2 THE FLORA OF WARWICKSHIRE. Jan., 1891. 
thousand square miles. Although it is in the very centre of 
England, and is the watershed between Thames, Trent, 
and Severn, its highest point only attains a height of 855 
feet above sea level, so that it all belongs to the warmest 
(inferagrarian) of the six zones of climate into which the 
surface of Britain is divided by geographical botanists. Mr. 
Bagnall gives a map of the county, and, to insure its thorough 
exploration, has divided it into ten districts founded on the 
river drainage, and worked each of these as a distinct unit. 
The short introduction contains a sketch of each of these 
districts ; a brief but sufficient sketch of its Geology by a 
promising young resident geologist, Mr. Bernard Badger, 
B.A. ; and a note upon its Temperature and Rainfall, 
which latter, of course, present no striking feature of 
individuality. 
The great bulk of the book is occupied by an 
enumeration of the plants, the distribution of which 
is traced through the ten drainage districts, and abundant 
detail given about the special localities of the rarities. 
Rubi are very abundant in Warwickshire, and Mr. Bagnall, 
who is a pupil of Bloxam, has worked out the local 
forms very carefully, and sent sets of specimens to the 
herbaria of Kew and the British Museum. The Flowering 
Plants and Ferns occupy 328 pages. The eighth edition of the 
London Catalogue is followed as a standard of nomenclature 
and species limitation. The Flowering Plants and Vascular 
Oryptogamia have been worked so thoroughly that it is not 
likely that many additions will be made to this record in the 
future. The Mosses occupy forty-eight pages, and 236 species 
are recorded. Here, again, it is not likely that many 
novelties remain undiscovered. The Hepaticse have been 
worked less thoroughly ; forty-four species are recorded, and 
probably the number might be raised to 100. Very, little has 
been done in Lichens ; about 100 species are registered, and 
probably the number might be raised to 500, so that there is 
abundant work still to be done in this department. In Mr. 
W. B. Grove the county possesses a very competent resident 
mycologist. He has co-operated with Mr. Bagnall in the 
eighty pages of the book devoted to Fungi, and they 
very judiciously confine their list of stations to the Hymeno- 
mycetes and Gastromycetes. Then follows a tabular 
summary of the plants of the county, as traced through the 
ten drainage districts, and compared with the neighbouring 
shires of Leicester, Northampton, and Oxford. The book 
concludes with a very interesting sketch of the progress of 
botanical work in the county from the time of Ray down to
