Ulmus wallichiana var. tomentosa |
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.
The species has a high resistance to the fungus Ophiostoma himal-ulmi endemic to the Himalaya and the cause of Dutch elm disease there.
The tree is not known to be in cultivation in the West.
