Abstract

Many new combinations are needed in Euploca, previously regarded as Heliotropium section Orthostachys, to correspond with results of our forthcoming, world-wide, molecular phylogenetic analysis. We also need these names for our many δ13C determinations that identify many Euploca species exhibiting C4 photosynthesis and show that other Euploca species are not C4. Here we make the many new combinations required to support these results.
