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").[1][2][3]

Species
  • Pterostyrax burmanicus W.Wsm.
  • Pterostyrax corymbosus Siebold & Zucc. - Japan and China
  • Pterostyrax hispidus - Japan
  • Pterostyrax psilophyllus Diels ex Perkins - China

The species names are frequently given with feminine gender ("corymbosa", etc); however, the genus is correctly of masculine gender.[2]
