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 700–1,200 m. It is threatened by habitat loss.[1] [2] 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.[3]
It is a deciduous tree growing to 24 m tall, with a trunk up to 45 cm diameter. The leaves are 5–13 cm long and 3–4.5 cm broad, with a petiole 5–10 cm long. The flowers are pendulous, 1.5 cm long, with four white petals. The fruit is a dry drupe 2.5–4 cm long and 2–3 cm diameter.[1]
