being, it is said, tree of heaven, hence the German name, Gotterbaum, tree of the gods.

Spec. Char.,§c. Leaves impari-pinnate; the leaflets coarsely toothed at the 
base ; the teeth glandulous on tne under side. (Dec. Prod.) A large tree. 
North of China. Height 50 ft. to 60 ft. Introd. 1751. Flowers whitish 
green, exhaling a disagreeable odour; August. Capsules like the keys of 
the ash, but smaller ; ripe in October. Decaying leaves brownish, but drop- 
ping with the first frost, without any great chance of colour. The leaflets 
often: separating from the petiole of the leaf, and leaving it for some weeks 
attached to the tree. Naked young wood 
rusty brown, without buds. 
The leaves on vigorous young trees are 
sometimes 6 ft. in length. The truit, which 
has been ripened at White Knights, resembles 
the keys of the ash, but is smaller. The tree 
grows with great rapidity for the first 10 or 
12 years, producing shoots from 3 ft. to 6 ft. 
in length at first. and attaining the height of 
15 or 20 feet in 5 or 6 years, in favourable 
situations. Afterwards its growth is much 
slower. It grows in any soil, though one that ff 
is light and somewhat humid, and a sheltered “XL 
situation, suit it best. In France, it is said to 
thrive on chalky soils, and attain a large size 
where scarcely any other tree will grow. It 
is readily propagated by cuttings of the roots. 194, Aildntus glandulosa.
