''Mahonia nevinii'' (syn. ''Berberis nevinii''), known by the common name Nevin's barberry, is a species of flowering shrub in the barberry family. This plant is endemic to southern California, where it is known from very few occurrences in the chaparral of inland canyons and foothills. It is a federally and state listed endangered species. There are thought to be about 500 individuals remaining, with half of those being naturally occurring plants.〔(Center for Plant Conservation Profile )〕 It is also widely cultivated in gardens and parks. ==Description== ''Mahonia nevinii'' is an erect shrub approaching a maximum height of . It has a dense foliage of dark green to bluish-green spiny-toothed, spear-shaped leaflets. It flowers in racemes of 3 to 5 bright yellow cup-shaped, layered blossoms. The fruit is a spherical reddish berry appearing in bunches, in the summer. Some botanists treat ''Mahonia'' as part of the genus ''Berberis''.〔(Flora of North America vol 3. )〕〔Loconte, H., & J. R.
