with’ only very slight modification in the latter. These districts are 
illustrated by an excellent large folding map ; and Mr. Prestwich, the 
well-known geologist, furnishes its counterpart to show the county 
eoogy. Maps such as these add greatly to the value and clearness 
of a county Flora. We are furnished, as in the Floras of Hertford- 
shire, Cambridgeshire, Essex, and North Yorkshire, with separate lists . 
for each of the districts; the districts in which a species is ascertained 
to grow being enumerated, when it is mentioned, and the special stations 
which are given for the rarities being classified under the district initial 
etters, 
The personal observations of Messrs. Salmon and Brewer appear to 
relate principally to the chalk range and the country on the south of. 
it, but for the north they have had the benefit of Mr. Watson’s thirty 
years’ experience; and both for north and south a large amount of in- 
formation has also been obtained from other botanists, who have resided 
in or visited different parts of the county. The combination of these 
varied contributions gives us what is probably not far from a complete 
enumeration of the plants of each of the nine districts taken separately, 
so that now there are not many British counties the distribution of _ 
Species through which is registered more thoroughly. 
Mr. Brewer classifies the species according to the * London Catalogue." 
He gives the number of the flowering plants and Ferns of the county as 
984, but this is by counting a number of species not reckoned as species 
m the London Catalogue’—a way of reckoning which raises the total 
number of British plants to 1566. Mr. Watson’s estimate, in the 
th volume of the ‘Cybele Britannica,’ is 840 species for Surrey 
“gunst 1425 for the whole of Great Britain without Ireland. Of the 
: 20 species of more or less distinctly marked boreal range, only very 
AW Teach Surrey at all. The most notable instances of boreal Surrey 
Plants are Sagina subulata, Myrrhis odorata, Pyrola minor, Vaccinium 
E aryeocens, and the two species of Chrysosplenium, all of which appear 
be quite of rare occurrence. Mr. Watson states the number of 
generally diffused through Britain as 420. This leaves about as 
E Many tore for the Surrey plants of more or less distinctly marked 
4 M range in Britaiu, which is considerably above half the whole 
of our austral species. Perhaps nowhere in Britain have we
