Description
Salix anticecrenata forms pillow-shaped shrubs a few centimeters high. The leaves have a stalk about 1 millimeter long. The leaf blade is about 1.5 centimeters long, 0.7 centimeters wide, elliptical or obovate-elliptical, pointed, with a wedge-shaped leaf base and a remotely notched leaf margin. Both sides of the leaf are almost bare, the upper side is green and somewhat wrinkled, the underside greenish. Four pairs of nerves are formed.[1]
Growing, elliptical-headed catkins from five to six flowers are formed as inflorescences at the branch ends. The bracts are usually rounded and almost as long as the stamens, more or less membranous, glabrous, sparsely ciliate and three-veined. Male flowers have an adaxial and an abaxial nectar gland. The two stamens are 2 to 2.5 millimeters long, ingrown and bare. The anthers are yellow and elliptical. Female flowers have an adaxially located nectar gland. The ovary is 1.3 to 1.5 millimeters long, narrow ovate, bald and short stalks. The stylus is short and two columns, the scarbilobed. The flowers appear with or after the leaves shoot.[1]
Range
The natural range is on mountain slopes at 3300 to 4200 meters altitude in Nepal, in the northwest of the Chinese province of Yunnan, in the west of Sichuan and in Tibet.[1]
