 P. insititia has often scarcely any spine, and then can only be d""^' 

 tinguished by the rather more pubescent leaves. In a., or the Sl^' 

 the fruit is small, globose, and very austere ; in /8., or the Bullace t,r' 

 it is larger ; and in 7. it is often longer than broad. "'

 whether_ truly distinct from the preceding is to us doubtful. As- 

 suredly m cultivation several of the differences usually assigned dis- 

 appear, such as the pubescence of the leaf; and as to the leafy nature 

 of the flower-buds, unless the upper figure in E. B. t. 706. be also 

 taken from the present species, it seems much alike in both.
