This is by far the handsomest and most complete publication 
of its kind yet issued. It is printed on heavy paper, in large, 
clear type, and is remarkably free from errors of. spelling and 
typographical blunders, and gives us a list of North American 
Phanerogamia and Pteridophyta well representing our flora as it 
is known to-day. It appears that we have 164 species and 22 
varieties of Ferns and Ophioglossacee. One Lechea, L. mar- 
itima, Leggett, is omitted, and Z. thymifolia, Pursh., which 
this replaces, should be Z, thymifolia, Michx.,—the L. Nove- 
Cesaree of Austin; several other well-known species have 
been overlooked ; others, reported or described while Mr. 
Patterson’s work was in press, are also to be added. To 
provide room for such on the pages, there are spaces left after 
each of the larger genera. The arrangement of both species 
and genera is alphabetic. There must, in time, be many 
changes and additions, and we hope that Mr. Patterson’s venture 
may be so successful that he will feel warranted in issuing’ other 
editions. :
