SOME BRITISH POTENTILLA-HYBRIDS. 
By tue Rev. E. 8. Marsnatt, M.A., F.L.S8. 
Some time ago Mr. W. H. Beeby (Journ. Bot. 1888, pp. 78, 79) 
gave the results of Herr Svanté Murbeck’s examination of various 
British Cinquefoils. He has since home good enough to forward for 
me a considerable series from the . H. Purchas’s herbarium, 
together with a few specimens of “ae own about which there was 
some doubt. The determinations indicate that these hybrids occur 
not unfrequently in the South and Midlands; and one which had 
not been detected at the time “ei the above- named paper was 
published has been added to our list. 
Herr Murbeck erage the name P, —— Neck. by a 
known from old time as Tormentilla nr =m ain this name 
specifically, after the absorption of the genus,” and probably 
most people will agree with him. * Indeed, the aides shuffling 
of names has become an intolerable nuisance.
