(5) That, consequently, the mosses not only represent the highest 

 development known of the cellular cryptogams, but the highest point 

 in one line of development, in which the oophytic generation took 

 the lead in importance ; whilst the vascular cryptogams and phane- 

 rogams are the results of another and more successful line of develop- 

 ment, in which the sporophytic generation took the lead as the 

 prominent part in the life-history. 



The appearance of similar organs in two independent lines of 

 development — i. e. of the leaves, stem, and epidermis — in the mosses, 

 and then in the ferns, without any relation of descent, is a thing well 

 worthy of being pondered over by those who study evolution : it may 

 suggest that the two lines of development, though independent, are 

 governed by some principle which brings about such like results : it 

 may be compared with the liknesses which occur in the animal 

 kingdom between the placental and marsupial mammals. 



The remaining columns of the table above given will best be 

 understood after a study of the next succeeding table. 



Modes of Mep'oduction. — Hitherto we have considered only the 

 reproduction from a spore produced in the special organ for their 

 production — the spore capsule. But, in fact, one of the most striking 

 peculiarities of the mosses is the vast variety of their modes of repro- 

 duction.
