Periderm in Ophioglossaceae

Sharda Khandelwal, H. K. Goswami

Abstract


This paper describes the occurrence of periderm in three genera, Botrychium Swartz., Helminthostachys Kaulfuss, and Ophioglossum Linn. under field conditions. Not all plants of an area belonging to the same or different species possess it. Based on population survey it is suggested that production of functional cork cambium (phellogen), a feature unlike Fillicenae may be an inherited trait.
