- 244 Eastwoop: New SPEcIES OF OREOCARYA 
papillae intervening ; ventral surface with coarser papillae ; scar 
open and broad like a furrow, forked at base, reaching within 0.5 
mm. of the apex: gynobase elongated-subulate. 
This is perhaps nearest to O. cacspitosa A. Nelson from which 
it differs in fruit and floral organs as well as habit and pubescence. 
It was collected by the author near Grand Junction, Colorado, on 
the mesa above the Gunnison River, May 17, 1892. 
Oreocarya cristata 
Caudex with many branches from a slender woody tap-root, 
apparently perennial ; stems slender, about 2 dm. high, ribbed, not 
floriferous at base, pubescent with appressed tangled hairs and fine 
spreading white bristles which are 2 mm. long: leaves oblanceo- 
late-spatulate, with broad petioles dilated at base, the lower ones 
twice as long as the blades, the upper about equalling them, to- 
gether 1.5-5 cm. long; blades 6 mm. broad; petioles 4 mm. 
broad at base ; pubescence on younger leaves tawny, that on older 
ones cinereous with appressed hairs and bristles, the latter pustu- 
late at base ; pubescence of inflorescence gray or tawny : inflores- 
cence a compound spike or glomerule, little more than half as 
long as the stem ; peduncles 2-4 mm. long ; pedicels about 1 mm. 
long: spikelets 2—4-flowered: calyx of five lanceolate very 
bristly divisions 6 mm. long, not enlarging much in fruit, shorter 
than the tube of the corolla, with pubescence gray or tawny: 
corolla with broad orbicular divisions, not extending to the throat, 
4 mm. broad ; tube almost 1 cm. long; crests in throat conspicu- 
ous, oblong, I mm. long, without scales or crests at base : anthers 
oblong, more than 2 mm. long, almost sessile, the apex I mm. 
from the base of the crests: nutlets globose, incurved, ovate, 
acutely margined to the scar, rough with transverse ridges and 
minute papillae intervening ; scar broad and open, with open, fork- 
ing base: gynobase mitriform. 
This is peculiar in the broad limb of the corolla with orbicu- 
lar lobes, the prominent crests in the throat of the corolla-tube, 
and the peculiar nutlets of which one was generally abortive. 
This was collected by the author at Grand Junction, May 17, 
1892. 
Oreocarya tenuis 
Caudex densely clothed with dry imbricated petioles, much 
branched from a woody tap-root having a dark brown epidermis : 
stems many, slender, erect, 1-2 dm. high, ribbed, floriferous from 
near the base with few scattered flowers or clusters, above becom-
