Polyphyly of Mussaenda inferred from ITS and trnT-F data and its implication for generic limits in Mussaendeae (Rubiaceae).
Although recognition of Mussaenda as a separate genus has been widely accepted, its generic circumscriptions have always been controversial. In this first molecular phylogenetic study focusedExpand

Phylogeny of Sesuvioideae (Aizoaceae) - biogeography, leaf anatomy and the evolution of C4 photosynthesis
Abstract Sesuvioideae (Aizoaceae) form a small subfamily of drought-tolerant plants exhibiting leaf succulence, halophytic ecology, and the C4 photosynthetic pathway. Sesuvioideae are sister to theExpand
