A has the " succubous," B the " incubous "disposition of the leaves. (After Cavers.) of the gametophyte in Liverworts. Its results offer analogies with the special adaptations seen in the sporophyte of Flowering Plants. The sexual organs are essentially similar to those of the Mosses; but there are differences in their segmentation. This suggests that their origin may have been distinct. In the thalloid Liverworts they are always borne on the morphologically upper surface ; but by various means they are carefully protected, being sometimes sunk deeply in the thallus (Fig. 311). In the Jungermanniae they are covered in by envelopes, the number and variety of which give useful features in classification. A particular interest attaches to those which develop a " marsupium," that is a nursing-sac surrounding the archegonia,.
