description

Salix capusii is a shrub up to 6 meters high with a dull gray bark . The branches are maroon, thin and bare. Young twigs are yellowish and finely hairy. The leaves have linear and deciduous stipules . The petiole is 2 to 4 millimeters long, initially finely haired and later balding. The leaf blade is linear-inverted-lanceolate or narrowly lanceolate, 4 to 5 centimeters long and about 6 millimeters wide, pointed to a short point, with a wedge-shaped base and a whole-or serrated leaf margin. Both leaf sides are uniformly gray-blue, initially tomentose and later balding.

The male inflorescences are 4 to 4.5 centimeters long and 6 to 8 millimeters in diameter, sitting or short-stalked catkins with a leafy base. The bracts are yellowish green, oblong to oblong-obovate, about half as long as the stamens, with an almost clipped tip, down-haired upper side at the base and bald or sparsely shaggy-haired underside. The male flowers have two stamens with overgrown and finely hairy stamens at the base and yellow and round anthers. Female kittens are 1.5 to 2.5 inches long and grow even longer when the fruit is ripe. The stem is leafy. The bracts correspond to the male but are partially obsolete until the fruit is ripe. Female flowers have a narrow, conical, glabrous, 1 millimeter long stalked ovary . The stylus is short, the scar conspicuous. The fruits are greenish or yellowish, conical, 4 to 5 millimeter long capsules . Salix capusii flowers from April to May, the fruits ripen from May to June.
