and subcapitate cluster of flowers: leaves all lanceolate, 
acutish, cinereous or subsericeous with a short appressed pu- 
bescence, the upper portion of the stem hirsute: corollas very 
large, the tube much exserted: nutlets sharply ovate-trigo- 
nous, smooth and polished. | | 
At Cushenberry Springs, on the north side of the San Ber- 
nardino Mountains, southern California, S. B. Parish: speci- 
mens distributed for O. leucgphza, from which the species is 
abundantly distinct not only by its short almost capitate in- 
florescence, but much more by the entirely different achenes ; 
these in O. leucophza forming collectively a conical fruit, 
while in the present species the nutlet is as broad as high, 
and the four of them combine to form a depressed-globose or 
almost hemispherical fruit. It is indeed quite such a fruit 
as that of the succeeding group of species, and very far from 
that of O. leucophea and its near relatives. 
O. suFFRUTICOSA (Torr.), Greene, Pitt. i. 57. Low, much- 
branched perennial, with rigid and brittle stems decumbent 
at base or to the middle; leaves small, linear-lanceolate: 
terminal and subterminal geminate spikes with fruiting 
calyces very distinctly biserial: calyx-lobes ovate-lanceolate: 
nutlets rather’ narrowly ovate-trigonous, not strongly de- 
pressed or incurved, the polished surface red-brown dotted 
with many white spots, these slightly elevated and suggestive 
of tuberculation. 
Species peculiar to the elevated plains of the Platte—in- 
cluding the whole region of high country intervening between 
the various branches of that river—throughout southeastern 
Wyoming, and to middle Colorado east of the mountains. 
On passing from middle to southern Colorado, one meets 1n 
the valley of the Arkansas with the following: 
OREOCARYA CINEREA. Perennial, tufted, but the slender 
and flexible stems erect, simple, 8 or 10 inches high, leafy 
throughout, floriferous only near the summit: leaves elon- 
gated, linear-lanceolate, obtuse, cinereous on both sides with
