"Pterostyrax" (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 to 4-12 m tall, and have 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").Fritsch, P.
