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]

Description

Vegetative characteristics

Eustephieae are bulbous plants with often long-necked bulbs and linear leaves.^[4]

Generative characteristics

The pedicellate, tubular flowers are borne on a solid scape.^[4]

Taxonomy

It was published by John Hutchinson in 1934^[2] with Eustephia Cav. as the type genus.^[5]^[2]

Phylogeny

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]

Subdivision

The tribe has four genera:

Eustephia Cav.^[4]
Chlidanthus Herb.^[4]
Hieronymiella Pax^[4]
Pyrolirion Herb.

Distribution

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]
