, '' Eucharis'' and constituted from six genera in total. However, the Müller-Doblies' deemed this to be polyphyletic, and redistributed the genera over three separate tribes, retaining Eucharideae as one of those tribes, but divided into two subtribes, Eucharidinae and Hymenocallidinae with a total of seven genera. Meerow and Snijman (1998) considered these separate tribes, retaining only four genera in their Eucharideae. The tribe was then considerably reconstituted following a deconstruction of tribe Stenomesseae based on molecular phylogenetics, resulting in seven genera.
