Collected on granitic rocks, Llano Co., Texas, by Mr. J. 
Reverchon. 
GLYCERIA LEMMONI.—In the Botanical Gazette for January, 
1878, I published this species as Poa Lemmoni. It must now — 
fall into Glyceria, section Atropis, and hence the above name. It 
is a very distinct species and has since been collected by Mr. M. 
E. Jones in Nevada, and in Oregon by Mr. T. Howell. 
FESTUCA TEXANA.—Culms 2 to 2% feet high, rather stout, JS 
smooth; leaves rather numerous below with loose sheaths, 
only two or three above with long smooth sheaths, and linear- 
acuminate erect blades, 4 to 8 inches long, and I to 2 
lines wide; ligule wanting; panicle pyramidal, about 6 inches 
long, the branches erect-spreading, in pairs below, single above, 
somewhat distant, the lower ones 3 to 4 inches long, divided 
above the middle, few-flowered, pedicels nearly as long as 
the spikelets to twice as long; spikelets light green and 
glaucous, three to five-flowered, about 4 lines long; empty 
glumes linear-lanceolate, acute, rigid, smooth except on the 
midrib, the lower one nearly 2 lines long, one-nerved, the 
upper one ¥% longer, three-nerved; flowering glumes ovate- 
lanceolate, acute, mucronate or short-awned, smooth, rigid, about 
3 lines long, indistinctly five-nerved, finely punctulate; palet 
equaling its glume and as firm in texture, terminating with two 
fine teeth. cam 
ELymMus MAcountt.—Several years ago I received from Mr. ¥ 
J. Macoun an Elymus collected in the Great Plains of British 
America which I called by the above name, but no account of it 
was published. I have several times since received it from 
within the limits of the United States, and two years ago myself 
collected it freely in the mountains of Colorado. The specimens 
from different localities show considerable variation, but Iam not 
able to separate them specifically. It is the smallest of our 
species, and in reduced forms has much the appearance of 
Hordeum pratense. It may be described as follows: 
Culms 2 to 3 feet high, smooth, leaves of culm 3 or 4, 
rigid, erect, narrow, scabrous, 3 to 6 inches long; ligule 
short and truncate; spike slender, erect, cylindrical, 3 to 
5 inches long; commonly in slender specimens there is but
