(Continued from 2). 196.)

 in the same enveloping leaves, as in Mnium suhglobosuvi ; monoicous 

 when these organs occur in different buds on the same plant, as in 

 Hypnum rutabulum ; dioicous when the male organs occur on one plant 

 and the female on another plant of the same species, as in Ceratodon 

 ptirpureus.
