Halesia macgregorii
 Halesia macgregorii is a species of flowering plant in the family Styracaceae. It is endemic to southeastern China where it grows at moderate altitudes of 700–1200 m. It is threatened by habitat loss. Recent genetic evidence suggests it is probably more closely related to the genus Rehderodendron than to other species of Halesia; it may be transferred to that genus in the future.It is a deciduous tree growing to 24 m tall with a trunk up to 45 cm diameter.
