HISTOLOGY OF A XEROPHYTIC LEAFLET: CYCAS CIRCINALIS AND CYCAS REVOLUTA (CYCADACEAE)

Abstract

Cycas, a primitive gymnosperm is currently facing extinction since the stem produces a starch like substance called sago, also called as sago palm. Cycads are xerophytic as they require scanty water even more drought tolerant. This study compares the leaflet micromorphological characters as a taxonomic tool to independently identify two Indian Cycad species. Cycas.circinalis and Cycas.revoluta. Anatomical investigations were carried out and presented. Phytochemicals and physicochemical analysis of powdered leaflet was also carried out.
