2o8 ROSACEAE 



Stantoyi. Cookham. Ashley Hill. Crazey Hill. Bowsey Hill. 

 Wargrave. Sonning, &c. 



The leaves vary considerably in the depth of serration ; some 

 llowering specimens, which I sent to Dr. Boswell Syme, were, he say.s, 

 ' more deeply lobed than even specimens of so-called "P. scandica," but 

 they are without doubt P. Aria.' They are an analogous form (f. incisa) 

 to the variety perincisa, Borb. et Fer. of P. torminalis, which occurs in 

 Wychwood Forest, Oxfordshire. Perhaps the specimen reported as 

 P. scandica from Pangbourn by Prof. Babington may have been the 

 cut-leaved form of P. Aria. See Flora of Herefordshire, 124. 



P. Aria occurs in all the bordering counties.

Incog. ' Professor Babington mentions it from . . . Pangbourn. I have 

 carefully searched the Berks locality, but could find nothing but P. en- Aria,' 

 Syme, E. B. iii. 246. Prof. Babington also records it from Silchester, but, 

 according to Mr. E. Townsend, the locaUty is in Hampshire. 



At present my searcli for the plant in Berkshire has been unsuccessful.]
