Winter buds brown, ovoid, 2–4 mm, glabrous, apex obtuse to acute. Stipules linear to linear-lanceolate, 5–10 × 1.5–3 mm, margin entire or slightly dentate. Leaves on short branchlets sessile and in clusters, those on long branchlets often solitary and alternate; petiole 4–7 mm, glabrous; leaf blade narrowly oblong, oblong-lanceolate, or lanceolate, 2.5–6 × 0.8–3 cm, both surfaces glabrous, base narrowly cuneate to attenuate, margin minutely and shallowly obtusely serrate, apex acute to ± obtuse.
