Aeschynanthus is a genus of about 150 species of evergreen subtropical plants in the family Gesneriaceae. They are usually trailing epiphytes with brightly colored flowers that are pollinated by sunbirds. The genus name comes from a contraction of aischuno (to be ashamed) and anthos (flower). The common name for some species is "lipstick plant", which comes from the appearance of the developing buds. A full list of the accepted species and their synonyms can be found in the Smithsonian Institution's World Checklist of Gesneriaceae.
