ICONES MUSCORUM. 11 



SPHAGNUM CUSPIDATUM, Ehrh. var. 



Tab. 2. 



A forma normali tantummodo dififcrt : caule robustiori, foliis 

 ramulinis densius imbricatis pons sat numerosis instructis, 

 inflorescentia dioica. 



Sphagnum laricinum, Austin, Muse. Appalach. No. 31. 



Hab. Bogs, Sand-lake, New York, Peck. 



By its more closely imbricated leaves, either appressed or 

 slightly secund, its dense ramification, etc., this form rather re- 

 sembles Sphagnum laricinutn, Spruce, than any of the varieties 

 of *S'. cuspidatum. A close study, however, fails to disclose any 

 character which could separate it from this last species. It has 

 indeed a dioecious inflorescence ; but it is now recognized that 

 in the multiple forms of S. cuspidatum the inflorescence, al- 

 though more generally monoecious, is sometimes dioecious. As 

 remarked in the Musci Appalachiani, this form may be a hybrid 

 between >S'. subsecundum and S. cuspidatum.
