Shrubs, 10–25+ dm, usually forming thickets. Stems openly branched; prickles usually present on distal stems and branches, infrastipular strongly curved or hooked, sometimes introrse, stout, sometimes flattened, 2–8 mm, internodal sparse or absent. Terminal leaflets usually elliptic, rarely cordate or narrowly ovate, 10–30 mm. Inflorescences 1 or 2(–4)-flowered. Sepals: abaxial surfaces usually stipitate-glandular, sometimes eglandular. 2n = 14.


Phenology: Flowering May–Jun.
Habitat: Sandy soil of oak, juniper, and pine forests, alluvial flats, brushy hillsides, sandstone cliff bases, sunny road banks

Discussion

Subspecies arizonica occurs primarily along streams in forested areas of Arizona, southern Nevada (Spring Mountains), northwestern New Mexico, and southern Utah with extensions into mountainous regions. Tall open habit, strongly curved prickles, and stipitate-glandular sepals are diagnostic, although not always present in combination. Plants with relatively few or no prickles, endemic to the West Fork of Oak Creek Canyon in Coconino County, Arizona, are var. ertterae W. H. Lewis, the Ertter rose; conservation attention to this variety is warranted. The remainder of the subspecies is var. arizonica.
