Note: this taxon list is still under construction. It does not yet contain all known Ruellia harveyana clade subgroups.

Containing group: Ruellia s. l.


Phylogenetic analyses from Tripp (in press) revealed a small, moderately supported lineage, the Ruellia harveyana clade, that contains four species. There are surely other species that belong to this group, but these were not included in taxon sampling for the study. There are no known synapormorphies to unite these species. Ruellia nobilis, a rare and endemic species of the Chaco in S. South America, has very long, white corolla tubes–the narrow, unexpanded portion of the tube is approximately 10 cm long. Other species in this group have purple flowers and occur in S. South America, Central America, and Mexico.

This page is a Tree of Life Branch Page.

Each ToL branch page provides a synopsis of the characteristics of a group of organisms representing a branch of the Tree of Life. The major distinction between a branch and a leaf of the Tree of Life is that each branch can be further subdivided into descendent branches, that is, subgroups representing distinct genetic lineages.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
