dioicous ; more recent work has tended toward the conclusion that for the 

 most part it is monoicous. Miss Brown made an immense number of single 

 spore cultures in pots, and studied the behavior in the formation of sex 

 organs. Some of the cultures ran for two years. She concludes that 

 Funaria hygrometrica is strictly monoicous, but with considerable variation in 

 the position of the sex organs. Usually the antheridia appear first, and at 

 the apex of the main axis, while the archegonia develop later at the ends of 

 branches. In some cases the gametophore is unbranched and produces 

 either antheridia or archegonia ; when branches are formed they may bear 

 either kind of sex organs. But in every case the spores, protonemata, and 

 gametophores are bisexual in their potentialities.
