[1] The tribe was originally described by Traub in his monograph on the Amaryllidaceae in 1963, as Stenomessae based on the type genus Stenomesson.
[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.
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] The placement of Stenomesseae, now Eucharideae within subfamily Amaryllidoideae is shown in the following cladogram.
