It was augmented in 2000 by Meerow et al. following a molecular phylogenetic study that revealed that many elements of the tribe Stenomesseae segregated with it, rather than separately, and were subsequently submerged in it (although there was an initial proposal to rename this clade Stenomesseae).

[4] 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.

[6] In 1998, Meerow and Snijman considered these separate tribes, retaining only four genera in their Eucharideae.

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.
