Leaves: Opposite, stalked, elliptic in outline, most shallowly 3-lobed but some unlobed, jaggedly toothed, often with an isolated pair of glandular teeth near the junction of the blade and stalk, glabrous or hairy beneath, especially along the veins, turning crimson in the fall.
Flowers: Inflorescence a small, compact, flat or rounded cluster of few to several flowers, 1-3 cm across, borne on short axillary stalks with a pair of leaves; flowers all alike and fertile; petals whitish, fused at bases into tubes that flare (4-7 mm wide) at the tops to 5 lobes; stamens inconspicuous, the filaments 1 mm long or less.
Fruits: Berrylike drupes, clustered, red or orange, 0.8-1.5 cm long, each with a single, large, flattened stone.
Shade-tolerant/intolerant, submontane to subalpine, transcontinental North American deciduous shrub.
