A deciduous shrub of the Thymelaeaceae family with three branches and golden-yellow flowers (illustration). It is cultivated as a raw material for Japanese paper and as a flowering tree. Its Chinese names are Yuxiang and Huangruixiang. It is 1-2m tall, and in July the tips of new branches suddenly split into three, growing densely. The leaves are alternate, oblong or lanceolate, 8-25cm long, and hairy on the underside. In autumn, inflorescence buds wrapped in leaf-shaped bracts on 1-2cm stalks appear in the upper axils of the branches. The inflorescence is a head containing 30-50 flowers, which open in March and April, earlier than the leaves. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
