Eustephieae is a flowering plant tribe in the family Amaryllidaceae, subfamily Amaryllidoideae. It forms part of the Andean clade, one of two clades in The Americas. [3]
Eustephieae are bulbous plants with often long-necked bulbs and linear leaves. [4]
The pedicellate, tubular flowers are borne on a solid scape. [4]
It was published by John Hutchinson in 1934 [2] with EustephiaCav. as the type genus. [5] [2]
This tribe was resurrected from the Stenomesseae in 1995, by Meerow. [6] The placement of Eustephieae within subfamily Amaryllidoideae is shown in the following cladogram, where this tribe is shown as a sister group to the remainder of the tetraploid Andean clade. [7]

The tribe has four genera:
The Eustephieae form the southern limit of the Andean clade. They are found in Peru in the southern Andes, and the northern Andes of Argentina, Bolivia and Chile. This is distinct from the central Andean distribution of the remainder of the parent clade. [7]
The Griffineae is a tribe in the family Amaryllidaceae, subfamily Amaryllidoideae. It includes 3 genera with 22 species endemic to Brazil in South America. A typical character of the representatives of the tribe are the flowers - They are blue or lilac and collected into an umbel. Only the members of this tribe and the genus Lycoris are able to form flowers with such color in the whole subfamily Amaryllidoideae of Amaryllidaceae. The species in this group are typically perennial and produce bulbs. The leaves are green, with elliptical form in most of the cases but in some members, as in Worsleya, they are sword-shaped.
Alan W. Meerow is an American botanist, born in New York City in 1952. He specializes in the taxonomy of the family Amaryllidaceae and the horticulture of palms and tropical ornamental plants. He also works on the population genetics and molecular systematics of cycads and palms.
The Amaryllidaceae are a family of herbaceous, mainly perennial and bulbous flowering plants in the monocot order Asparagales. The family takes its name from the genus Amaryllis and is commonly known as the amaryllis family. The leaves are usually linear, and the flowers are usually bisexual and symmetrical, arranged in umbels on the stem. The petals and sepals are undifferentiated as tepals, which may be fused at the base into a floral tube. Some also display a corona. Allyl sulfide compounds produce the characteristic odour of the onion subfamily (Allioideae).
Hippeastreae is a tribe of plants belonging to the subfamily Amaryllidoideae of the Amaryllis family (Amaryllidaceae). Species in this tribe are distributed in South America. Flowers are large and showy, zygomorphic, with the stamens in varying lengths, inflorescence bracts are often fused basally. The seeds are flattened, winged or D-shaped. Reported basic chromosome numbers are x= 8-13, 17, and higher. All the species in this tribe present a remarkable aesthetic interest and horticultural value.
Amaryllidoideae is a subfamily of monocot flowering plants in the family Amaryllidaceae, order Asparagales. The most recent APG classification, APG III, takes a broad view of the Amaryllidaceae, which then has three subfamilies, one of which is Amaryllidoideae, and the others are Allioideae and Agapanthoideae. The subfamily consists of about seventy genera, with over eight hundred species, and a worldwide distribution.
ZephyrantheaeSalisb. is a now obsolete tribe within the American clade of family Amaryllidaceae, containing five genera.
Narcisseae is a small tribe of plants belonging to the subfamily Amaryllidoideae of the Amaryllis family (Amaryllidaceae), where it forms part of the Eurasian clade, and is one of three tribes in the European (Mediterranean) clade. It contains two genera and approximately 58 species, but probably also Lapiedra. The two genera are distinguished from each other by the presence of a paraperigonium in the former.
Galantheae is a tribe of European, West Asian and North African flowering plants belonging to the subfamily Amaryllidoideae of the Amaryllis family (Amaryllidaceae). As of 2017, it contains three genera, although more were included previously. The position of the ovary is inferior.
Haemantheae are a tribe of subfamily Amaryllidoideae. They are herbaceous monocot perennial flowering plants with a predominantly African distribution. Three subtribes are proposed and six genera including the type genus, Haemanthus, are included. They are characterised by the presence of baccate (berry) fruit.
Calostemmateae are a very small tribe of subfamily Amaryllidoideae. They are herbaceous monocot perennial flowering plants endemic to Australasia. The tribe consists of two genera, Proiphys and Calostemma.
Lycorideae are a small tribe of subfamily Amaryllidoideae. They are herbaceous monocot perennial flowering plants endemic to Asia, and consisting of two genera including the type genus, Lycoris.
Pancratieae are a small European tribe of subfamily Amaryllidoideae, consisting of two genera including the type genus, Pancratium.
Traubiinae is a subtribe of plants classified under the tribe Hippeastreae. It belongs to the subfamily Amaryllidoideae of the Amaryllis family (Amaryllidaceae).
Stenomesseae was a tribe, where it forms part of the Andean clade, one of two American clades. The tribe was originally described by Traub in his monograph on the Amaryllidaceae in 1963, as Stenomessae based on the type genus Stenomesson. In 1995 it was recognised that Eustephieae was a distinct group separate from the other Stenomesseae. Subsequently, the Müller-Doblies' (1996) divided tribe Eustephieae into two subtribes, Stenomessinae and Eustephiinae.
Eucharideae is a tribe of plants within the family Amaryllidaceae. 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. Further revisions were made in 2020, when three genera were merged. It forms one of the tribes of the Andean subclade of the American clade of the subfamily.
Clinantheae is a tribe, where it forms part of the Andean clade, one of two American clades. The tribe was described in 2000 by Alan Meerow et al. as a result of a molecular phylogenetic study of the American Amaryllidoideae. This demonstrated that the tribe Stenomesseae, including the type genus Stenomesson was polyphyletic. Part of the tribe segregated with the Eucharideae and were submerged into it, while the other part formed a unique subclade. Since the type species of Stenomesson was not part of the second subclade, it was necessary to form a new name for the remaining species together with the other genera that remained. This was Clinanthus, the oldest name for these species, and consequently the tribe Clinantheae.
Hymenocallideae is a tribe, where it forms part of the Andean clade, one of two American clades. The tribe was originally recognised by both Meerow (1995) and the Muller-Doblies' (1996). Its phylogenetic position within the Amaryllidoideae was established by Meerow et al. in 2000, while in-depth infratribal relationships were established in 2002.
Cliviinae is a small subtribe of Haemantheae, and therefore within the African clades of Amaryllidoideae. It consists of two genera, Clivia, and Cryptostephanus.
Gethyllidinae is a small subtribe within the amaryllis family. It is within tribe Haemantheae, and therefore within the African clades of Amaryllidoideae. It contains two genera, Gethyllis and Apodolirion, both are endemic to southern Africa.
Amarylloidinae is a now obsolete informal name for an "infrafamily" within the Amaryllidaceae (Amaryllis) family, erected by Hamilton Traub. This grouping was designed to fill a perceived gap between the formal rank of subfamily and tribes. In his treatment of this family, he divided it first into four subfamilies. Within subfamily Amarylloideae he then divided his sixteen tribes into two infrafamilies, Amarylloidinae and Pancratioidinae, both of which were subsequently demonstrated to be polyphyletic, and hence were abandoned by Dahlgren, who used no rank between family and tribe. On the other hand, he also used a much more restricted Amaryllidaceae corresponding to Traub's subfamily Amarylloideae. Thus Traub's Amarylloideae most closely resembles subfamily Amaryllidoideae sensu APGIII.
