FLORA OF LIVERPOOL. AS 
The Flora of Liverpool. By JosrrH Dickinson, M.A., M.D.,

losophical Society, ete. 
A local flora is always welcome to the students of British 
plants, and will be duly noticed in the pages of the ‘Phytologist.’ 
The author in a note informs his readers “that this treatise is 
founded on the basis of ‘Hall’s Flora, and reprinted from the 
proceedings of the Liverpool Literary and Philosophical So- 
ciety.” 
There is prefixed to the work a brief account of the physical, 
geographical, and atmospherical conditions of the district to which 
this Flora is confined. 
The lat. is 53° 23’ N., long. 2° 54’ W. The country is flat, 
with slight undulations. 
The prevalent strata are the new red sandstone, consisting of 
friable sand, marl, clay, sandstone, micaceous slaty clay and 
quartzose sandstone, all in regular strata. The mean annual 
fall of rain is stated to be 28°05 inches, and the mean annual 
temperature 49°9° Fahr. The area embraced in the work is fifteen 
miles from Liverpool on all sides, except where it is bounded by 
the sea. We have made a rough calculation of the number of 
species entered in the Flora, and we subjoin the result :— 
Pheenogamous plants, 780 species. Dicotyledonous plants, 600 species. 
Filices and their allies, 32 Mt Monocotyledonous ditto, 180° ,, 
We believe that the ‘Flora of Godalming,’ in Surrey, as collected 
and prepared for the Botanical Society of London by Mr. Sal- 
mon, contains nearly as many plants (species) as the ‘ilora of 
Liverpool.’ The area of the Godalming district is about 50 square 
miles, 4 miles from Godalming, or a circle having a diameter of 8 
miles and a radius of 4. The area of the semicircular tract embraced 
by the ‘Liverpool Flora,’ with its diameter of 30 miles and radius 
of 15, after deducting the western side of the circle, cannot be 
much less than 350 square miles, or about seven times the area of 
the Godalming tract as limited above. We may also take into 
the account that although one-half of the circular tract is covered 
by the sea, yet the deficiency of vegetation arising from this cause 
is partly supplied by the presence of maritime plants, which of 
course do not occur in Surrey. Hence it is to be inferred that 
geological relations have considerable influence on the distribu-
