The elm Ulmus wallichiana subsp. xanthoderma was identified by Melville and Heybroek
after the latter's expedition to the Himalaya in 1960.[1]
The tree is of more western distribution than subsp. wallichiana, ranging from Afghanistan to Kashmir.[2]

The branchlets become orange- or yellow-brown, glandular at first, not hairy. The leaves range from 5.6–14 cm long by 3–7.5 cm broad, elliptic-acuminate in shape,[3] and with a glabrous upper surface, on petioles 7–10 mm long. The inflorescence is slightly glandular, almost glabrous. The samarae are orbicular to obovate, with a few glandular hairs; the seed central.[1][2]
