In this article we will discuss about the morphology of psilotum with the help of a suitable diagram. Also learn about its phylogenetic position. Two species of Psilotum recognized are P. nudum and P. flaccidum (P. complanatum). Of these P. flaccidum is a pendulous epiphyte, rare in distribution; restricted to Jamaica, Mexico, Hawaii and a […]

In this article we will discuss about the life cycle of bryophytes with the help of diagrams. The life cycle of a bryophyte involves an alternation of generations—the gametophyte and sporophyte, which are different in morphology (heteromorphic) and differ in their level of ploidy (heteroploid). The gametophyte or gamete-producing generation is distinct in its morphology […]

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 […]
