Alnus nitida, the west Himalayan alder, is a species in the genus Alnus, native to Pakistan, the western Himalayas, and Nepal. It is a tree reaching 20 to 25 m, preferring to live along the banks of rivers. It is used locally for timber and firewood, and as a street tree. The bark is used in some places for tanning and dyeing purposes. It grows well in heavy, clay soils and tolerates infertile soils. The leaves are thin, oval to ovate, 3-6 inches long and 2-3 inches wide. Female flowers appear first, followed by male catkinss in September to October, which may be up to 19 cm long. The fruits are woody cones, typically 2.5-3.5 cm long.
