a greenish yellow colour j berries black, about the size of a pea; and the 

 general appearance of the plant is that of R. catharticus, of which it may 

 possibly be only a variety. In 1S33, there was a small plant of it in Loddiges's 

 arboretum. The wood is red, and is called sandal wood by the Russians.

 Peduncles twice bifid. Berries depressed, globose. (Don's Mill., ii. p. 32.) 

 A deciduous shrub, growing to the height of 8 ft. ; a native of North 

 America, from Canada to Virginia, on dry hills, near rivers; producing 

 its green flowers in June and July, which are succeeded by small, round, 

 black berries. Introduced in 1810. This sort, and some of the others, 

 may; possibly be only seminal varieties, or natural hybrids; for, in a 

 genus in which there are so many species, it is to be expected that acci- 

 dental cross fecundation will occasionally take place. From whatever 

 source, however, a distinct form is produced, it can always be continued 

 in gardens by propagation by extension ; and, so long as mankind have 

 wealth, intelligence, and leisure to admire the varied productions of 

 nature, the greater the number of these varied productions, the more 

 ample will be their source of enjoyment.

Spec. Char., Sj-c. Erect, twisted. Leaves oval- 

 lanceolate, crenate-serrated, smooth, lineated with 

 many parallel nerves. Flowers dioecious, female 

 ones with 4-cleft stigmas. (Don's Mill.,\\. p. 32.) 

 A deciduous shrub, growing to the height of 4 ft., 

 in the Alps, of Switzerland, Dauphine, and Car- 

 niola. Introduced in 1752. The flowers are 

 greenish, and produced in May and June, and 

 the berries black. This is a very distinct species, 

 and remarkable for its twisted leaves. There is 

 a strong plant of it in the arboretum of Messrs. 

 Loddiges, and one in the garden of the Horticul- 

 tural Society, which, in 10 years, has attained 

 the height of 8 ft., and the character of a small 

 tree.
