REVIEWS. 
The introduction comprises an able account of the topography, 
geology, and drainage of the county, and a full description of the 
seven botanical districts which are based on the river drainage. To 
each of these districts is added a full list of the more noticeable 
plants that are peculiar to the district. To this are also added obser¬ 
vations on the meteorology and temperature of the county, followed 
by the plan of the Flora, list of books, MSS., etc., quoted in the 
work, principal Herbaria quoted, and list of principal persons who 
have contributed notes or rendered assistance in the preparation of 
the Flora. 
The Flora proper, which occupies some 366 closely-printed pages, 
then follows. In this the author gives the localities for each district 
of the more local plants, also frequent personal notes on their special 
peculiarities, and, what is most interesting, copious notes from the 
older authorities and from the numerous works that have been con¬ 
sulted in compiling the work ; noticing, also, in many instances, the 
occurrence of the plant in the contiguous counties of Berks, Bucks, 
Warwick, Northants, and Gloucester. This is followed by a careful 
summary, giving the classes of citizenship, from which we find that 
the native plants of Oxfordshire number 818 species.

About 310 varieties have also been noticed. 
Under the head of aliens and casuals the author has probably 
included several plants scarcely worth noting in a Flora. The following

Comparative notices are also given of the contiguous counties, by 
which we find that 85 species occur in Warwickshire that have not 
been found in Oxfordshire, whilst Oxford has 88 species not at present 
recorded for Warwickshire
