The development of both gametophyte and sporo-phyte in the two corresponds very closely. The sporangia are borne in sporocarps, which are morpho-logically very different from those of the Salviniaceae, beingmetamorphosed leaf segments enclosing several sori, and notsingle sori enclosed simply in an indusium. The sporesgerminate with extraordinary rapidity, especially in Marsilia, XII LEPTOSPORANGIA T.E HETEROSPORErE 399 and in M. JEgyptiaca the writer has found a two-cel
