THE HEP ATICJE 
OF 
THE BRITISH ISLES, 
By W. H. PEARSON. 
1 The descriptions of the species are clear and full, and the shorter notes which accompany 
many of them are interesting and often of critical value. . . . The geographical distribution of each 
species is mentioned, and frequently the actual localities also. ... A glossary, table of literature, 
and a good index complete the volume. . . . The 228 plates form a splendid adjunct to the text, 
and will prove of material service in the proper identification of the various species ; each generally 
includes a life-size representation of the species, as well as drawings on a large scale of dissections, 
fructifications, & c. The cellular structure of the leaves is also depicted, and this will often be 
found of much value in deciding between doubtful cases. . . . Mr. Pearson has laid British botanists 
under great obligations, and has succeeded in producing a book that ought to serve to rescue from 
comparative, though altogether unmerited, oblivion a family by no means the least interesting of 
the vegetable kingdom.’ — Nature.
