It is a deciduous tree growing to 15–25 m tall, with similar glossy green cordate leaves 5–15 cm long. The flowers are catkins, the male catkins very slender, 8–15 cm long, the female catkins small, maturing into a woody cone-like fruit 2–3 cm long containing numerous small winged seeds.
Two varieties have been recorded:[3]
- Alnus subcordata var. subcordata C.A. Mey.
- Alnus subcordata var. villosa (Regel) H.J.P.Winkl
Uses
It is a commercially valuable species with "widespread application in timber and furniture industries".[2] It has a calorific value of about 4.6 cal/g.
