TL;DR: This study sampled all known lineages of Acanthaceae including Andrographideae and used sequence data from nrITS and four chloroplast noncoding regions, and parsimony and Bayesian methods of analysis to strongly support most aspects of relationships.

TL;DR: Results of parsimony and Bayesian analyses provided strong support for monophyly of two sub-lineages of Acantheae, referred to here as the ‘one-lipped corolla’ and ‘two-lipping corolla' lineages, reflecting notable differences in corolla morphology.

TL;DR: A solid phylogenetic hypothesis of relationships within Ruellieae contributes to progress in biology in three important ways: it enables better assessment of trait homologies and thus characters upon which genera are delimited, it contributes to the Global Strategy for Plant Conservation’s initiative to document plant biodiversity, and it facilitates cross-family comparative evolutionary analyses.

TL;DR: It is proposed that sternotribic flowers as synapomorphic for the core Tetramerium lineage, and flowers with the lower-central lobe of the corolla modified into a keel as a synapomorphy for a lineage consisting of Tet Kramerium and the core Carlowrightia clade, are proposed.
