Angelonia is a genus of about 30 species which occur from Mexico to Argentina and is classified in the Plantaginaceae. They are herbaceous plants occurring mainly in arid and semi-arid habitats. Most Angelonia species can be found in Northeastern Brazil in the seasonally-dry tropical forest namely Caatinga.{{cite journal|last1=Martins|first1=Aline C.|last2=Alves-dos-Santos|first2=I.|title=Floral-oil-producing Plantaginaceae species: geographical distribution, pollinator rewards and interactions with oil-collecting bees|journal=Biota Neotropica|date=2013 |volume=13|issue=4|page=77|doi=10.1590/S1676-06032013000400008 |url=http://www.biotaneotropica.org.br/v13n4/en/abstract?article+bn01313042013}} The flowers of Angelonia 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.{{cite journal|last1=Martins|first1=Aline C.|last2=Aguiar|first2=Antonio J.
