Leaves of ribes quercetorum
, a small, spreading shrub, are rounded in outline, divided about half way to the attachment point into three lobes, shallowly toothed along the margin, and often with a pair of smaller lobes at the base. Leaf surfaces have a covering of very short, glandular hairs, as do the woody stems. The stems are armed with spines at the leaf nodes; usually one, less often two or three.
Flowers also grow from the nodes, usually paired, sometimes a group of three; all share a single stalk, and they are subtended by a few ovate green bracts. Flowers consist of a hairy, greenish-yellow tube (the hypanthium), opening to five darker yellow sepals, reflexed when mature, 0.1 inches in length. Inside are five shorter, obovate white to pale yellow petals, slightly exserted, and five stamens, a little longer than the petals. Anthers are white. Fruits are spherical berries, initially green, ageing to black.
