Ulmus wallichiana subsp. wallichiana was identified by Melville and Heybroek after the latter's expedition to the Himalaya in 1960.
A deciduous tree growing to 30 m with a crown comprising several ascending branches. The bark of the trunk is grey-brown, furrowed longitudinally. The leaves range from 6–13 cm long by 2.5–6 cm broad, elliptic-acuminate in shape, and with a glabrous upper surface, on petioles 5–10 mm long. The samarae are orbicular to obovate, 10–13 mm in diameter, on 5 mm pedicels, the seed central.
The tree has a high resistance to the fungus Ophiostoma himal-ulmi endemic to the Himalayas and the cause of Dutch elm disease there.
The tree is not known to be in cultivation beyond the Himalaya.
