A profound study in the morphology of the lowest forms of plants, with 

 special reference to the development of their reproductive systems. The 

 author endeavors to show that the present land flora has originated from an 

 aquatic ancestor, and traces the methods of specialization to the land habit, 

 and the establishment of the forms of the higher plants. A book of the 

 highest importance not only to botanists but to biologists in general.
