New molecular phylogenetic evidence for Indian endemic species of the tribe Merremieae, Convolvulaceae

Recent advances in molecular phylogenetics the family Convolvulaceae Juss. (particularly formerly recognized tribe Merremieae) have brought new insights on generic delimitation. Therefore, many species were transferred across genera to accommodate classification. However, additional morphological and analyses are still needed address affinities position of some included Merremia Dennst. ex Endl.s.l. allied genera. In this study, we provide a phylogenetic framework for placement Indian arrangement status doubtful distinct species. Distimake rhyncorhiza (Dalzell) A.R. Simões & Staples is proved its place Raf., while Operculina tansaensis Santapau Patel validated as from O. turpethum (L.) Silva Manso. A nomenclatural clarification misuse name “Merremia gangetica Cufod”. India provided, with an encouragement use correct emarginata (Burm.f.) Hallier f. The addition phylogeny suggests possible non-monophyly Camonea vitifolia Staples, albeit weakly supported. We provided descriptions, distribution maps notes nomenclature.
