Hackel, but I think its affinity is clearly with Trisetum. Very nearly 
the same structure of flowers occurs in T. palustre. 
Leptochloa Langloisil — Culm smooth, stout, leafy, 3 to 4 ft. ^ 
high, the radical leaves one-third as long as the culm, loosely sheath- 
ing the base of the culm, joints or nodes 7 or 8, the sheaths com- 
pressed, striate, loose, rather glaucous, the leaves a foot long, 3 to 4 
lines wide, keeled, somewhat scabrous, the upper one sheathing the 
base of the panicle; panicle racemose, 10-12 inches long, 2 inches 
wide, loose, erect or nodding above, the simple branches very numer- 
ous (100 or more), crowded below, erect-spreading, irregular on the 
axis, singly or 2-3 together, 2 to 3 inches long, mostly less than half 
an inch apart, flower-bearing throughout; spikelets 3-4-flowered, ses- 
sile and imbricated, about one and a half lines long; outer glumes 
unequal, membranaceous, ovate-lanceolate, acute, slightly scabrous 
on the keel, the lower about half a line, the upper about one line 
'ong; flowering-glumes little more than one line, lanceolate, acute or 
short-mucronate, 3-nerved, slightly pubescent on the keel, and ciliate 
on the marginal nerves below; palet a little shorter, bidentate. 
This larp;e and showy species was found in Louisiana by Rev. A. 
B. Langlois, for whom it is named. 
Leptochloa Nealleyi. — Cuhns 2 to 2.5 ft. high, and, with the 
sheaths, smooth, with about three nodes; leaves 6-10 inches long, 
2-3 lines wide, the sheaths loose and striate, the upper one long and 
sheathing the base of the panicle; panicle 8-10 inches long, narrow, 
the simple branches about one inch long, in threes or fives, or partly 
scattered, closely flowered; spikelets small (little more than a line 
'•^"g), 3-5-flowered; outer glumes unequal, ovate, acutish, thick and 
green on the keel, the lower, half as long; iflowering-glames .5 to .75 
line long, 3-nerved, oblong, sparsely pubescent on the nerves, the 
apex emarginate, obtuse and finely denticulate; palet narrow, as long 
as the flowering-ghime, 2-keeled, finely pubescent on the keels. 
Collected in Texas by Mr. G. C. Nealley, for whom it is named. 
Probably this and the preceding have been collected before, but so 
far as I know have not previously been named.

. CvpERus PraNGLEi, «. x/).— Culm upright, about 2 ft. high, sharply 
triangular. Leaves smooth, except the scabrous margins, 8-12 inches

more prominent. Spikelets 1.5-2 lines long, of 3 or 4, acute, ovate 
to ovate-lanceolate, 9-11-nerved scales, a single one fertile m each,
