Panicum ALBEMARLENSE nl. sp. <A densely tufted peren- 
nial, dark green or purplish in color, 2-3 dm. high. Culms 
erect, strict, slender, villous with spreading or ascending 3-4 
mm. long white hairs, leafy to near the top, barbed at the 
nodes: internodes much longer than the leaves and sheaths. 
Stem-leaves 3-5, firm, erect, 2-5 cm. long, 3-4 mm. wide, the 
longest near the middle of the stem, very gradually tapering 
to the apex from near the rounded base, pubescent above with 
long spreading white hairs, especially towards the base, 
mixed with shorter ones, pubescent beneath with short as- 
cending hairs, the margins very rough and ciliate at the base 
with a few long hairs: ligule of a few 2 mm. long hairs ; 
basal leaves 1-2 cm. long, 4-7 mm. wide, glabrate, at least 
when old. Primary panicle 2-4cm. long, 1.5-3 cm. wide, the 
numerous branches ascending, on a short peduncle, 1-4 cm. 
long, or barely exserted: spikelets broadly obovate, 1.5 mm. 
long, 1.2 mm, wide, first scale acute, one-third the length of 
the strongly 7—9-nerved second and third scales, which are 
pubescent with spreading hairs. 
PANnicuM ALBEMARLENSE is very common in well drained 
open woods in Beaufort and Hyde counties, N. C., where the 
type material was collected by me May 26, 1899, near Scran- 
ton. It has the same habit and is closely related in character 
to P. meridionale Ashe, from which separated by being larger, 
having shorter pubescence, and larger spikelets. 
I find that there has been previous use of a very similar 
name or of the same name which I have applied to the three 
following species of Panicum,” so I propose the following 
changes in their names: 
PANICUM SHALLOTTE n. nom. FP. glabrisstmum Ashe, not 
P. glaberrimum Steud.
