292 Bibliographical Notice. 
has been surveyed afresh, and the distribution of the plants is sepa- 
rately exhibited in a table, where each species is traced through the 
eight districts into which the county has been divided for botanical 
purposes; these districts are further elucidated by some clear topo- 
graphical remarks and a serviceable map. All descriptions of genera 
and species are intentionally omitted, as out of place in a local Flora, 
but room is given for the ‘‘ kind of places” where the plant grows, 
its duration, and period of flowering. Then follow the localities, 
arranged under their proper districts; and here the stations which 
rest upon ancient authority only, are distinguished by being printed 
in italics. 
Great attention has been paid to the introduced plants; and, in 
addition to the recognized marks of possibly (+) and certainly (*) 
introduced, we have for the first time a separate brand ({) reserved 
for the intermediate cases of “ probably naturalized.” Several of 
the “colonists,” or weeds of cultivation, receive the brand of “ pos- 
sibly introduced ;”’ and, while we think this will be acknowledged as 
a step in the right direction, we could have wished to have seen the 
mark of exotic origin even more freely bestowed on this class. 
Arenaria leptoclados (Guss), Lotus tenuis (Sm.), and Triticum 
pungens (Pers.), now appear as species. The last, Godron (Flore de 
France, iii. p. 606) has already noticed as British; and there is 
reason for believing that the late Mr. E. Forster considered he had 
gathered it in Essex. Some alterations also occur among the Rudi, 
about which we are promised more information when Mr. Babington’s 
long-expected Monograph appears. In other respects, the arrange- 
ment and names correspond with the fourth edition of the ‘ Manual.’ 
In an Appendix occur some valuable critical remarks, amounting 
to so many distinct essays: upon Thalictrum flexuosum and T\. saxa- 
tile ; upon two plants confounded under the name of Papaver dubium; 
on Viola canina, Linn. ; on three forms of Arenaria serpyllifolia ; 
on several Brambles; on Serrafaleus ; and on Triticum. 
The paper on the Vegetation of the Fens is extremely interesting ; 
so is the list of lost plants, which amount to nearly fifty species ; 
among these, Sonchus palustris, Senecio palustris, Sturmia Leselii, 
and Caucalis latifolia are the most remarkable. 
The last few pages are devoted to the enumeration of such plants 
as find (within Great Britain) their western, northern, or southern 
limit in the county ; and the negative features of the Cambridgeshire 
flora are illustrated by a comparison with the list given in the sixth 
chapter of the ‘ Cybele Britannica’ (vol. iv.), from which it appears 
that out of the 718 species most widely distributed in Britain, 61 are 
absent from Cambridgeshire. 
Enough has been said to show the general plan and arrangement ; 
- those who wish for details respecting the species must refer to the 
work itself. We are sure that Mr. Babington’s volume will be highly 
appreciated, as it deserves to be most carefully studied, especially by 
those who are engaged in similar labours. Would that we had many 
other such County Floras!
