NOTES ON NORTH AMERICAN SPHAGNUM :— VII. 

 A. LeRoy Andrews 

 The Group Cuspidata Lindberg (Continued) 



16. Sphagnum recurvum Beauvois, 1805. An earlier name, S. intermedium 

 Hoffmann, 1795^ has been used by some authors for this species, but its status 

 is so uncertain^ that it has been rather generally and probably justly abandoned. 



1 Dr. Barnhart has called my attention to the fact that while the second volume of Deutsch- 

 lands Flora was not published until 1796, a portion containing Sphagnum came out shortly before 

 the close of I79S; cf. Hoppe, Botanisches Taschenbuch, 1796, 243ff. 



2 The whole question is discussed in considerable detail by Dusen in Sphagnaceernas utbred- 

 jiing, 42ff. 1887.
