Stenomesseae was a
tribe (in the family
Amaryllidaceae, subfamily
Amaryllidoideae), where it forms part of the Andean
clade, one of two American clades.[1] The tribe was originally described by
Traub in his monograph on the Amaryllidaceae in 1963, as Stenomessae based on the type genus Stenomesson.[2] In 1995 it was recognised that Eustephieae was a distinct group separate from the other Stenomesseae.[3] Subsequently, the Müller-Doblies' (1996) divided tribe Eustephieae into two subtribes, Stenomessinae and Eustephiinae.[4]
The advent of
molecular phylogenetics showed that the Stemomesseae (including Stenomesson) was
polyphyletic. Consequently, a separate tribe (
Clinantheae) was created from one group and the remainder, which
segregated with
Eucharideae was treated as another tribe. Initially it was suggested that this combined tribe be referred to as a newly circumscribed Stenomesseae,[5] but subsequently the term Eucharideae has been conserved.[6]
