Alnus rhombifolia var. bernardina Munz & I. M. Johnston

Trees , to 35 m; trunks often several, crowns spreading, open. Bark light gray, smooth, becoming darker and breaking into scales in age; lenticels inconspicuous. Winter buds stipitate, ellipsoid to obovoid, 3--9 mm, apex rounded; stalks 3--5 mm; scales 2, equal, valvate, sometimes incompletely covering underlying leaves, moderately to heavily resin-coated. Leaf blade narrowly elliptic to rhombic, rarely ovate, 4--9 × 2--5 cm, base cuneate to rounded, margins flat, finely serrate or serrulate, sometimes slightly lobed, without noticeably larger secondary teeth, apex acute or obtuse to rounded; surfaces abaxially sparsely pubescent to villous. Inflorescences formed season before flowering and exposed during winter; staminate catkins in 1 or more clusters of 3--7, 3--10 cm, stamens 2, or 4 with 2 reduced in size; pistillate catkins in 1 or more clusters of 2--6. Flowering before new growth in spring. Infructescences ovoid to nearly cylindric, 1--2.2 × 0.7--1 cm; peduncles 1--10 mm. Samaras broadly elliptic, wings narrower than body, irregular in shape, leathery.
