Shrubs 1–2 m tall. Branchlets brown or reddish brown, terete, sparsely tomentose when young, with sparse prickles, without stalked glands. Leaves imparipinnate, 5–7-foliolate, rarely 3-foliolate; petiole 3–6 cm, petiolule of terminal leaflet ca. 1 cm, petiolule and rachis tomentose, with sparse, minute prickles, without glandular hairs; stipules linear, pubescent; blade of leaflets narrowly ovate or elliptic, often ovate on terminal leaflet, 3–8 × 1.5–4.5 cm, abaxially densely tomentose, adaxially glabrous or pilose, base rounded, sometimes subcordate on terminal leaflet, margin unevenly coarsely serrate or doubly serrate, sometimes lobed on terminal leaflet, apex shortly acuminate. Inflorescences terminal, short racemes, rarely several flowers in clusters in leaf axils; rachis, pedicels, and abaxial surface of calyx densely tomentose, with dense or sparse, needle-like prickles, without glandular hairs; bracts linear, soft hairy. Pedicel 1–2 cm. Flowers 1–1.5 cm in diam. Sepals erect, ovate-lanceolate, margin gray tomentose, apex caudate. Petals white, spatulate, puberulous or glabrous, base broadly clawed. Stamens many, shorter than petals; filaments broadened and flattened. Pistils shorter than stamens; ovary and base of style densely gray tomentose. Aggregate fruit red or orange, subglobose, 1–1.4 cm in diam. densely shortly tomentose; pyrenes prominently pitted. 2n = 14*.
Shrubs, 5–25 dm, armed or unarmed. Stems ?biennial?, erect, glabrescent, eglandular or stipitate-glandular, strongly pruinose; prickles absent or sparse to dense, erect, weak, 1–4 mm, broad-based; ?bristles present or absent?. Leaves deciduous, pinnately compound; stipules filiform, 5–10 mm; ?petiole unarmed or with prickles, strigose or glabrous, glandular or eglandular; terminal leaflets petiolulate, lateral sessile or subsessile?; leaflets 3–5(–7), terminal ovate to lanceolate, 7–15 × 4–11 cm, base rounded to cordate, unlobed or 2-lobed, margins serrate to doubly serrate, apex acute to attenuate, abaxial surfaces unarmed or with prickles, strongly white-tomentose, eglandular or glandular. Inflorescences terminal and axillary, (1–)3–7(–20)-flowered, racemiform. Pedicels unarmed or prickles sparse, hooked, glabrous or sparsely pubescent, stipitate-glandular or eglandular. Flowers bisexual; petals white to greenish white, spatulate to obovate, 5–10 mm; filaments filiform or slightly dilated basally; ovaries pubescent. Fruits usually red to whitish, rarely amber, globose to conic, 0.5–2 cm; drupelets 10–60, coherent, separating from torus.
"Stems to 2 m, erect, spreading, or decumbent, sparsely to densely armed with slender-based prickles and stiff, glandular bristles; primocane lfls 3 or 5, ovate to lanceolate, acuminate, sharply serrate mostly above the middle, softly gray-pubescent beneath; intermediate pair of lfls, when present, inserted close to the terminal lfl; infl an umbelliform cyme of 2–5 fls, often also with 1 or 2 solitary fls from the upper axils; pedicels stipitate-glandular and ± bristly, the bristles exceeding the glandular hairs and gland-tipped when young; sep soon reflexed; pet white or greenish-white, spatulate to obovate, erect, shorter than the sep; fr red (yellow), 1–1.5 cm thick, separating as a unit from the persistent receptacle; 2n=14, seldom more. Dry or moist woods, fields, and roadsides; Nf. to Alas., s. to Pa., Ind., Io., and Ariz. May–July. The Amer. and e. Asian plants, as here described, constitute the var. strigosus (Michx.) Maxim., in contrast to the eglandular Eurasian var. idaeus, which is cult. in many cultivars. At the subspecific level our plants would be subsp. melanolasius Focke. (R. strigosus)"
