Alnus jorullensis, commonly known as Mexican alder, is an evergreen or semi-evergreen alder, native to eastern and southern Mexico, Guatemala and Honduras.[1][2] Although previously reported from the Andes,[3] further collections showed these to be the similar species Alnus acuminata, commonly found in South America.[2]

Alnus jorullensis is a medium-sized tree growing to 20–25 m tall. The leaves are obovate to elliptic, 5–12 cm long, somewhat leathery in texture with a serrated margin and glandular on the underside. The flowers are wind-pollinated catkins, produced in early spring.[4]

It is used for ornamental planting in warm temperate areas such as southern California.
