How did phylogenetic studies change the classification of Saccifolium bandeirae?

The classification of Saccifolium bandeirae was revised following phylogenetic research that clarified its evolutionary position. Previously, the plant was placed in its own distinct family, Saccifoliaceae, primarily due to its unique, pouchlike leaves—a morphological feature not observed in any other plant species.1

However, modern phylogenetic studies have demonstrated that despite this unusual appearance, Saccifolium bandeirae is actually a member of the Gentianaceae family. Specifically, these genetic analyses place the species within the most basal tribe of the Gentianaceae family tree.1
