Two New Florida Plants. 
* The sets of plants collected in South Florida by the late Dr. 
A. P. Garber, and distributed by him, could not have been all 
alike, for I find in mine the two following species, not before re- 
ported, so far as I know: 
1. Jussi@a acuminata, Swz. It was labelled “ Ludwigia 
cylindrica, Ell? Manatee, S. Fla., Dec., 1877,, Coll. A. P. 
Garber, M.D.” Laid aside for further examination, I took it 
up a few weeks ago, and made it out by the aid of Grisebach’s 
Flora. By request, Dr. Britton has compared it with No. 2,559 
of Wright’s Cuba Collection, and says it is exactly the same. 
2. Sponia micrantha, Decaisne. (DG. Prod. “xvi. p203; 
var. D.) Miami, S. Fla, June-July, 1877. Coll. A. P. Garber, 
M.D. It was numbered 229, and without name. A brief note 
of Dr. G. calls it “a shrub, six or eight feet high, with small, red 
berries.” In the West Indies it is said to attain the height of a 
good-sized tree. TuHos. C. PORTER, Easton, Pa.

SPOROBOLUS SHEPHERDI. Culms 10 to 12 inches high, 
much branched at the base, smooth ; leaves 2 to 3 inches long, 
narrow and acuminate, becoming involute, the lower sheaths 
loose, inflated, striate, short, the upper one twice or thrice as 
long; ligule conspicuous, toothed at the apex; panicle about 4 
inches long, 1 to 2 inches wide, open, the branches mostly scat- 
tered or semi-verticillate, rather erect, slender, subdivided nearly 
to the base, the branchlets and pedicels long, the latter capillary 
and flexuous, thickened above; spikelets less than 1 line long, 
smooth; empty glumes ovate, acutish, a little shorter than the 
spikelet, thin, not keeled nor nerved ; flowering glume ovate, 
faintly three-nerved, thicker than the outer glumes, sparingly 
hairy externally ; palet nearly as long as its glume and of the 
same texture. Apparently annual, 
A pretty grass, conspicuous for the silvery hue of the spike- 
lets. The panicle has the aspect of S. ramulosus, but is much
