CHAP. LXXV. OLEA‘CER. O’RNUS. 124.5 
mucronate. (Don's Mill., iv. p. 57.) A tree, a native of 
North America, where it grows from 30 ft. to 40ft. high. It 
flowers in April and May, and was introduced in 1820. The 
difference between this sort and O. europz'‘a is so very slight, 
that we have no doubt of their being only one species. There are 
plants in the Horticultural Society’s Garden, in the arboretum 
of Messrs. Loddiges, and in the arboretum at Kew. The tree at 
Kew is grafted on the common ash; and fig. 1071. represents two 
views of the trunk, to a scale of lin. to 12 ft. The point where 
the scion was inserted in the stock is indicated at g, and the cir- wy 
cumstance that the former has enlarged nearly as much as the 
latter, is a proof that O. (e.) americana is a more robust-growing 
plant than O. europz‘a; but by no means that it is a different 
species. When no other mode can be obtained of rendering a 
tree gardenesque, that of giving the trunk an architectural base, 
by grafting a slow-growing on a fast-growing species, may be re- 
sorted to with success. Perhaps, also, the application of the 
art of grafting might be worth adopting for certain ornamental 1071 
trees to be planted in exposed situations; for the architectural base is 
strongly expressive of stability.

A tree, a native 
of Nepal, where it 
grows to the height 
of 30ft. or 40 ft. 
It flowers in April, 
and was introduced 
in 1822. There was a plant of this species in the Horticultural Society’s 
Garden, against the conservative wall, which died in the spring of 1836. 
Notwithstanding the tenderness of this species, we do not see any thing in 
that circumstance to prevent it from being merely a geographical variety of 
O’rnus americana or O. europe‘a. Though nothing can alter the nature 
of a plant, yet physical circumstances may to a considerable extent alter its 
habits, and even its constitution. The common European ash, if cultivated 
in the Himalayas, would, after many generations, in all probability become 
as tender as O. floribinda; and, in like manner, O. floribanda, after being 
cultivated for several generations in Europe, would in all probability become 
as hardy as O. europze‘a.
