Berberis dictyota is a plant species endemic to California but very widespread in that state, found from San Diego County to Siskiyou County. It is generally found in open shrubby locations at elevations of 600–1800 m.
Berberis dictyota is an evergreen shrub up to 2 m tall. Leaves are pinnate, with 5-7 leaflets; leaflets thick and rigid, whitish with a thick waxy layer on the underside, up to 9 cm long, with spines along the edges. Flowers are borne in dense racemes of up to 50 flowers. Berries are egg-shaped, dark blue, sometimes with a waxy coating, up to 7 mm long.
