We find similar relationshipsamongst the Musci in the antheridia of Buxbaumia (Fig. 105), where theyare enclosed in an envelope like a mussel-shell and superficially resemble theantheridia of Hepaticae. The configuration of the body of the antheridiumis connected also with the distribution of the spermatozoids. The deeplysunk antheridia of the series of the Marchantiaceae and those of INIonocleaare club-shaped, whilst they have a more spherical form when they occupya more exposed positio
