Angelonia

About

Angelonia is a genus of flowering plants in the family Plantaginaceae. It comprises about 30 species which occur from Mexico to Argentina. Species of the genus Angelonia are herbaceous plants occurring mainly in arid and semi-arid habitats. Most species can be found in north-eastern Brazil in the seasonally-dry tropical forest Caatinga. The flowers of Angelonia species are highly specialized for pollination because they have hairs in the inner corolla, which produces oils collected by oil bee pollinators, especially of the genus Centris.
