in this article we will discuss about the modes of reproduction in psilotum with the help of diagrams. Stout aerial branches bear large conspicuous sporangia (Fig. 7.1 A). Each sporangium is a 3-lobed structure (Fig. 7. 1B, C). It is borne on a forked appendage. It has been described as: (a) Trilocular sporangium (b) Trisporangiate […]
