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. Scribneriamiin , and strik- 

 ingly shows the differences, already noted above, between this and 

 P. malacophylliim , when growing in the same region. 



Panicum neuranthum Grisebach, Cat. PI. 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, 

 and the plant collected by Ravenal, both also alluded to above, 

 present the state of the plant in its early and simple condition. 



This is closely related to P. aiignstifolinui Ell., a specimen of 

 which, so named by Elliott, is in the herbarium of Columbia Uni- 

 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. 

 ajigiistifoliuvi Ell., in which the spikelets are acute and con-
