|discussion=<p><i>Sorbus californica</i> is recognized here in the narrow sense, occurring north to Crater Lake National Park, Oregon (P. F. Zika 2003). The concept in H. A. McAllister (2005) differs, including plants of British Columbia and Washington treated here as <i>S. scopulina</i>. <i>Sorbus californica</i> is distinct in its shiny leaflets less than 4 cm with rufous hairs in the axils. Where their ranges overlap, <i>S. scopulina</i> has hairier inflorescences, leaflets usually more than 4.5 cm, and whitish axillary hairs. The small leaflets and essentially glabrous inflorescences help distinguish <i>S. californica</i> from putative hybrids between <i>S. scopulina</i> and <i>S. sitchensis</i> found farther north, which are otherwise similar with their somewhat shiny leaflets, slightly glaucous fruits, and red axillary hairs. Some collections of <i>S. californica</i> from California are intermediate with either <i>S. sitchensis</i> or <i>S. scopulina</i> and may represent hybrids with those two species.</p>
