Morphology and biology.

Deciduous shrub, 1.5 (2.5) m tall, with thick (up to 3-4 cm in diameter at the base) branches densely covered with numerous variegated thorns, from straight, strongly broadened at the base to thin and needle-shaped. Young shoots are densely pubescent and covered with numerous thorns. Leaves are alternate, compound, imparipinnate, 5-15 (20) cm in length, consisting of 5-9 leaflets. Leaflets are 2-5 cm long, elliptic or ovate, compact, shortly dentate; the upper surface is rugose, glossy, naked, while the underside is densely pubescent (especially along the veins), usually with abundant short-stemmed glandules. Petioles and awns of the leaves have extremely strong pubescence. Pedicels are 1-2.5 cm long, varying from naked to glandular pubescent. Sepals are entire, on the outside often pubescent and glandular. Flowers are single or grouped in 2-6 (7). Corollas are dark-pink, less frequently white, 4-10 (13) cm in diameter. The fruit is a multi-nut inside an effuse hypanthium, which becomes fleshy and forms the cover of a pseudocarp. Fruits are globular, 20-30 mm in diameter, red, pulpy, naked, or occasionally prickly. This species is entomophilous. It is ornito-, zoo- and hydrochore. It is propagated by seed, layers and summer cuttings. Blossoms from the end of June until the first frosts; fruits ripen in late August-first half of September. Chromosome number: 2n=14.
