to any of these forms', that specific name will have to be re- 
tained for the combined species which may be characterized by 
the following description :

Additions to the Habitats of N. American Sphagna. 
For several years past the writer has made excursions into 
the southern parts of New Jersey in order to examine and note 
the distribution of the various species of Sphagnum, and the most 
important results are herewith given. The varieties new to this 
country are indicated in small caps. 
Sphagnum Portoricense, Hampe, occurs in ponds at Pleasant 
Mills, Atlantic Co.; at Atsion & Brown’s Mills, Burlington Co. ; 
Dr. G. Martin, of West Chester, Pa., while in Florida, during 
the month of March, this year, sent me a lot of Sphagna for 
identification, amongst which I was fortunate enough to detect a 
number of plants of 8, imbricatum, Hornsch. This species has 
not, to my knowledge, been heretofore found south of New 
ersey. 
_ Sphagnum papillosum, Lindbg., is found in bogs near Toms 
River, Ocean Co.; Atsion and Quaker Bridge, Burlington Co., 
and in fruit near Newfield, Gloucester Co.

Maa am under obligation to my friend Mr. A. B. Seymour, of Cambridge; 
seta oF aid in establishing the nomenclature of this subject, as well as for 
many of the specimens from which the above descriptions are taken.
