limitations of a species which provides for all intergrading forms and 
their variations. 
A list of the material used in my examinations may be of interest, 
as showing the extensive range and cosmopolitan character of this 
species. 
. Specimens, including all forms, from various parts of New Eng- 
land, from my own collections and those of John Robinson, Walter 
Deane, Mr. Pringle, and others; beside which I have had access at 
various times to the fine collections of Professor Eaton, Mr. Faxon, 
and the especially valuable collection (now in possession of the Appa- 
lachian Mountain Club) of the late Mr. E. H. Hitchings; to say 
nothing of the numerous specimens which I have identified, from time 
to time, for various collectors and correspondents. 
2. Specimens from New York and the Middle States, from the col- 
lections of Mrs. Barnes, Rust, Myers, Gifford, and other members of 
the Syracuse Botanical Club; also collections of E. S. Miller (Long 
Island), J. H. Redfield (Pennsylvania), Dr. Schneck (Illinois), and 
others. One of Mrs. Barnes’ North Woods plants is remarkable for 
the small, rounded, almost lunate segments (as in Alabama plants), 
and the very nearly sessile sterile divisions, the stalk of which is shorter 
than in Chapman’s Florida specimen. Between this and her larger 
plants, that approximate Californian australe, there is every conceivable 
Variation, 
3. Specimens from Canada: Prince Edwards Island, north shore 
of Lake Superior, Northwest Territory and British Columbia, from the 
collections of Professor Macoun. 
4. Specimens from Alaska (7urner), Washington soa i Cali- 3 
fornia (Miller), and Mexico (Pringle). !

in Gray Hew), South Carolina, in Herb. Mass. Hort. ort. Soc.,
