Abstracts
Ophioglossum is one of the three taxa of eusporangiate fern family Ophioglossaceae. It is distributed throughout the world. In India more than a dozen species are known. Studies on systematics, morphology, anatomy, reproduction biology, cytology, phytochemistry and phylogeny are reviewed in this paper. Ophioglossum includes four subgenera i.e. Cheiroglossa, Ophioderma, Euophioglossum, and Rhizoglossum. Steler system is either cauline or foliar in origin. Leaf traces single or double. Ontogeny and anatomy of the common stalk and tropophyll vary with species. Sclerenchyma is absent in ground tissue. Sporangia globose eusporangiate in two rows on lateral sides of the stalked spike.
