1 A specimen somewhat intermediate as to pubescence between this species and K. allheoefulia has 

 been collected at Stockton, Marj'Iand, by Rusby. 



2 This name is arbitrarily altered to K. nlthcBifulia by Dr. Rusby (Mem. Torr. Club, v. 224), who, 

 overlooking the prior publication in Watson's Bibl. Index, cites the species as his own.
