E have now come to the Red " Sea Mosses." 

 They are more highly organized than the 

 plants we have been considering. This is apparent in 

 the greater variety of form, and complexity of structure, 

 as well as in the higher and more elaborate machinery 

 for the reproduction process, which is seen in them. 



The Red "Sea Mosses" are characterized by the 

 presence of two different kinds of seeds, or spores. 

 One kind is produced by a process analogous to that 

 by which seeds and fruit are produced in the flowering 

 plants ; that is, by the presence and co-operation 

 of a staminate and pistilate element. This is the
