 W. vi ridula nitida; they may appear in several pockets. 



No. 62. Rhacomitrium microcarpum (Bedw. p. p.) B. 8. 

 This number was sent out as Rhac sudeticum. The error was due to a mixture of 

 these two species in the material sent me; most of this proved to be lllwc. m/rmmr- 

 pum. Dr. Grout, who furnished this lot collected by Mr. W. W. Eggleston, states 

 that tne locality should be "Mt, Washington, N. H."

 better be referred to this variety.
