RYDBERG: Rocky MounTAIN FLORA 561 
sepals lanceolate, acuminate, about 2 cm. long, erect and per- 
sistent in fruit, tomentulose above, glandular and bristly beneath, 
often with linear lobes; petals obcordate, about 2. 5 cm. long and 
fully as wide ; hip in fruit more or less pear-shaped, about 3 cm. 
long and 2 cm. in diameter, sparingly bristly. 
This species has the general habit of R. Nutkana and R. Mac- 
Dougalii, but differs from both in the curved prickles. It has 
bristly fruit as the latter, but the fruit is more tapering at the base 
and the bristles fewer. It grows in the mountains at an altitude 
of 2,300—2,700 m.

~ Rosa oreophila sp. nov. 
__ Ashrub 2-3 m. high ; bark reddish, glossy ; prickles mostly 
infrastipular or lacking, weak, 5 mm. long or less, curved with 
elliptic bases ; stipules broad, finely pubescent and glandular- 
denticulate on the margin ; free portion ovate, 5-15 mm. long ; 
faves 7~10 cm. long, 5—7-foliolate ; rachis and petiole finely 
pubescent and with sessile glands ; leaflets 2~3.5 mm. long, ovate 
or oval, acute or obtuse, glabrous and dark green above, sparingly 
and finely pubescent and paler beneath, coarsely serrate ; flowers 
mostly solitary ; sepals narrowly lanceolate, acuminate, finely pu- 
Scent on both sides and glandular-denticulate on the margins, 
crect and persistent in fruit; petals obcordate, 2—2.5 cm. long ; 
hip glabrous, when ripe fully 2 cm. long, often acute at the base. 
This js perhaps nearest related to the preceding, but differs in 
the smooth and more rounded fruit and more slender prickles. It 
§rows at an altitude of 2,300—2,500 m.
