|discussion=<p>Variety grayi often has smaller leaflets than <i></i></i>var.<i><i> sitchensis</i>, and plants near timberline frequently are dwarfed by exposure. It is usually found at higher elevations or on boggier soils than <i></i></i>var.<i><i> sitchensis</i>. The rank is controversial; it was treated by G. N. Jones (1939) and H. A. McAllister (2005) as a species (<i>Sorbus</i> occidentalis). The only reliable character to segregate it is the extent of toothing on the leaf margins, which is variable on some individuals, with nearly entire leaflets on shoots exposed to sun and with leaflet margins to 50% toothed on shaded basal shoots.</p><!--
--><p>Variety grayi occurs south to Crater Lake National Park in Klamath County, Oregon (P. F. Zika 2003). Most collections and reports from California (T. J. Rosatti 1993) were misidentified, except for a single sheet from Siskiyou County in the Klamath Mountains (R. White 207, HSC). One of the synonyms, <i>Pyrus</i> occidentalis, was described with several syntypes from California, which are not <i></i></i>var.<i><i> grayi</i> but <i>Sorbus californica</i>. G. N. Jones (1939, p. 40) effectively lectotypified <i>P. occidentalis</i> with a syntype from the Canadian border (Lyall s.n., GH), which has nearly entire leaflets and is <i></i></i>var.<i><i> grayi</i>.</p>
