branous, one-quarter as long as the spikelet or less, ovate or tri- 
angular, I-nerved; second and third scales of equal length, mem- 
branous, more or less pubescent, 7-nerved; fourth scale yellowish 
white, chartaceous, broadly oval, about 1.5 mm. long; palet char- 
taceous, about as long as the fourth scale. 
This grass appears to be confined to Florida, and does not oc- 
cur plentifully. It was found in some abundance by the writer in 
an old muck bed near Eustis, Lake Co., in 1894, No. 1012. The 
plant collected by A. H. Curtiss, No. 3599, and distributed as P. 
microcarpon, belongs here. 
Its affinity is with P. sphaerocarpon EIl., but it is distinguished 
from that species by its longer and erect leaves, the smaller spike- 
lets and the more southern range. 
PANICUM VILLOSISSIMUM nN. sp. 
Whole plant densely villous. Culms 3-6 dm. tall, erect or 
ascending; nodes barbed; sheaths about one-half as long as the 
internodes; ligule a ring of long hairs; leaves linear-lanceolate, 
5-10 cm. long, 4-9 mm. wide, erect, somewhat narrowed toward 
the rounded base, yellowish green, 7—11-nerved; panicle long-ex- 
serted, broadly ovate in outline, 6-10 cm. in length, its branches 
spreading or ascending, somewhat flexuous, the lower ones 3-6 
cm. long; spikelets shorter than their pedicels, elliptic, 2.5 mm. 
long, about 1.25 mm. broad, obtuse or acutish, purplish ; first scale 
membranous, ovate, acute, I-nerved, one-third to one-half as long 
as the spikelet; second and third scales equal in length, mem- 
_ branous, 7-nerved, strongly papillose-villous; fourth scale charta- 
ceous, yellowish white, elliptic, slightly exceeding 2 mm. in length, 
1.25 mm. broad, acutish, somewhat striate; palet chartaceous, 
about as long as the fourth scale. 
A distinct and well-marked species. Collected by Dr. John 
K. Small in the Ocmulgee River swamp, below Macon, May 
- 18-24, 1895. Only the early and more simple state was secured. 
The later and much-branched condition is probably very similar to 
many other forms of the dichotomum group. 
PanicuM WEBBERIANUM DN. sp. 
Whole plant, with the exception of the lowermost sheaths and _ 
the ciliate margins of the upper ones, glabrous, the culms, sheaths 
and leaves often purple. Culms 2-4 dm. tall, erect or ascending, 
rigid, more or less branched, forming moderate-sized clumps; 
sheaths loose, shorter than the internodes; ligule very short, cg
