description
The tea-leaved willow is a shrub that reaches heights of up to 4 meters. The bark of young twigs is initially slightly hairy, but later glabrous and of a shiny yellowish to brown color.
The leaves are divided into a petiole and a leaf blade. The leaf stalks are up to about 12 millimeters long. The simple, entire or slightly sawn leaf blade is 2 to 8 centimeters long and 1.3 to 5 centimeters wide and round, elliptical to ovoid or obovate. The underside of the leaves is green to blue-green, the upper side is glossy green, initially a bit hairy but later glabrous. Stipules are rare and, if present, small.
The strongly branched, short-branched catkins appear shortly before ( anthesis ) in May. They are mostly kittens 2 to 3.5 inches long. The kitten scales are two-colored, dark brown to blackish at the tip and lighter at the base. The flowers have two stamens . The anthers are yellow or somewhat reddish, the stamens glabrous and ingrown.
The number of chromosomes is 2n = 114.
Occurrence
The tea-leaved willow thrives in the Arctic zone as well as in the alpine altitude level analogous to the polar zones in Europe , as well as in the Mediterranean area , the Middle East and Western Siberia .
