It is a large shrub or small tree reaching 4-8 m tall. The leaves are deciduous, 6-12 cm long and 4-7 cm broad. The flowers are white, 2-2.5 cm long, produced in clusters of 3-6 together. The fruit is a dry (non-fleshy) drupe with two wings down the sides; this distinguishes it from the other species of Halesia, which have four wings on the fruit.Huxley, A., ed. (1992).
