ERIOCHLOA MOLLIS, Kth.; var. LONGIFOLIA.—Culms 2 to A v 
feet high, slender and branching, leafy; leaves very narrow (2 
lines wide), 1 to 2 feet long; culm and leaves smooth except at 
the nodes; lower sheaths nearly as long as the joints; panicle 
slender, 5 to 8 inches long, of 5 to 8 pedicellate, alternate spikes, 
the lower ones 1% inches long, gradually shorter; general 
rhachis and branches finely. pubescent; the spikes at first erect, 
in fruit nearly horizontal, each with about ten to twelve alternate, 
nearly sessile spikelets, which are rather sparingly appressed- 
pubescent and acute. It differs from the species in its much 
more slender culms, narrower and longer leaves, and in its much 
smaller panicle, with shorter and fewer flowered spikes. 
Collected at Key West, Florida, by A. H. Curtiss. SS 
PANICUM NEALLEYI.—Stem 3 to 4 feet high, stout, simple WV 
or sometimes branched, leafy, smooth; leaves linear-lanceolate, 2 
3 to 10 inches long, 3 to 5 lines wide, thick, smooth, or nearly so, 
rough on the margin, acuminate, striate, slightly hairy at the 
throat and margin of the sheaths; ligule short, membranaceous, 
sheaths mostly shorter than the joints; panicle long peduncled, 
oblong, 5 to 8 inches long, 3 to 4 inches wide, rhachis and 
branches glandular or viscid in spots, the branches single and 
scattered, or somewhat verticillate, much divided and many flow- : 
ered; spikelets purplish, 1 line long, ovate, acutish, sparingly-— 
pubescent, the lower glume broad, hardly one-fourth as long as 
the second and third, which are strongly nine-nerved; flowering as 
glume oblong, acutish. This is closely related to P. viscidum, 
Ell., and is the same as P. scabriusculum of Chapman’s Flora, 
but cannot be the true plant of Elliott, as that is related to P. — 
virgatum. Collected in Texas by Mr. G. C. Nealley. . 
PANICUM REPENS, L.; var. CONFERTUM.—Flowering culms 
about 1 foot high, from thick, creeping, short-jointed root-stalks ; _ 
leaves distichous, rigid, 2 to 3 inches long, spreading; the pan- _ 
icle 1 to 3 inches long, denser than in the type, the branches shorter © 
and the spikelets closer together. Collected in Louisiana by 
A. B. Langlois.
