NEW PUBLICATIONS. E 381 
In the six tables appended to his volume Mr. Clarke exhibits at one 
view the relations of the different families of each of these great divi- 
sions, and in the seventh table he brings together the divisions of the 
Exogens comprised in Tables 2 to 6, and so arranges them as to 
show their lateral relations to each other in their Monopetalous, Poly- 
petalous, Apetalous, and Gymnospermous forms. 
We cannot venture on criticism in detail of Mr. Clarke’s views. 
'There is in the volume so much novelty, and so much also from which, 
as we have hinted, we would be obliged to dissent, that we cannot here 
afford the space for such an investigation.. We would recommend our 
readers interested in such studies to peruse the volume itself, being 
satisfied that however much they may differ from the author, they will 
find matter for thought, and numerous important original observations 
scattered throughout the volume. 
Flora of Devon and Cornwall. By Isatan W. N. Keys. Reprinted 
from the ‘ Annual Report and Transactions of the Plymouth Institu-

Plymouth, 1866. — Ranunculacee to Geraniacee. 
This part contains the first 14 Orders of Professor Babington’s 
‘Manual,’ according to which work the Flora is arranged, and com- 
prehends the names and localities of 205 species, native and natura- 
lized ; numerous varieties are also enumerated. 
As the present is the first attempt at an entire Flora of this most 
interesting part of the kingdom, it can perhaps be scarcely expected to 
be complete ; yet we cannot but feel somewhat disappointed that the 
author has not endeavoured to supply a more exhaustive and accurate 
catalogue, and one more equal to the recently published county Floras. 
It is not pleasant to find fault with a work of this kind, but it must 
be said that the time has gone by when a short list of localities “ suffi- - 
cient . . . to meet the requirements of students and collectors ” is con- 
sidered all that is necessary to form a local Flora. Later efforts of 
the kind have been directed towards endeavouring to accurately show 
the past and present state of the vegetation of the county or district of 
which they treat, and to attempt in some way to account for it ; and in 
furtherance of this idea the district has been divided into smaller divi- 
‘sions, more or less numerous, founded in the best Floras on the natural
