New combinations in Dendrobium (Orchidaceae)

Abstract

Molecular phylogenetics of Subtribe Dendrobiinae (Orchidaceae -Epidendroideae) have revealed that Cadetia, Diplocaulobium, Flickingeria and Grastidium are nested within Dendrobium as traditionally circumscribed. We consider that there are compelling reasons, based on evidence and the desirability of nomenclatural stability, to recombine these genera as well as Euphlebium and Epigeneium (among others) within Dendrobium. New combinations are presented where species do not presently have valid Dendrobium names.
