Santa Rita Mts., Arizona, alt. 4,500-6,000 feet. April. 
Both the male and female plants are represented, 
75? 76. Poa — probably forms of P. tentiifolia, Nutt. The first, 
from the mountains about the head-waters of the Sacramento River, 
has a stout culm with flat radical and cauline leaves, 2-4 in. long, 
the outer glumes obtuse, the upper one over 2 lines long, equalling 
the first floret ; the second, from Mt. Shasta, more nearly approaches 
the typical form of the species. 
n. ^^Poa anmia, L., var. stricta^ Vasey. Panicle narrow, 3-5 in. 
long with erect branches. Truly indigenous. 
Banks of the Rillita. 
78. Poa Pringlii, n. sp. — Culms about 6 in. high, slender and 
scape-like, with a single leaf below the middle, densely tufted from a 
creeping root-stock, the base surrounded by the loose sheaths of the 
radical tuft of short (1-2 inches) convolutely folded, smooth and nar- 
row leaves. The cauline leaf about \ an inch long, narrow and 
folded like those at the base, minutely scabrous at the somewhat 
pungent tip. Panicle about an inch in length, narrow and few- 
flowered ; lower branches in pairs, bearing one or two spikelets 
which they about equal in length. Spikelets 3-4 lin.long, 3-5-flow- 
ered. Outer glumes broadly lanceolate, three-nerved below, with 
broad scarious margins, the upper one about as long as the spikelet, 
the lower a Itttle shorter and smaller. Flowering glume about 3^ 
lines long, broadly lanceolate, with a broad scarious margin above, 
5-nerved, minutely punctulate-scabrous all over and strongly scabrous 
on the midnerve above, smooth below. Pale one-fourth shorter 
than its glume. Scales broad and irregularly cut or toothed. 
^ Mountains about the head-waters of the Sac^ramento River, Cal- 
ifornia. September. 
There is considerable variation in the size of the spikelets, 
which, in most specimens, are purplish in color and have a membra- 
peous appearance. It is apparently dioecious. The staminate plant 
IS more slender, with more acute glumes. 
The species is allied to Atropis Calif arnica, Munro, but appears 
to be sufficiently well marked to be kept distinct.
