description
Salix chaenomeloides is a small tree with dark brown or reddish brown, shiny branches. The leaves have a 5 to 12 millimeter long, initially downy and later balding stalk covered with glands. Leaves with stipules have semicircular or kidney-shaped, glandular serrate and early dropping leaf blades. Otherwise the leaf blade is elliptical, egg-shaped or elliptical-lanceolate, 4 to 8 centimeters long and 1.8 to 3.5, rarely 4 centimeters wide, pointed with a wedge-shaped, rarely rounded or heart-shaped base and a glandular serrate or serrated leaf margin. Both sides are bare, the top is green, the bottom is pale or gray-green.
The male inflorescences are 4 to 5 centimeters long catkins . The inflorescence stalk and the inflorescence axis are hairy down. The bracts are egg-shaped and about 1 millimeter long. Male flowers often have five stamens , the stamens are about 2 millimeters long and finely hairy at the base, the anthers are yellow and rounded. The female kittens are 4 to 5.5 inches long with a diameter of about 1 centimeter. The peduncle is about 2 inches long, the inflorescence axis is hairy tomentose. The bracts are elliptical-obovate. Female flowers have two nectar glands, a large adaxial and a small abaxial. The ovary is stalked long, narrow, egg-shaped and bald. The scar is upside down or outlined. As fruits ovoid-elliptical, 3 to 7 millimeters long are capsules formed. Salix chaenomeloides flowers in April, the fruits ripen in May.
Occurrence
The natural range is in Japan, on the Korean Peninsula and in the Chinese provinces of Hebei , Jiangsu , Liaoning , Shaanxi and Sichuan . It grows in China at altitudes below 1100 meters.
Systematics
Salix Chaenomeloides is a kind from the kind of willow ( Salix ), in the family of the pasture plants (Salicaceae). There she is assigned to the Wilsonia section . It was first scientifically described by Arika Kimura in 1938 . The generic name Salix comes from Latin and was already used by the Romans for various types of willow.
A distinction is made between two varieties: Salix chaenomeloides var. Chaenomeloides : the glands of the petiole are not leaf-shaped, the leaf edge is serrated, the base wedge-shaped. Salix chaenomeloides var. Glandulifolia (C.Wang & CYYu) CFFang : The glands of the petiole are leaf-shaped, the leaf edge is toothed, the base rounded or rarely heart-shaped.
