242 Eastwoop: New SprcigES OF OREOCARYA 
long, the surface under the bristles clothed with fine white densely 
and intricately appressed hairs : radical leaves spatulate to oblanceo- 
late, together with the margined petioles 3 cm. long, 8 mm. wide, the 
midrib forming a ridge on the lower surface ; cauline leaves ob- 
lanceolate, about as long as the radical leaves but narrower : spikes 
peduncled, longer than the subtending leaves, distichous or uni- 
lateral ; bractlets linear, longer than the internodes, shorter than the 
mature calyx ; pedicels very short, about 0.5 mm. long : divisions of 
the calyx subulate-acuminate, equalling the tube of the corolla in 
flower, elongating from 3-10 mm., strongly ribbed, densely setose, 
not conniving over the nutlets but spreading open and becoming 
campanulate, readily disarticulating from the peduncles when the 
seed is ripe, leaving an umbilicate scar at the base of each spread- 
ing bractlet : corolla white ; tube equal tothe limb, together 6 mm. 
long; divisions not extending to the throat, obovate with the apex 
obcordate or obtuse, 2.5 mm. broad, margin obscurely sinuate ; 
crests conspicuous, I-nerved, truncate, 0.5 mm. long and as broad; 
crests at base less than I mm. from the bottom, forming a monili- 
form ring of 10 nipple-like projections around and above the ovary: 
anthers oblong, 1.25 mm. long, concealing the short broad fila- 
ments and extending to the base of the crests: nutlets erect, 2.5 
mm. long, ovate, obtuse, the dorsal ridge prominent, acutely mar- 
gined all around; scar sulcate, extending almost to the apex, not 
forked at base, rough with glossy white papillae which are con- 
fluent into small papillae, becoming somewhat star-shaped in out- 
line, the smaller papillae intervening: gynobase linear-subulate. 
This is near O. thyrsiflora Greene, but is entirely distinct. It 
was collected by the author at Grand Junction, Colorado, June 27, 
1892. 
Oreocarya Wetherillii 
Biennial from a slender tap-root, the caudex densely clothed 
with the petioles of former leaves, branched from the base with 
one stout stem and one or more low slender ones, 1-3 dm. high: 
leaves and stem white with densely appressed interlaced fine hairs 
and spreading bristles pustulate at base: radical leaves spatulate, 
obtuse or acute, with blades as long as the broad margined peti- 
oles, which are dilated and imbricated at base, 1-3 cm. long, 5-10 
mm. broad: glomerule extending from the base, consisting of 
numerous unilateral or distichous spikes with oblong sessile bracts 
diminishing upwards; bractlets linear-lanceolate, equalling or 
surpassing the calyx: calyx of 5 narrow, linear divisions, 5 mm. 
long, densely hispid with white bristles, which are tawny in bud, 
in fruit conniving over the nutlets but with spreading tips, becom-
