Ferns play an important role in the evolutionary studies with their unique phytochemicals and eccentric stellar regions. According to PPG, Polypodiales include maximum macro-ferns and this study focused on the anatomical and phytochemical properties of two aquatic sister Salviniaceae ferns, Azolla filiculoides and Salvinia molesta. The histological studies using safranin stain, GC-MS using the methanol solution and antimicrobial test by induction disk diffusion- agar method was used for the study. The hadrocentric anatomy, aquatic adaptations of Azolla filiculoides and Salvinia moelsta were studied. The methanolic extract (ME) of these ferns showed Cyclohexasiloxan in large quantity, that has antibacterial and antiproliferative activity and ME of Azolla shows more antimicrobial activity than Salvinia. Also, the phytochemical contents are also high in Azolla sp than Salvinia sp. Anatomical and Antimicrobial comparison of sister ferns in Salviniaceae using methanol shows Cyclohexasiloxan in a notable sum and the ecological and phytochemical adaptations of Azolla filiculoides is comparatively advanced than Salvinia molesta.

Azolla filiculoides, Salvinia molesta, antibacterial, stellar evolution, Cyclo-hexasiloxan.
