AppearanceIt is an evergreen shrub with short vertical stems, mostly under 30 cm , while the leaves reach higher, rarely up to 2 m tall. The leaves are compound, with 9-19 leaflets; each leaflet is strongly toothed, reminiscent of holly, and somewhat shiny, but less so than tall Oregon-grape. The leaflets do not have a single central vein as in that species, but several veins arranged fan-like, branched from the leaflet base, hence the epithet ''nervosa''. The flowers and fruit are like those of other Oregon-grapes, and are equally bitter-tasting.
UsesSome Plateau Indian tribes drank an infusion of the root to treat rheumatism.
