12 THE BRITISH ROSES 
Baker's type-specimen of var. opaca, which is in Borrer’s her- 
barium at Kew. But for the existence of such species as R. leuco- 
chroa Desv. and var. evanida Chr., I should have much doubted 
this being a , stylosa form at all. Its prickles, though hooked, as 
in many Hu-canine, are slender from shortish bases, the upper 
ones quite slender and very unlike those of this group. The 
Rey. G. E. h between Ghilgrove and ieee aaa (not 
Kent as athtelt in se Monograph), and I have seen no Eaitier British 
specimens referable to this variety.
