Berberis nevinii (syn. Mahonia nevinii, Odostemon nevinii[2]), 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 riparian areas of chaparral in inland canyons and foothills. It is a California state and United States federally listed endangered species, since 1987[3] and 1998,[4][5] respectively. There are thought to be about 500 individuals remaining, with half of those being naturally occurring plants.[6] It is also cultivated in gardens and parks as an ornamental and barrier plant.[7][8]

Description

Berberis nevinii is an erect,

rhizomatous shrub approaching a maximum height of 4 metres (13 ft). 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, that appear in spring between March and April.[9] The fruit is a spherical reddish berry
appearing in bunches, in the summer, eventually darkening to a dark blue.

Taxonomy

Taxonomic history

The plant was first described by American botanist Asa Gray, in 1895, named in of honor fellow botanist, Reverend Joseph Cook Nevin (1835-1912), who was active in China and Southern California, particularly in the Channel Islands.[1][10] It was later described in 1901 by Fedde and Engel as Mahonia nevinii.[1][11] Gray's original description for the plant was the following:

Berbericidae, Berberis. B. Nevinii, Gray, n. sp. Leaflets 3 to 7,

Berberis fascicularis
being limited to the Mexican species, which seems distinguishable from the Californian B. pinnata by its more numerous, more acuminate, and less shining leaflets.

Though debate between botanists on the correct classification continues in the 21st Century, as of 2023 the most common place ment of the species is again in Berberis as Berberis nevinii.[1][22][13]

Distribution and habitat

Populations were historically found in washes of the

bladderpod.[24]

There are currently about 21 known populations of the plant remaining, and almost all of them have fewer than 20 individuals, with some with as few as 5 individual plants.

Devil's Gate Dam, Arroyo Seco, the Rose Bowl, Rimforest, and San Timoteo appear to be introduced, according to a 2009 Southern California Edison Environmental Report for a renewable transmission line project in the Tehachapi Mountains.[9] The same report states that plants in the San Francisquito canyon appear to be the only naturally regenerating population, despite having been introduced by seed.[9]

Threats to the species include habitat loss due to destruction, fragmentation of existing populations due to road-widening, degradation from urban development, off-road vehicle use, horseback riding, modified fire regimes, gold extraction activities, biocides,[9] and displacement by exotic plant species, such as Spanish broom.[25][27][9] Additionally, it appears that the plant does not seed easily or frequently, which means that the community does not regenerate as quickly as competing species; the single individual at Dripping Springs successfully reproduced 56 years after it was initially documented.

Cultivation

Berberis nevinii is cultivated as a

native plant and wildlife gardens, natural landscaping of parks in its range, drought tolerant landscaping, and for habitat restoration projects.[23]

It can serve as an impenetrable barrier hedge, due to the spiny-toothed dense foliage. With berries appearing in the summer, earlier/later than other chaparral plants, it is an attractive bird food plant.[23] The plant was introduced into cultivation in California by Theodore Payne in the 1920s.[23][26]
