Morphological and ontogenetic studies with inflorescences and flowers of Lepidagathis Willd. (Acanthaceae)

The phylogeny of Acanthaceae, chiefly based on molecular data, confirms the monophyly of the family, however, a morphological synapomorphy to characterize it is still unknown. Apart from being well represented in our flora, the identification of its species is quite difficult due to taxonomic problems and lack of morphological studies.
