alder (Alnus spp.; BIRCH FAMILY [Betulaceae]) Trees or shrubs with broad deciduous leaves.  Buds are notable for being stalked.  Staminate flowers in long (4-6") catkins, pistillate in a cluster with woody bracts that persist like miniature conifer cones long after the fruits have been shed.  Of the 3 Wisconsin species, speckled (tag) alder is probably the most familiar.  It is a coarse, weak-wooded shrub that forms dense thickets along northern Wisconsin streams.  The largest divisions of its doubly-toothed leaves are large enough to be considered lobes.  [027]
