Adiantum caudatum Linn. is an important medicinal fern belonging to the family Adiantaceace, coming under Pteridophytes. It is used traditionally in folklore as ethno medicine to treat various diseases like cough, cold, throat infection, skin disease and diabetes. The in vitro life cycle of A.caudatum L. starting from spore germination, gametophyte formation, followed by micro morphological study and reproductionwas thoroughly studied in knop’s (Kn) and Knudson’s medium (Kc).Vittaria type of germination and Drynaria type of gametophytes evidenced on two media studied during the culture period. Presexual gametophyte, sex organ formation, fertilization, embryo development and sprouting of young sporeling were successful in Kc medium under in-vitro conditions. Experimental trials for spore germination percentage, gametophytic growth area and micromorphological differences between Kc and Kn medium studied were observed and interpreted. Bisexual potential, selfing potential and genetic load revealing reproductive potential was found out for the experimental plant studied and discussed. The optimum repeatable protocol for the micropropagation of this lithophytic medicinal fern was attained after 150 days of culture.
