Medium shrub, 0.5-2 m tall, perennial with biennial stems (canes); stems erect to ascending, almost unarmed to prickly and bristly, often glandular-hairy, sometimes smooth and glaucous beneath the prickles; bark yellow to cinnamon-brown, shredding; similar to cultivated raspberry.
Alternate, deciduous, pinnately compound, 5-20 cm long; leaflets 3 to 5 on first-year canes, mostly 3 on flowering canes, egg-shaped to broadly lanceolate, 3-10 cm long, double-saw-toothed and sharply long-pointed at the tip, greenish and smooth to sparsely hairy above, paler and greyish-woolly to nearly smooth beneath, the veins and leaf-stalks often glandular-prickly; stipules linear-awl-shaped, 4-10 mm long.
Inflorescence of 1 to 4 stalked flowers in small, open, nodding, axillary or terminal clusters, the stalks often bristly-glandular; corollas white, the petals 5, erect, oblong-spoon-shaped, 4-7 mm long; calyces hairy to glandular-bristly, 5-lobed, the lobes lanceolate, bent back, 4-8 (12) mm long; ovaries superior; stamens 75-100.
Drupelets, finely and thinly woolly, weakly coherent in a red egg-shaped cluster that falls intact from the dry receptacle (a raspberry), the berries 1-1.2 cm wide.
