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.
