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.
