 It was observed that the foot still persists on young plants -which show 

 as many as six to eight full-sized leaves. There was no trace of any 

 swelling on the young plant which could be interpreted as the rudiment 

 of a protocorm. The first root is developed relatively late. In the plants

 leaves had been formed. All roots in the young plant subsequent to- 

 the first root are adventitious, and make their appearance on the stem 

 above the foot (fig. 12).

In two previous papers (11, pp. 357-61, and 12) the writer has

 in its development will here be given in reference to several micro- 

 photographs and drawings which are included in this paper. The 

 prothallus of this species has already been described as belonging 

 to the L. cernuum type. During the early stages in its develop-
