Many investigators have been engaged upon the examina- 

 tion of this plant; I mention below the chief authors and their 

 papers. 



BERTHOLD 1 ) in his useful treatise has given some short notes 

 on this alga, but DEBRAY 2 ) and BIGELOW S ) were the first to 

 give a more detailed description of the structure of it. Their 

 papers were worked out quite independently of each other at 

 about the same time. A few years later, in 1890, DEBRAY pub- 

 lished a "2me Memoire", Sur la structure et le developpement 

 des Chylocladia, Champia et Lomentaria 4 ) in which he ampli- 

 fies his former paper. Later on DAvis 5 ) has given a detailed 

 description of the development of the frond of Champia 

 from the carpospore, and in the same year HAUPTFLEiscH 6 ) 

 gives, besides a short description of the vegetative structure of
