Alnus rugosa, Spreng. Smooth Alder. Shrub, to 25 ft.: young branchlets pubescent or nearly glabrous: lvs. ovate or broadly elliptic to obovate, acute or obtuse, 2-5 in. long, doubly serrate and often slightly lobed, beneath covered more or less with brownish pubescence or glabrous: cones 4-10, the upper sessile, the lower short-stalked, ovoid, about 1/2 in. long. E. N. Amer. Mx. 3:4. Var. serrulate, Winkl. (A. serrulata, Willd.). Branchlets glabrous or nearly so: lvs. usually obovate, obtuse, finely and doubly serrulate, glabrous or nearly glabrous beneath. Em. 248.—By most European botanists this variety is considered a distinct species, but, though the extreme forms seem quite distinct, they are connected by all kinds of intermediate forms. In flower, A. rugosa is easily distinguished from A. incan by the pistillate catkins which are upright in /1. rugosa, nodding in A. incana. CH
