Salix chaenomeloides
Salix chaenomeloides is a species of willow native to Japan, Korea, and China. The species was first described in 1938 by Arika Kimura.
They are deciduous trees, reaching heights of 10–20 m. Trees are either male or female, and prefer moist or wet soils, generally growing in or near water.
The Seongju Gyeongsan-ri Seongbaek Forest is a Korean Natural Monument which protects a stand of these trees, in Seongju.
