Abstract

Rhipsalis rhombea is common in living collections, but the name has been used ambiguously in recent decades and has never been typified. We review the taxonomic history of this species and conclude that the name can be applied unambiguously. We therefore establish a neotype for Rhipsalis rhombea Pfeiff. and give a detailed morphological characterization of the species. In addition, we have generated plastid DNA sequences of the neotype which allowed us to establish the phylogenetic placement of R. rhombea within Rhipsalis subg. Phyllarthrorhipsalis.
