Floral Morphology and Systematics of Lamourouxia (Scrophulariaceae: Rhinanthoideae). Smithsonian Contribuitons to Botany, Number 6

摘要

Relationships among the twenty-six species, having an overall range from northern Mexico to central Peru, are analyzed in regard to pollinators and for insight into the differentiation of the three taxonomic sections of the genus. Four new names are proposed, including a section, two species, and a combination. Two new chromosome numbers are reported. Descriptions for each of the species and a dichotomous key are included.
