description
Zabel's cotoneaster is a deciduous shrub up to 2 meters high with spread out to slightly overhanging branches. The twigs have a reddish-brown bark , they are stalk-round, initially dense yellowish hairs and later balding. The leaves are divided into a petiole and a leaf blade. The petiole is 2 to 4 millimeters long and tomentose. The stipules are lanceolate, 2 to 4 millimeters long, with downy hairs and mostly balding until the fruit is ripe. The leaf blade is simple, oval to ovate, 1.5 to 3 centimeters long and 1 to 2 centimeters wide, with a blunt or rarely marginalized tip and a rounded or broadly wedge-shaped base. The upper side of the leaf is dull green and loosely hairy; the underside is densely haired with yellow or gray tomentose hair.
The inflorescences are 1.5 to 3 centimeters wide, pendulous panicles of 3 to 10 or more flowers with tomentose-haired inflorescence spindles. The bracts are 2 to 4 millimeters long and hairy tomentose. The flower stalks are also hairy tomentose and 1 to 3 millimeters long. The flowers are 6 to 7 millimeters in diameter. The flower cup is bell-shaped and has felt hair on the outside. The sepals are triangular, 1 to 2 millimeters long and 1.5 to 2.5 millimeters wide with a blunt or short pointed end. The petals stand upright, they are pink, obovate or rounded, 2 to 3 millimeters in diameter, with a blunt tip. The 18 to 20 stamens are shorter than the petals. The tip of the ovary is finely haired. The two free-standing styles are slightly shorter or the same length as the stamens. The bright red, obovate to ovoid-round fruits have a diameter of 7 to 8 millimeters. Usually two pips are formed per fruit.
Zabel's cotoneaster flowers from May to June, the fruits ripen from August to September.
