The plant Rubus sachalinensis, also known as white-backed bramble, is a shrub or small shrub growing 0.6–2 meters tall. Branches are purplish-brown; young twigs are lighter in color, softly hairy, and become glabrous with age. The plant is densely covered with yellow, brown, or purplish-red erect prickles mixed with glandular hairs. Leaves usually have three leaflets (sometimes five on sterile shoots), which are ovate, ovate-lanceolate, or elliptic-ovate, 3–7 cm long and 1.5–4(5) cm wide. The apex is acute, often gradually tapering on terminal leaflets, and the base is rounded—sometimes shallowly cordate on terminal leaflets. The upper surface is glabrous or slightly hairy, while the lower surface is densely covered with gray-white tomentum. Margins are irregularly coarsely serrated or incised. Petioles are 2–5 cm long; terminal leaflet stalks are 1–2 cm long, lateral leaflets nearly sessile; all bear soft hairs, prickles, or glandular hairs. Stipules are linear, hairy or sparsely glandular. Flowers, numbering 5–9, form cymose inflorescences that are terminal or axillary, rarely solitary in leaf axils. Peduncles and pedicels are hairy and densely covered with prickles and glandular hairs. Pedicels are 1–2 cm long; bracts are small and linear, bearing soft hairs and glandular hairs. Flowers are about 1 cm in diameter. The calyx exterior is densely short-pubescent, with prickles and glandular hairs. Sepals are triangular-lanceolate, about 1 cm long, with elongated acuminate tips, often erect and spreading during flowering and fruiting, with gray-white tomentum along margins. Petals are tongue-shaped or spoon-shaped, white, shorter than sepals, with clawed bases. Stamens are nearly equal in length to the style. The base of the style and ovary are pubescent. Fruit is ovoid, relatively dry, about 1 cm in diameter, red, and hairy; seeds are wrinkled. Flowering occurs from June to July; fruiting from August to September.
