description

Leaves and fruits

Franchets cotoneaster is an evergreen or wintergreen, 1 to 3 meter high shrub with overhanging, dark gray-brown or black-gray, initially densely hairy and later balding branches. The leaves are divided into a petiole and a leaf blade. The petiole is 2 to 4 millimeters long and tomentose. The stipules are linear-lanceolate, 2 to 4 millimeters long, initially hairy tomentose and later balding. The leaf blade is simple, oval to ovate, 2 to 3 inches long and 1 to 1.5 inches wide, with a pointed or tapered tip and a wedge-shaped base. The upper side of the leaf is matt, shiny and finely wrinkled, initially hairy and later balding with deeply sunken leaf veins ; the underside is densely hairy yellow to silvery tomentose with protruding leaf veins.

The flowers grow in 1.5 to 2.5 centimeters measured by Schirmrispen from 5 to 11 flowers with felted dense hairy inflorescence stem. The bracts are linear, 2 to 3.5 millimeters long and tomentose. The flower stalks are also hairy tomentose and 2 to 4 millimeters long. The flowers are 6 to 7 millimeters in diameter. The flower cup is bell-shaped and has dense downy hair on the outside. The sepals are triangular, pointed or pointed, 1 to 2 millimeters long and 1.5 to 2.5 millimeters wide. The petals are erect, pink, broadly obovate or oval, 3 to 4 millimeters long and 2 to 3 millimeters wide, with a blunt tip and a short nailed base. The top is finely haired at the base. The 20 stamens are shorter than the petals. The tip of the ovary is hairy downy. The two or three sometimes up to five free-standing styles are shorter than the stamens. The fruits are 6 to 7 millimeters in diameter. They are orange-red or red, ovate-round, initially hairy and later balding. Usually three, rarely up to five seeds are formed per fruit. Franchet's cotoneaster flowers in June and July, the fruits ripen from September to October.
