ARBORETUM ET FRUTICETUM BRITANNICUM. 



grows more rapidly, 

 attains a larger size, 

 and may be propa- 

 gated much more 

 readily by cuttings. 

 Both species ripen 

 seeds in Britain, in 

 fine seasons. P. oc- 

 cidentalis is readily 

 known from P. ori- 

 entalis, in the winter 

 season, by its bark 

 scaling off much less 

 freely, or, in young 



or middle-sized trees, scarcely at all ; and, in 

 leaves having red petioles, and '

the summer season, by its 

 being but slightly lobed (fig. 1732. a), in- 

 stead of being palmate like those of P. orientalis (fig. 173*^. b), which have 



green petioles, and by its globular catkins being nearly smooth, while those 

 of P. orientalis are rough.
