Sorbus californica
species of plant

Sorbus californica, the California mountain ash, is an aggregate species of rowans. It forms a tree or bush with compound leaves (many leaflets) that are toothed almost from base to apex. It produces orange-red fruit. It is often confused with the western North American species S. sitchensis, which has leaflets with few teeth and pinkish fruit.
The species is native to western North America. It is found in the mountains of California as the name suggests, but is not an ash. It is sometimes cultivated.
This brief starts where responsible research should: with the source description of “Sorbus californica” as species of plant. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of plant. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Feb 1, 2025. The linked authority identifier is Q3926584. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
