Eucommia grows to about 15 m tall. The leaves are deciduous, arranged alternately, simple ovate with an acuminate tip, 8-16 cm long, and with a serrated margin. If a leaf is torn across, strands of latex exuded from the leaf veins solidify into rubber and hold the two parts of the leaf together. The flowers are inconspicuous, small and greenish; the fruit is a winged samara with one seed, very similar to an elm samara in appearance, 2-3 cm long and 1-2 cm broad.
