The Ulmaceae (/ ʌ l ˈ m eɪ s i /) are a family of flowering plants that includes the elms (genus Ulmus), and the zelkovas (genus Zelkova). [3] Members of the family are widely distributed throughout the north temperate zone, and have a scattered distribution elsewhere except for Australasia.
The tree has a high resistance to the fungus Ophiostoma himal-ulmi endemic to the Himalaya and the cause of Dutch elm disease there. However, U. wallichiana was found to be one of the most preferred elms for feeding and reproduction by the adult elm leaf beetle Xanthogaleruca luteola [4] and highly preferred for feeding by the Japanese beetle Popillia japonica [5] in the United States.
A photograph of the tree [78] can be found (plate 402) in Elwes & Henry's Trees of Great Britain & Ireland, published in 1913, wherein it is identified as U. nitens (U. minor subsp. minor).

Elms, hickory, and ash all have remarkably hard, tough wood, making them popular for tool handles, bows, and baseball bats. Chinese elm is considered the hardest of the elms. Chinese elm is said to be the best of all woods for chisel handles and similar uses due to its superior hardness, toughness, and resistance to splitting.
Elms are deciduous and semi-deciduous trees comprising the genus Ulmus in the family Ulmaceae. They are distributed over most of the Northern Hemisphere, inhabiting the temperate and tropical - montane regions of North America and Eurasia, presently ranging southward in the Middle East to Lebanon and Israel, [ 1 ] and across the Equator in the ...
In California 'Valley Forge' has also been found to be susceptible to leaf curling aphids (Eriosoma sp.) which produce honeydew [2] The cultivar is only moderately preferred for feeding by the Japanese Beetle Popillia japonica , [ 4 ] but the species as a whole is the most susceptible of all the elms to verticillium wilt .
Atinia Variegata' is also found among the elms lining the Avenue of Honour at Ballarat, while approximately 50 trees grow at The Nook, Sunbury, Victoria. [21] There are two mature trees in the Royal Tasmanian Botanical Gardens, Hobart. [22] In the United States, a specimen in Portland, Oregon, has been designated a 'Heritage Tree'. [23]
Ulmus rubra is a medium-sized deciduous tree with a spreading head of branches, [4] commonly growing to 12–19 metres (39–62 feet), very occasionally over 30 m (98 ft) in height.
