and Leptadenia were studied for its taxonomic and phylogenetic significance. Epicarp is single layered in Calotropis, Ceropegia and Leptadenia, while in Marsdenia, Wattakaka, Tylophora and Gymnema it is multilayered. Mesocarp is parenchymatous possessing aerenchymatous tissue in all the genera studied. Endocarp is multilayered and lignified. Dehiscence of the follicle is marginicidal. Factors responsible for dehiscence are also discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
