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 “i 
scaling off much less P. occidentalis. 1732, P. orientalis, 
freely, or, in young 
or middle-sized trees, scarcely at all; and, in the summer season, by its 
leaves having red petioles, and being but slightly lobed (fig. 1732. a), in- 
stead of being palmate like those of P. orientalis ( fig. 1732. 6), which have- 
green petioles, and by its globular catkins being nearly smooth, while those 
of P. orientalis are rough.
