804 General Notes. [ October, 
Prothallogame and Phanerogame. The first is equivalent to the 
Thallophyta of many German botanists, but is treated very differ- 
ently by the author. The Myxomycetes are very properly placed at 
the lower end of the division, in a separate class, the Plasmodiez. 
In accordance with the rapidly growing idea first brought out by 
Cohn, the chlorophyll-bearing and chlorophyll free plants are not 
separated as Algz and Fungi; and the lichéns are considered an 
order constituting with the Sphzridez and Gymnoascidee the 
cohort Angiosporate, the latter very nearly equivalent to the 
Ascomycetes of botanists. The radical error, as it appears to Us, 
one. 
tantly to the ferns to warrant placing them between the Bryogam® 
and Prothallogame. ; 
The separation of the Phanerogame into three classes will 
strike every one as an innovation of doubtful value. Why the 
orthography of Gymnospermze should be changed to Gyno- 
spermz:, is also to be questioned, It will be observed that the 
cohorts and orders of the Angiosperme rank higher respectively 
than do the groups bearing these names in the system most 1) 
vogue in this country: the families (omitted for want of ee 
in Caruel’s system, are almost the equivalents of the orders © 
Bentham and Hooker, while Caruel’s orders are nearly equivalent 
to Bentham and Hooker’s cohorts.
