Ulmus wallichiana var. tomentosa was identified by Melville & Heybroek after the latter's expedition to the Himalaya in 1960.

Description[edit]

The tree is very similar to Ulmus wallichiana subsp. wallichiana, but distinguished by young stems and lower surfaces of leaves densely white-tomentose; the samarae are uniformly hirsute.

Pests and diseases[edit]

The species has a high resistance to the fungus Ophiostoma himal-ulmi endemic to the Himalaya and the cause of Dutch elm disease there.

Cultivation[edit]

The tree is not known to be in cultivation in the West.
