Pterostyrax

Pterostyrax, the epaulette tree, is a small genus of four species of deciduous large shrubs or small trees in the family Styracaceae, native to eastern Asia in China and Japan. They grow 4 - 12 m tall, with alternate, simple ovate leaves 6 - 17 cm long and 4 - 10 cm broad. The flowers are white, produced in dense panicles 8 - 25 cm long. The fruit is an oblong dry drupe, with longitudinal ribs or narrow wings (the wings are absent in the related genus Styrax, whence the name Pterostyrax, "winged styrax").
