The genus Schaueria (Acanthaceae) has not been comprehensively treated for more than 150 years. Here, we propose a recircumscription of Schaueria based on molecular phylogenetic results and present a taxonomic revision of the genus. We recognise 14 species, which occur mainly in semideciduous montane forests, rain forests, and restingas, from Bahia to Rio Grande do Sul states, Brazil. Three new species are described in the genus—S. hirta, S. pyramidalis, and S. thyrsiflora—and six are excluded… 

Two new genera of Acanthaceae from tropical Africa

DNA sequence data, macro-morphological evidence and pollen analysis are used to clarify the phylogenetic placement of two African species of Acanthaceae: Schaueria populifolia C.B.Clarke and



Revision of Stenostephanus (Acanthaceae) in Mexico

The Tetramerium lineage (Acanthaceae: Justicieae) does not support the Pleistocene Arc hypothesis for South American seasonally dry forests.

The congruence among biogeographical events found for the Tetramerium lineage suggests that the dry forest centers currently dispersed throughout South America are relatively old remnants, probably isolated since the Neogene, much earlier than the Last Glacial Maximum postulated by the Pleistocene Arc hypothesis.

The “Tetramerium Lineage” (Acanthaceae: Acanthoideae: Justicieae): Delimitation and Intra-lineage Relationships Based on cp and nrlTS Sequence Data

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.
