The tree grows to a height of up to 20 m in height. Its bark is thin and gray-brown, smooth when the tree is young but eventually becoming finely scaly. The twigs are slender and slightly zigzag; they are lightly reddish-brown. The flowers are up to 5cm long and are grouped in 30 cm panicles. They appear in spring and early summer and last up to two months. They are then followed by woody seed pods, about 5 cm in diameter and winged seeds.
