About plant names...
Smooth alders are usually small, somewhat disheveled-looking trees, with many trunks and branches that
form a nearly impenetrable thicket. As a group, alders' most prominent feature is the
small cone-like fruits, which remain on the tree through the winter. They are common at the edge of
water, and in areas that are wet in the spring.
