Sj)ec. Char., <$-c. Leaves impari-pinnate ; the 159 



leaflets coarsely toothed at the base; the 

 teeth glandulous on the under side. (Dec. 

 Prod., i. p. 89.) A deciduous tree of the 

 first rank, introduced from China in 1751, 

 and growing to the height of 60 ft. or up- 

 wards. In some years, the tree is said to 

 bear only male flowers; and L'lleritier 

 states that only twice in 10 years it bore 

 both male and female flowers at the same 

 time in France. In his time, it had pro- 

 duced fruit in the Jardin dcs Plantes at 

 Paris, and in the Botanic (iardcn at Ley- 

 den ; but in both cases it was immature. 

 It has since, however, produced perfect 

 fruit, from which plants have been raised. 

 It has also ripened fruit at White Knights in England. The flowers, which 

 appear in August, are in large, upright, rather compact panicles, of a whitish 

 green colour, and exhale a di.sagreeab!e odour. The fruit resembles the 

 keys of the ash, but is smaller. The leaves are from 3 ft. to C ft. in 

 length ; those produced by vigorous suckers, in favourable situations, attain- 

 ing tiie latter dimensions. The tree grows with great rapidity for the first 

 10 or ]-2 years, producing shoots from 3 ft. to G ft. in length at first, and 

 attaining the height of loft, or '20ft. in 5 or G years in favourable situ- 

 ations. Afterwards its growth is much slower. The wood is of a fine 

 grain ; it has a satiny aspect, and is hard, and w ell fitted for the purposes 

 of cabinet-making. The tree has a noble appearance when clothed with 

 leaves; and its gigantic boughs and shoots, and its straight, erect, thick
