A deciduous shrub, 6 to 12 ft high, allied to S. pubens and S. racemosa, having its flowers and fruits in panicles as in those species, but the panicles are usually broader in proportion to their height. The berries, moreover, are not red but black, and without bloom. Leaflets five or seven (sometimes nine), their chief veins and midrib more or less downy beneath when young, but not so downy as S pubens. Native of western N. America; introduced to Kew in 1894.
