Arizona Alder
Alnus oblongifolia
« Back to citizen participation project
A spreading tree with a single trunk and distinctively veined and sawtooth-edged leaves, Arizona Alder is most often found in the rocky mid-elevation canyons. The bark of younger trees is smooth and gray, but this becomes rough with age. The female flowers are produced in small pine cone-shaped structures (called cones) that turn reddish-brown in age but persist for at least a year, while the male flowers are produced in catkins that quickly disintegrate after flowering.
