NEW BOTANIST’S GUIDE AND GEOGRA- 
PHY OF BRITISH PLANTS. 
Two highly interesting works, which 
promise to be eminently useful to the Bri- 
tish Botanist, have just appeared from the 
. pen of H. C. Watson, Esq., the one enti- 
tled * Remarks on the Geographical Dis- 
tribution of British Plants, chiefly in con- 
| nexion with latitude, elevation, and cli- 
..  mate"—the other, “ The New Botanist's 
Guide to the localities of the rarer Plants 
- of Britain, on the plan of Turner and Dill- 
wyn's Botanist's Guide, Vol. L, England 
_and Wales.”—In regard to the first of these 
publications, it contains, as may be ex- 
.. pected from the author of “ Outlines of 
- the Geographical Distribution of British 
Plants," a mine of valuable information, 
partly the result of Mr. Watson's many 
personal observations in various, and espe- 
cially the mountainous, districts of Great 
Britain, and partly derived from the com- 
munications of others, and from consulting 
. animmense number of works bearing upon 
his subject. The following list of contents 
will convey some idea of the variety of to- 
pics treated of in this book.—I. Remarks 
on the Physical Geography of Britain; 1. 
Extent and Position; 2. Elevation of Sur- 
: face ; 3. Climate, Temperature, Rain, Pro- 
 Bress of the Seasons, indicated by that of 
_ Vegetation. —II. General Remarks on the 
Flora arid Vegetation of Britain; 1. Nu- 
merical Estimate; 2. Botanical Character. 
| MH. Remarks on the Data for determin- 
: E the distribution of Plants in Britain.— 
Iv. Remarks on the Distribution of Plants 
in Britain; 1. Distribution in Ascending 
: Regions— Region of the Plains, Upland 
Region, Median "Region, Subalpine Re- 
connexion with Altitude, in the High- 
lands of Scotland, in Cumberland ; 3. Dis- 
: : A work, indeed, only printed for private circula- 
which, from the liberality of Mr. Watson, 
desire to promote the study of this important 
i ee y; is in the possession of almost every 
One who feels an interest in the subject.

tribution, in connexion with lines of Lati- 
tude and Longitude; 4. Distribution, in 
connexion with Geographical or Local 
Position.—V. Remarks on the Distribu- 
tion of Plants over other countries.—Then 
follows an Appendix on the following 
subjects :—No. I. Table, indicating the dis- 
tribution of Plants within Britain.—No. II. 
Table, indicating the Geographical Exten- - 
sion of British Plants.—No. III. List of the 
most generally distributed Plants, as shown 
by the local Floras.—No. IV. List of Sy- 
nonyms in “ Lindley’s Synopsis of the 
British Flora."—No. V. List of the Natu- 
ral Orders and included Genera, for the 
convenience of persons chiefly conversant 
with the Linnean Classification.—No. VI. 
Index to the Genera in Nos. I. and II. 
Mr. Watson's ** New Botanist's Guide" 
is a work of immense labour, and ought to 
be in the hands of every one who studies 
British Plants. By means of numerous 
abbreviations, in regard to authorities for 
the stations, the whole of the rarer plants 
(omitting the Cryptogamie) of England 
and Wales, are comprised in one small 
closely-printed volume, which the traveller 
can easily carry in his pocket on his excur- 
sions. The arrangement is two-fold—Ist, — 
according to counties, as in Turner and 
Dillwyn’s admirable Botanist’s Guide, 
(which is indeed the model of the present 
book,) beginning with Cornwall, and pro- 
ceeding northerly; while, under each 
county, the species are arranged according 
to the Natural Orders; and 2ndly, there is 
a list of all the species, arranged according 
to their natural affinities, each of which is 
followed by an enumeration of the counties 
in which they are found. The author has 
derived great assistance in compiling this 
work from the many local Floras that have 
been recently published, and still more, 
perhaps, from the numerous communica- 
tions he has received, both of specimens — 
and unpublished Catalogues. :
