Salvinia) or less (e. G. Selaginella) through the ruptured outer coat of the macrospore.
Generally speaking, the symmetry of the prothallium is dorsi- ventral ; in the free-growing forms, the under surface generally bears numerous unicellular root-hairs. In some cases the pro- thallium shows more or less well-marked differentiation into a vegetative portion and a gametophore which may bear either both kinds of sexual organs, or, more commonly, one kind only ; when the gametophore bears only mal...e organs it is distinguished as an untheridiophore ; when only female organs, as an arche^joniopliore. The distribution of the sexual organs on the prothallium varies; they are frequently confined to one surface, but are occasionally scattered over the whole surface. The number of the sexual organs on a prothallium is in some cases only one, in others it is considerable.
The sexual organs are antheridia (male) and archegonia (female). The structure of the antheridium is simple ; it consists of a wall, a single layer of cells, enclosing the mother-cells of the spermato- zoids.
