a greenish yellow colour; berries black, about the size of a pea; and the 
general appearance of the plant is that of 2. catharticus, of which it may 
possibly be only a variety. In 1833, there was a small plant of it in Loddiges’s 
arboretum. The wood is red, and is called sandal wood by the Russians.

dite or dicecious. Pedicels 1-flowered, aggre- 
gate. Calyxes acute. Fruit turbinate. (Don’s | 
Mill., ii. p. 32.) A deciduous shrub, grow- 
ing to the height of 8ft.; a native of North 
America, introduced in 1778; but not the R. 
dinifolius of Pursh. There are plants of this 
name in the nurseries, which, in London, cost 
ls. 6d.; at New York, 50 cents.

Peduncles twice bifid. Berries depressed, globose. (Don’s Miil., 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 4 
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., §c. Erect, twisted. Leaves oval- 
lanceolate, crenate-serrated, smooth, lineated with 
many parallel nerves. Flowers diccious, female 
ones with 4-cleft stigmas. (Don’s Mill., ii. p. 32.) 
A deciduous shrub, growing to the height of 4 ft., 
in the Alps, of Switzerland, Dauphiné, 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.
