description

The willow-leaved cotoneaster is a mostly evergreen shrub up to 5 meters high with spread out to upright branches. The twigs are reddish-brown to gray-brown, initially densely tomentose and later balding. The leaves are divided into a petiole and a leaf blade. The petiole is often red in color, thick, 4 to 5 millimeters long and tomentose. The stipules are brown, linear or linear-lanceolate, 4 to 7 millimeters long, slightly tomentose hairy and sloping early. The leaf blade is simple, oval-elongated, ovate-lanceolate or linear-lanceolate, 4 to 8.5 inches long and 1.5 to 2.5 inches wide, with entire margins, pointed or pointed and with a wedge-shaped base. 12 to 16 veins are formed. The upper side of the leaf is bald or finely haired, wrinkled with sunken leaf veins; the underside is hairy gray tomentose with protruding leaf veins.

The inflorescences are 3.5 to 6 centimeters long and 3 to 4 centimeters in diameter, composite panicles of many flowers with tomentose-haired inflorescence spindles. The bracts are linear, 3 to 5 millimeters long and soon fall off. The flower stalks are tomentose and 2 to 4 millimeters long. The flowers are 5 to 6 millimeters in diameter. The flower cup is bell-shaped and has gray-tomentose hair on the outside. The sepals are triangular, 1.5 to 2.5 millimeters long and pointed or pointed. The petals are horizontal, they are white, egg-shaped or rounded, 2.5 to 4 millimeters long and 3 to 4 millimeters wide, glabrous, with a blunt tip and a short nailed base. The approximately 20 stamens are slightly longer or about the same length as the petals. The anthers are reddish. The tip of the ovary is finely haired. The two to three free-standing styles are the same length or slightly shorter than the stamens. The scarlet, obovate, round or egg-shaped fruits are 3 to 7 millimeters in diameter. Two or three pips are formed per fruit. The willow-leaved cotoneaster flowers in June, the fruits ripen in October.

The number of chromosomes is 2n = 34.

Occurrence and location requirements

The natural range is in the Chinese provinces of Guizhou , Hubei , Hunan , Sichuan and Yunnan . The willow-leaved cotoneaster grows in mountain regions, in mixed forests, slopes and open areas at an altitude of 400 to 3000 meters.

Systematics

The cotoneaster salicifolius ( Cotoneaster salicifolius ) is a kind of the genus of cotoneaster ( Cotoneaster ). It is in the family of the rose family (Rosaceae) of the subfamily spiraeoideae, tribes of the subtribe Pyreae maloideae assigned (Pyrinae). The species was first scientifically described in 1886 by Adrien René Franchet as Cotoneaster salicifolia . The generic name Cotoneaster is derived from the Latin "cotoneum malum" for the quince ( Cydonia oblonga ). The ending "aster" is a coarse form for groups of plants that are considered inferior in comparison to similar groups. The specific epithet salicifolius comes from Latin, salix means "willow" and -folius means "-blättrig", together therefore "willow-leaved".

use

Numerous cultivars are attributed to the species, many of which arose from crossings with closely related species. According to another opinion, the cultivars are only incorrectly assigned to Cotoneaster salicifolius and were bred from a different species.
