 leaves 2*5 mm. x 1"75 at the base and '6 mm. at the apex, teeth 

 •2 mm. long, 3* mm. x 2- mm. near the base and '5 mm. near the

1, 2, 6-8.. 10-16. I. 



Found on the Continent and in North America. 

 Obs. — A very striking and one of our finest native species. 

 From B. fricrenafa (Wahlenb.) it is distinguished by its much larger 

 size, broader stems, greener colour, less deflexed leaves and its 

 oblong-quadrate stipules, which are coarsely and irregularly dentate. 

 Mr. Greorge Stabler has found on specimens collected on 

 Black Crag, Staveley, Westmoreland, flagella both branched and 

 bearing male catkins.
