''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 tall, with alternate, simple ovate leaves long and broad. The flowers are white, produced in dense panicles 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.
