The leaves are opposite, hard and leathery in texture, glossy dark green with a short yellow petiole the stalk attaching a leaf to the stem. It is capable of twisting the leaf to face the sun , variably unlobed or three-lobed (often on the same shoot). The flowers are yellow-green, produced in small pendulous corymbs a type of inflorescence in which the lower flowers have longer pedicels than the upper ones, creating a flat-topped appearance. .

A.k.a. a. velutinum van volxemii . Native to Azerbaijan, Georgia and N Iran, where it was discovered by Belgian nurseryman Jean van Volxem in the 1870s). A deciduous tree to 40m in the wild. In leaf it looks similar to A. pseudoplatanus, with which it can hybridise, but the leaves of A. velutinum tend to be larger, with longer, stout petioles. The two are however easily separated by their inflorescences a group or cluster of flowers arranged on a stem : in A. velutinum they are held erect, while in A. pseudoplatanus they are pendulous.

Formosan alder

A.k.a. a. maritima var. formosana, a native of Taiwan. Leaves are green with an elongated shape, pink when young then shiny green until they fall in autumn.
