siderably larger, and the primary panicle branches not remaining 
contracted, but spreading at once. 
As this grass is apparently quite common, there may be an 
older name than the above, but up to the present search has 
failed to reveal it. When a proper disposition is made of the 
species of Elliott and Michaux, and some of the other early 
southern botanists, some name among them may be found to 
apply to this plant. There can be no doubt, however, as to this 
grass being the P. xewranthum of Grisebach, for, as stated above, 
it exactly matches the form upon which he based the species. 
PANICUM ANGUSTIFOLIUM Ell. Bot. S. C. & Ga. 1: 129. 1817. 
P. neuranthum var. ramosum Griseb. Cat. Pl. Cub. 232. 1866. 
As stated above, this appears to be clearly distinct from P. 
neuranthum Grisebach. The specimen on which Grisebach based 
his variety ramosum, no. 3454 of Wright’s Cuban Collection, 
matches the late and much branched condition of Elliott’s P. an- 
gustifolium, well represented by Curtiss’ nos. 4028 and 4678. In 
addition to those cited already, I would refer the following to this 
species :

‘PANICUM POLYCAULON n. sp. 
Plant yellowish green, with the habit of P. ciliatum EIl., — 
smooth and glabrous, excepting the margins of the sheaths and 
leaves, and the axis of the panicle which is sparingly pilose. 
Culms densely caespitose, the upper portion naked, 2 dm. tall or 
less, erect, simple, or at length somewhat branched; sheaths 
coarsely striate, ciliate on their margins, the lower loose, 2.5 cm. 
long or less, the uppermost one longer than the remainder; 
ligule a ring of very short hairs; leaves erect or ascending, nar- 
rowly oblong-lanceolate, 2-7 cm. long, 2-8 mm. wide, somewhat 
narrowed toward the rounded base, acuminate at the apex, ciliate _
