Taxonomy

Phylogeny

This tribe was resurrected from the Stenomesseae in 1995, by Meerow. 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.

Subdivision

The tribe has four genera:

• Eustephia
• Chlidanthus
• Hieronymiella
• Pyrolirion

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.
