Taxonomy
The genus ''Triaenophora'' was first erected by Hans Solereder
Hans Solereder (11 September 1860 Munich – 8 November 1920 Erlangen), was a German botanist and university professor.
Solereder studied biology from 1880 at the University of Munich, under Radlkofer, and was awarded a PhD in 1885. Fro ...
in 1909,[ based on a section of the genus '' Rehmannia'' which Joseph Dalton Hooker had called "''Trianophora''" in 1891.][ It was initially placed in the family Scrophulariaceae.][ When that family was shown by ]molecular phylogenetic
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to ...

In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic gro ...

A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, ...

In geometry, the circumscribed circle or circumcircle of a polygon is a circle that passes through all the vertices of the polygon. The center of this circle is called the circumcenter and its radius is called the circumradius.
