lY. SECTION PIMPINELLIFOLLE HYBRID.E. 



It is extremely difficult to segregate these hj'brids into their 

 correct parentage. The very state of hybridity obscures the Group 

 characters, still more the specific or varietal ones, so that it is quite 

 probable that some of the form names, and more so tliat some of the 

 specimens have been referred to the wrong Group. 



1. Group PiMPixELLiroLiiE x Yillosj?,. 



R. INTOLUTA Sm. stem armature mixed, leaflets hairy and bi- 

 serrate, peduncles glandular-hispid, and styles \dllous. 1 use the 

 name as an aggregate only, to cover all the following forms.

 glabrous above, thinlv hairy beneath, sepals usuall}' entire. Y.c. 15, 

 57, 64, 65, 90, 100. ^
