BEITISH ISLES. 



"With Descriptions of all the Species, Varieties, and Hybrids. 



By ALFRED FRYER. Illustrated by ROBERT MORGAN", F.L.S. 



The object of this work is to supply a long-needed set of good and reliable Illus- 

 • rations of British Pot&mogetons. Both Descriptions and Illustrations will include 

 'he varying forms and states as well as the generally recognized species. The 

 synonymy, though not aiming at absolute completeness, will be ample for all 

 vorkiug purposes. An attempt will be made towards a natural arrangement of the 

 pecies founded on the changes of form in their progressive stages of growth rather 

 ban on the comparatively limited distinctions afforded by the fruit, illustrations of 

 vhich will form a special feature. 



The work will be issued in 15 monthly parts : prospectus on application.
