Alder
K’ish
(a.k.a. Arizona alder)

Alternate arrangement of leaves on twigs

Alder is usually a streambank tree, although it can also grow as a large shrub. The leaves are simple, doubly serrate, and heavy-veined. The male flowers are structured in catkins and the female flowers are surrounded by bracts which harden into a woody remnant (called by some an ament, and by others a strobilus) which resembles a small cone. The young branches can be longitudinally ridged.
