bescence is much more rigid, the culm and panicle glabrous, or 
rarely with a few scattered hairs, and the leaves and spikelets 
glabrous, or the latter occasionally somewhat pubescent with 
shorter hairs. 
Dr. Palmer’s no. 382, collected probably in the same locality 
as his no. 383, referred to above, is P. Scribnerianum, and strik- 
ingly shows the differences, already noted above, between this and 
P. malacophyllum, when growing in the same region. 
PANICUM NEURANTHUM Grisebach, Cat. Pl. Cub. 232. 1866. 
There is no doubt as to the occurrence of this species in the 
United States, its range extending, so far as the specimens to 
which I have had access indicate, from southeastern Virginia, thus 
bringing it into the region covered by the Illustrated Flora, to 
Florida, and westward to Louisiana. 
Grisebach based his species on Wright’s Cuban Collection no. 
3453. This exactly matches the plant collected by A. H. Curtiss, 
in Duval Co., Florida, no. 3567*, and also my no. 1243, secured 
at Eustis, in the same State, during July, 1894. 
I would refer to this species, in addition to those already cited 
above, the following : 
N. L. Britton, Virginia Beach, Va., Sept. 10, 1895. 
Ravenal, Aiken, S. C., May 28,1867. 
J. K. Small, near Valdosta, Lowndes Co., Ga., June 6-12, 1895. 
J. H. Simpson, Sanibel Island, Fla., March, 1891, no. 298. 
Chapman, Appalachicola, Fla. 
S. M. Tracy, Ocean Springs, Miss., Aug. 3, 1889, no. 421. 
C. L. Pollard, Biloxi, Miss., July I, 1895, no. 1417. 
Drummond, New Orleans, 1832. 
Curtiss’ plant, and also my own, both cited above, well repre- 
. 
sent the late and much branched state, while Simpson’s no. 298, © 3 
and the plant collected by Ravenal, both also alluded to ‘above, oe 
Present the state of the plant in its early and simple condition. 
This is closely related to P. angustifolium Ell., a specimen aie 
which, so named by Elliott, is in the herbarium of Columbia Vee : 
versity. The smaller obtuse spikelets which are broader in pro- 
Portion to their length and the branches of the primary panicle re- 
Maining contracted for some time readily separate it from the . P. 
eons EIL, in which he esate bask agate
