Ribes bracteosum, Douglas. Californian Black Currant. Shrub, to 8 ft., with upright or ascending sts.: young growth sparingly pubescent and resinous-dotted: lvs. thin, cordate, deeply 5-7-lobed, with ovate to ovate-lanceolate, acute, sharply serrate lobes, 2-8 in. broad: racemes narrow, slender, upright, often 8 in. long; bracts spatulate, half as long as the pedicels, the lower foliaceous; fls. greenish or purplish; calyx-tube cup-shaped; sepals spreading, ovate-oblong, 1/6in. long; petals minute, obtuse: fr. globose, black with whitish bloom, resinous-dotted, edible. Alaska to N. Calif. B.M. 7419.—Hardy at the Arnold Arboretum; remarkable for its large maple-like lvs. and the long bracted racemes. A hybrid of this species with R. nigrum is R. fuscescens, Jancz. (R. bracteosum var. fuscescens, Jancz.); it differs chiefly in its reddish brown fls., in the small linear bracts of the spreading or arching infl., and in the larger fr. Gt. 55, p. 162. Originated in Scotland.
