OREOCARYA TENUIS Eastwood.—Collected in flower in Long 
Park, near Naturita, on May 22, 1914; alt. about 6500 ft.; no. 337. 
Oreocarya gypsophila, n. sp.—Densely cespitose perennial: 
caudex much branched, woody, and clothed with the petioles of 
former leaves: radical leaves crowded, narrowly spatulate, usually 
folded, 2-3 cm. long, obtuse, canescent with short, stiff, appressed 
hairs which on the dorsal surface are often pustulate at base; blade 
3-4 mm. broad; petioles ciliate with coarse white bristles; stem 
leaves reduced upward, uppermost broadly linear, passing into 
inconspicuous, lanceolate bracts: stems slender, 6-10 cm. high, 
moderately hirsute: inflorescence short-hirsute, not becoming 
fulvous, thrysoid, the relatively few flowers somewhat capitate; 
pedicels short (1-2 mm. long): calyx consisting of five narrowly 
lanceolate, bristly divisions, 6 mm. long; corolla white, salverform, 
tube twice as long as the calyx lobes, limb 12 mm. in diameter, con- 
sisting of five subelliptical lobes, the divisions of which do not reach 
to the throat; crests present but not conspicuous; anthers less than _ 
2mm. long, filaments very short, attached about midway on the 
corolla tube: nutlets broadly ovoid, white, sharply rugose trans- 
versely, all of the nutlets developing. 
This species is probably most closely related to O. cristata Eastwood. Col-

glaucous perennial: stems usually one, 3-6dm. high, erect and 
branched, often becoming blue or purple in the inflorescence: basal 
leaves spatulate, 4-7 cm. long; cauline leaves oblong-spatulate, 
sessile, passing gradually into the much reduced lanceolate
