摘要

A new species from the Balsas river basin in Guerrero state, Mexico, is described and illustrated: Lepidagathis danielii (Acanthaceae). This new species is distinguished from all the known species of the genus because it has leaves and bracts with an apical spine, inflorescences with decussate flowers, a calyx with connate lobes of equal length, a red corolla that is 3 cm long and conspicuously bilabiate with a constriction near the base where the stamens are also inserted. In addition, the style is covered with scattered trichomes and the pollen is tricolporate without pseudocolpi.
