Description
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
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
The tree is not known to be in cultivation in the West.
gollark: That sounds right.
gollark: I think they should just be treated as all the same, since it's not like you can generally get useful data out of the precise details of a NaN in most languages.
gollark: In JS, as far as I know, all NaNs are not equal to each other, so nothing bitpatterny going on.
gollark: It has `Map` now.
gollark: Well, "array".
