 Note. — 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 methois of specialization to the land habit,

 botanists but to biologists in general.
