Morphology and biology.

Deciduous dwarf shrub with decumbent shoots more than 2 m long and ascendant or erect floriferous stems (50-100 cm). Branches and shoots are covered with numerous short glandular setae and more sparsely with subulate or falcately curved flattened thorns. Leaves are compound, imparipinnate, 4.5-12.5 cm long, consisting of 3-5-7 leaflets. Leaflets are oblong-elliptic or orbed, leathery, with expressly projecting veins from below, glandular-serrate with broad denticles along the edges. Stipules are narrow, glandular along the edges, accreted with the petiole. Pedicels are long, 1.8-5 cm in length, thick, covered with stalk-like glandules. Sepals are broadened at the tip, strongly pinnate, glandular on the back, greatly deflected after flowering. Flowers are single. Corollas are dark- or light-pink, red, 4-6 cm in diameter. Petals are longer than the sepals, sinuate. The fruit is a multi-nut inside an effuse hypanthium, which becomes fleshy and forms the cover of a pseudocarp. Fruits are approximately 1.5 cm long, globular or ovoid, brown-red. This species is entomophilous. It can be ornito- and zoochore. It is propagated by seed and cuttings. Blossoms in June-July; fruits ripen in August-September. Chromosome number: 2n=14.

Speices is a mesophyte; light-demanding and facultative calcephyte. It grows on forest edges and glades, steppe rubble slopes and limestone outcrops, more frequently among bushes. It is a typical plant of oak wood edges. Quite often develops rather extensive thickets.
