description

The Peking cotoneaster is a deciduous, 2 to 4 meter high, broad- growing shrub with thin, protruding, brown, initially hairy and later bare branches. The leaves are divided into a petiole and a leaf blade. The stem is 2 to 5 millimeters, rarely up to 10 millimeters long and shaggy hairy. The stipules fall off early; they are 3 to 5 millimeters long, linear-lanceolate, brown and slightly shaggy hairy. The leaf blade is simple, oval-ovate to oblong-ovate, 2 to 4 seldom to 5 centimeters long and 1 to 2 seldom 3 centimeters wide, pointed or seldom pointed, with a broad wedge-shaped base. The upper side of the leaf is bare or, like the underside, initially shaggy and hairy and slowly balding; the leaf veins protrude from the underside of the leaf.

The inflorescences are 2 to 4 centimeters in diameter panicles of 2 to 5 flowers . The spindle and flower stalks are hairy shaggy. The bracts are linear-lanceolate, 3 to 5 millimeters long and slightly hairy. The flower stalk is 3 to 5 millimeters long, the individual flowers are 7 to 8 millimeters in diameter. The flower cup is bell-shaped or short cylindrical and bare or shaggy on the outside. The sepals are triangular, 1 to 2 millimeters long and 1.5 to 2 millimeters wide and pointed or more or less blunt. The petals stand upright. They are white with a reddish tint, broadly obovate or oblong, 3.5 to 4.5 millimeters long and 3 to 4 millimeters wide, with a blunt tip and a slightly longer nail . The ten to 15 stamens are shorter than the petals. The ovary is hairy densely shaggy at the top. The detached, often twice the stylus does not protrude beyond the stamens. The fruits are 6 to 8 millimeters in diameter. They are black, oval, obovate or rounded and hairy with shaggy hair. Two to three pips are formed per fruit. The Peking cotoneaster flowers from May to June, the fruits ripen from August to September.
