Dr. Silva, in a personal communication, 
states that reef material of this plant collected 
by A. Conger and examined by him certainly 
belongs to the C. geppii complex, but is refer- 
able to C. bulbopilum Setchell, which he is 
about to decide to recognize in his mono- 
graph on Codium. 
Codium edule Silva, mentioned by Odum and 
Odum (1955/, has not been examined, but 
may be referable here.
