I follow Dr. Lindley’s classification so far as the adoption of the 
Alliances, the mode of sub-dividing the class Exogens, the admission 
of his class Dictyogens, and the general series of the orders,—ex- 
cepting that as I now propose to proceed no further than the Ferns, 
I have reversed the arrangement so as to leave the unfinished part at 
the end instead of at the beginning of my work. I differ from Lind- 
ley in rejecting his class Rhizogens, which, however, does not affect 
the Canadian Flora, in receiving the Ferns as a class under the name 
of Acrogens,—the Mosses and Hepatice being called Anophytes,— 
and in deeming it useful to reduce the seven classes thus admitted 
under three sub-kingdoms, which may, I conceive, be best named 
CryptoGAM&, MonocotyLEDONE#, DicoTyLEDONE#&. My gene- 
ral scheme of the vegetable kingdom would therefore stand thus :—
