Abstract:Premise
Staminodes are commonly studied in hermaphroditic flowers, in which a fraction of the androecium evolves into infertile structures, but few studies have addressed the evolution of staminodes as they occur through the loss of stamen function in carpellate flowers. Plants of Paronychia (Caryophyllaceae) are monoecious with hermaphroditic flowers with one staminodial whorl, except for the dioecious P. chartacea and P. minima. Dioecious species have carpellate flowers that evolved an additional whorl of st… Show more
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.
