CHAP. XXXV. RHAMNACEX. RHA’MNUS. 535 
A deciduous shrub, growing to the 
height of 6 ft., in rocky and gravelly 
situations, near the rivers of Mon- 
golia and Siberia. Introduced in 
1823. It delights in a warm situ- 
ation; and in cold and humid 
places, Pallas observes, it is never 
met with. The wood, on account 
of its hardness and red colour, is 
used by the Mongols for making 
their images ; and the berries, when 
macerated in water, afford them 
a deep yellow colour. The plant, 
in its wild state, is a prickly bush; 
but, when cultivated, the spines 
no longer appear. There is a 
small plant of this species in the garden of the London Horticultural 
Society; and another in the arboretum of Messrs. Loddiges.
