illustrations of nearly all the North American species in Filices, 
ancl is a work much to be desired by the fern student, but is some- 
what expensive and nearly out of print. 
The recently published Vol. i of Britton & Brown’s “Illustrat- 
ed Flora of the Northern United States and Canada, Westward to 
the 102d Meridian,” contains outline drawings of all known species 
in Filices within the given limits. Meehan’s “Flowers and Ferns 
of the United States,” of which only four volumes were published, 
contains fine illustrations of many species, those of such as occur 
within our limits being noted in the preceding text. 
Those species of our Pteridoplivta which are also native to 
Great Britain, and they are many, will be found illustrated in Anne 
Pratt’s “Flowering Plants and Ferns of Great Britain” ; “English 
Botany,” Hooker’s “British Ferns,” and Newman’s “British 
Ferns.” 
The ferns of the world, or such as were recognized in 1874, 
will be found described in Hooker & Baker’s “Synopsis Filicum,” 
and continued in Baker’s “Summary of New Ferns,” (1892.) 
Those interested in fern culture will find much of interest in 
Kobinson’s ‘‘Ferns in Their Homes and Ours,” and in Shirley Hib- 
berd’s “Fern Culture Made Easy,” also in a series of articles by 
Robert T. Jackson in Garden and Forest, (Aug. and Sept , 1888.) 
A useful book for those interested in microscopical investiga- 
tions and in the study of the minute organization of this group is 
Campbell’s recently published “Structure and Development of the 
Mosses and Ferns.”
