...Rosa woodsii subsp. ultramontana occurs from central British Columbia east to Idaho, western Wyoming, and probably also western Montana, south to California, east of the Cascade Mountains, and Utah, Nevada, and infrequently as disjunct populations in Arizona and New Mexico.

Rosa woodsii Lindley, Ros. Monogr. 21. 1820....
Key to the subspecies of Rosa woodsii in Central and Western North America:
- Shrubs most frequently tall, 1-3 (-5) m; flowering branches unarmed or with straight or curved prickles; terminal leaflets ovate to elliptic, fewer obovate; flowers 1 or 2 or corymbose and then 3 to 10 (to 15); western North America including the far Southwest.
-- Prickles straight or occasionally somewhat curved, absent or few to dense; flowers few, 3 most common or numerous (to 15); sepals eglandular or infrequently stipitate-glandular; intermontane between Cascade and Rocky Mtns. of British Columbia to southern Great Basin and mountains of Majave Desert, and east to Rocky Mtns.
---Stems openly branching; prickles absent or sometimes scattered and/or infrastipular paired , predominately straight; flowers commonly corymbose, 3 to 10 (to 15); intermontane between Cascade and Rocky Mtns., common in Great Basin....subsp. ultramontana.

Rosa ultramontana (Wats.) Heller. Mountain Rose. Fig. 198.
An erect shrub, 2 to 6 feet high, armed with slender usually straight prickles, or nearly unarmed. Leaflets 5 or 7, oval, glabrous above, puberulent and sometimes a little glandular beneath. Flowers usually several in a corymbose cluster; pedicels glabrous; sepals lanceolate, not glandular; petals obcordate, ½ to ¾-inch long; hypanthium globose; 3/8-inch to ½-inch long, glabrous. Flowering period, June and July.
Mountain Rose occurs chiefly on the eastern side and to the east of the Sierra Nevada from Modoc county southwardto Inyo and Kern counties, at elevations from 3500 to 10,900 feet (Slate Creek Basin, Mono County, J. Clausen). It also occurs sparingly in the mountains bordering the western Mohave Desert. It extends northward to British Columbia and eastward to Nevada.
