''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). It forms one of the tribes of the Andean subclade of the American
clade of the subfamily.
Taxonomy
In
Traub's monograph on the Amaryllidaceae (1963), he conceived of a tribe Euchareae based on the
type genus
In biological taxonomy, the type genus is the genus which defines a biological family and the root of the family name.

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.
Phylogeny
The placement of Eucharideae within subfamily Amaryllidoideae is shown in the following cladogram:
