Stachyurus
Stachyurus is the only genus in the flowering plant family Stachyuraceae, native to the Himalayas and eastern Asia. They are deciduous shrubs or small trees with pendent racemes of 4-petalled flowers which appear on the bare branches before the leaves. The plants have leaves with serrate margins. Pendunculagin, casuarictin, strictinin, casuarinin and casuariin are ellagitannins found in species in this genus. "Stachyurus praecox" from Japan, and the slightly later-flowering "S. chinensis" from China, are both cultivated as ornamental plants, valued for their exceptionally early flowering periods.
