Alnus oblongifolia
Also called Mexican alder, New Mexican alder, Oblong Leaf Alder
Arizona alder is a large deciduous tree, up to about 22 m, native to riparian streamsides and mountain canyons in Arizona, New Mexico, and northern Mexico. It is best suited to cool, moist sites with reliable water, and it is rarely grown outside its native range.
Alnus oblongifolia (Arizona alder) is a large alder growing up to 72 feet (22 m), from the southwestern United States and northern Sonora, Mexico. It grows across Arizona into western New Mexico mountain ranges. In central Arizona its range extends across the transition zone to the White Mountains region of eastern Arizona–western New Mexico border.
Besides the range extension from central Arizona, elsewhere in New Mexico it occurs only in scattered mountain range locales. In southern Arizona south of the Mogollon Rim, also in two mountain regions, and in neighboring Sonora in regions at the north of the Sierra Madre Occidental cordillera near Arizona's southeast Madrean Sky Island ranges of sky islands. Isolated mountain locales also occur in a region of southwest Chihuahua and neighboring northwest Durango, part of the eastern Sierra Madre Occidentals.
