 sidered as a species of flhus, whence the French name ; and the meaning of the aboriginal word 

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

Spec. Char.,S,-c. Leaves impari-pinnate ; the leaflets coarsely toothed at the 

 base ; the teeth glam.lulous 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 G 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 lenoth at first, and attaining the heidit of I 

 15 or 20 feet in 5 or G years, in favourable < 

 situations. Afterwards its growth is much 

 slower. It grows in any soil, though one that ' 

 is light and somewhat humid, and a sheltered 

 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. .4 ..,/. gianduiosa.
