General tree description

Alnus acuminata is native to the mountainous regions of Central and South America, and grows up to 25 metres tall with a pyramidal crown. It has smooth, grey-brown bark. Its leaves are oval, toothed, 5 to 17cm long and 3 to 7cm wide. The male flowers are pendulous catkins up to 12cm long, while the female flowers are green and resemble a small cone. They develop into 2cm long woody brown fruits containing many seeds, and they remain on the tree after the seeds disperse.

Alnus acuminata subsp. acuminata is one of three subspecies of Alnus acuminata. It has elliptic leaves and its natural range is limited to South America from Colombia and Venezuela, south to northern Argentina.
