(3). Metaspermz, which includes all those plants formerly 
classed under Angiosperme, or, in the words of the author, ex- 
amples of the Metaspermz may be selected from the great mass 
of plants which contain their seeds in a closed “ovary,” better 
named “carpellum.” These, then, are alone what have been con- 
sidered by the author in the present work. Even our old and ap- 
parently firmly established friends the Mono- and Dicotyledones 
have been transferred to a more subordinate position than they 
once held, and we find the metasperme divided primarly into 
Chalazagamez, consisting of the single genus Casuarina, and Poro- 
gamez, which includes all the other Metasperme and in which 
the Mono- and Dicotyledons are at last permitted to figure as sub- 
divisions. The former are not subject to any further subdivis- 
ions, but the latter are arranged, in accordance with the morphol- 
ogy of the perianth into Archichlamydaz [ Polypetale and Apeta-_ 
lz], and Metachlamydee [Gamopetale]. The skeleton scheme 
of classification would thus appear : 
A. Protophyta. 
B. Metaphyta. 
I, GAMOPHYTA. 
II. SPOROPHYTA. 
(1) THALLOPHYTA, 
(2) ARCHEGONIAT#, 
(3) METASPERMé. 
Metasperme., 
(a) Chalazagamec. 
(b) Porogamez. 
1, Monocotyledones. 
2. Dicotyledones. 
Archichlamydez. 
Metachlamydez. 
Under this arrangement the list begins with Porogamee 
(Monocotyledones), Family Typhacee, Genus Zypha, Species 7. 
latifolia, Linn. and terminates with Family Composite, Genus 
LTieracium, Species H. Canadense, Michx. The total number of 
families enumerated is 106, genera 407, and species and varieties 
1,174. 
The number of changes in long established names is neces- 
sarily considerable. Most of them have, however, already been 
adopted by other progressive botanists and have appeared in print
