glumes narrow, acute, purplish, the lower 4 lines, the upper 
5 to 5% lines long; flowering glume as long as the upper empty 
glume, or slightly longer; awns about equal, 7 to 8 lines long, 
spreading. Differs from A. purpurea, Nutt., in the narrower, 
denser panicle, with sessile branches, smaller flowers and shorter 
awns. Collected by Reverchon on rocky hills in Crocket County, 
Texas. 
StipA LETTERMANI, V.—Culms 1 to 2 feet high, slender; 
radical leaves filiform, 4 to 6 inches long; ligule short; panicle 
spike-like, narrow, slender, 4 to 6 inches long, loose; lower rays 
I to 1% inches long, erect, mostly single, sparsely flowering 
nearly to the base, upper branches shorter; outer glumes about 
3 lines long, acuminate and awn pointed, both three-nerved; flow- 
ering glume about 2 lines long, sparsely pubescent, the hairs long 
near the summit, awn bent, 6 to 8 lineslong. One of the smallest 
flowered species; collected in Idaho by Prof. G. W. Letterman. 
MUHLENBERGIA PARISHU, V.—This species was described 
in the Bot. Gazette, for August and September, 1882, page 93, as 
MM. sylvatica, var. Californica. 1am now satisfied that it is a good’ 
species and name it for the collector, Mr. S. B. Parish, of San 
Bernardino. Cal. pe 
MUHLENBERGIA CALIFORNICA, V.—This was described, on | 
page 92 of the same number of the Bot. Gazette, as JZ. glomerata, 
var. brevifolia. It is sufficiently distinct to constitute a good 
species. 
MUHLENBERGIA WRIGHTI, V.—Culms erect or decum- 
bent, usually branching below, 1 to 2% feet high, somewhat 
compressed, rather wiry; leaves short and somewhat stiff, 3 to 6 
inches long; sheaths smoothish, shorter than the internodes, ligule 
short; panicle spike-like, cylindrical, densely flowered, more or — 
less interrupted; the lower branches are, on thrifty specimens, 
¥% to I inch long, appressed and floriferous to the base; spikelets 
frequently two-flowered; outer glumes nearly equal, about 1 line 
long, with a thin ovate base,and an awned point as long or longer, 
or sometimes lanceolate with a shorter point; flowering glume a— 
little longer and thicker than the outer ones, tipped with a short, © 
stiff awn, % to % line long, three-nerved below, slightly paged 
scent; the palet about as long as its glume.
