7. Alnus viridis (Chaix) de Candolle in J. Lamarck and A. P. de Candolle, Fl. France, ed. 3. 3: 304. 1805.

Betula viridis Chaix, Pl. Vapinc. 70. 1785; Alnus alnobetula (Ehrhart) K. Koch; A . ovata (Schrank) Loddiges

Shrubs , spreading to compact, to 10 m. Bark smooth; lenticels scattered, conspicuous to inconspicuous, small, mostly unenlarged. Winter buds nearly sessile, ovoid, apex acuminate; stalks usually not over 1 mm; scales 4--6, unequal, imbricate. Leaf blade broadly to narrowly ovate or elliptic, 3--11 × 3--8 cm, base rounded, obtuse, or cuneate, sometimes nearly cordate, margins serrulate to coarsely doubly serrate, apex acute to rounded; surfaces abaxially glabrous to tomentose, lightly to heavily resin-coated. Inflorescences: staminate catkins in 1 cluster of 2--4, formed late in growing season before flowering and exposed during winter; pistillate catkins in 1 or more clusters of 2--10, formed season before blooming, enclosed in buds during winter, exposed with new growth in spring. Flowering with new growth in spring. Infructescences ovoid to ellipsoid or nearly cylindric; peduncles relatively long, thin. Samaras elliptic to obovate, wings wider than body, membranaceous.

Subspecies 4 (3 in the flora): southern arctic, subarctic, and n mountainous regions, North America and Asia.

Alnus viridis is distinctive among the alders in its essentially sessile buds with several imbricate scales and in its relatively long, thin, infructescence peduncles. Like the birches, only the staminate catkins are exposed during the winter prior to blooming.
