a The following specific characters of this most intricate genus are taken 

 in every instance, where not otherwise mentioned, from specimens that are 

 the best authority for the E. Bot. species ; that is, from individuals gathered 

 in the lute Mr. Crowe's garden near Norwich, in company with Mr. Crowe 

 himself, or with Sir James Smith. If my characters differ in some measure 

 from those published by Smith, it will show how variable are these plants, 

 and how careful we ought to be in not multiplying the species unnecessari- 

 ly. Future observations, I think, will warrant the reduction of the present 

 very extensive list of British willows.
