- 
pointed, the upper reduced in size, largest 2’--3’ long,
