REVISION OP THE BRITISH WILLOWS. 



and Forbes (next Salix prunifolia) seem to have had 

 thoughts of the relationship of Bicksoniana to Arbuscula forms. 

 Neither Smith's plate (in which the catkins are much too 

 young) nor Forbes's (in which the figured leaves resemble those 

 of nigricans) can be called very good. 



It is to be hoped that the wild state of Salix Bicksoniana will 

 be rediscovered.

Group 7. VlMlNALES. 



11. Salix viminalis, L. 



Though, like other species, liable to modification, S. viminalis 

 is, m Western Europe at least, one of the less variable willows, 

 and has no varieties worthy of distiuct names, though one or two 

 have been described. 



Amongst these are var. intricata, Leefe (distinguished chiefly 

 by the cloven, reflexed, and entangled stigmas), and var. stipularis, 



eefe ( with broader leaves and longer stipules). 



The 2 catkins vary a good deal in size. Most of the British 



n many of the foreign specimens I have seen have much 



8 ° r * er > but proportionately broader, catkins than in Wimmer's 



published examples, but apparently do not belong to Doll's var. 



ribreviata, in which the catkins are described as linear-oblong.
