Taxonomy
The American genus Helonias is morphologically close to two Asian genera - Heloniopsis and Ypsilandra . Previously, these three genera were sometimes combined into one, but according to the results of molecular phylogenetic studies, they were recognized as quite clearly limited from each other and combined into the tribe Heloniadeae .
