leaves, glabrous above, and the larger more open panicle readily 
separate this from P. malacon, which is described below. 
I was at first inclined to consider this the P. ovale of Elliott, 
but after a careful comparison with the description and with a 
specimen so named by Elliott, I feel justified in the above disposi- 
tion of it. 
PANICUM GLABRIFOLIUM N. sp. 
Whole plant, except just below the lower nodes, smooth and 
glabrous and somewhat shining, especially the panicle and spike- 
lets. Culms caespitose, 1.5-4 dm. tall, erect, rigid, slender, leafy 
to the top, the longer culms pubescent for a greater or less dis- 
tance below the lower nodes, at length somewhat branched ; nodes 
purplish, the lower ones generally upwardly barbed; sheaths 
strongly striate, the lowermost ones pubescent, particularly at the 
base, 3 cm. long or less, closely embracing the culm, a tuft of 
hairs on each margin at the apex; ligule a fringe of hairs .5 mm. 
long; leaves narrowly linear, 7-9-nerved, erect, rigid, thickish, 
long acuminate, narrowed toward the base, those on the sterile 
shoots 15 cm. long or less, 3-4 mm. wide, those on the fruiting 
culms 3-9 cm. long, 1-3 mm. wide; panicle ovate, 4-6 cm. long, 
3-4 cm. wide, its branches spreading or somewhat ascending, sin- 
gle, the longer branches about 2 cm. long, bearing 3 or 4 distant 
ultimate divergent divisions which are 2-6 times as long as the 
spikelets; spikelets slightly exceeding .5 mm. in length, tinged 
with purple, obovate, the first scale less than one-half the length 
- of the spikelet, membranous, orbicular-ovate, obtuse, I-nerved, the 
second and third scales broadly oval, membranous, 5—7-nerved, 
the latter enclosing a hyaline palet one-half its length, the fourth — 
scale oval, chartaceous, white, enclosing a palet of equal length 
and similar texture. 
Collected by the writer in the “ flatwoods” at Tampa, Florida, 
on August 20, 1895,no. 2415a. It grows in dense tufts, the long 
narrow erect leaves and the wiry culms giving it a striking ap- 
pearance. 
/ Panicum LINDHEIMERI n, sp. 
Whole plant, with the exception of the lower sheaths, usually 
the lower internodes, and the spikelets, smooth and glabrous. 
Culms slender, erect, at length branched, the lower internodes 
sparingly papillose-hirsute, or sometimes glabrous; nodes often 
barbed with spreading or somewhat reflexed hairs; sheaths shorter 
than the internodes, somewhat loosely embracing the culms, ciliate _ 
on the margins, the lower ones sparingly papillose-hirsute; ligule _ 
a fringe of hairs about 2 mm. long; leaves ascending, 2-7 cm. long, |
