Eucharideae

In Traub's 1963 monograph on the Amaryllidaceae, he conceived of a tribe Euchareae based on the type genus, Eucharis and constituted from six genera in total.{{sfn|Traub|1963}} In 1996, 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.{{sfn|Müller-Doblies|Müller-Doblies|1996}} In 1998, Meerow and Snijman considered these separate tribes, retaining only four genera in their Eucharideae.{{sfn|Meerow|Snijman|1998}} In 2000, the tribe was then considerably reconstituted following a deconstruction of tribe Stenomesseae based on molecular phylogenetics, resulting in seven genera (Plagiolirion was not included). However, relationships were not fully resolved.{{sfn|Meerow et al.|2000b}}

The placement of Eucharideae within subfamily Amaryllidoideae is shown in the following cladogram:{{sfn|Meerow et al.|2000b}}

A 2020 molecular phylogenetic study showed that genera accepted in 2000 required further revision. A summary cladogram from the study combined Eucharis, Caliphruria and Urceolina in a single clade, as well as showing that two species were wrongly placed.{{sfn|Meerow|Gardner|Nakamura|2020}}
