Task: Explanation
Input (English): Gesneria is a genus of approximately 50 species in the flowering plant family Gesneriaceae. Except for two or three odd South American species, all are native to islands of the Caribbean. The genus is classified in the tribe Gesnerieae along with the genera "Bellonia", "Pheidonocarpa", and "Rhytidophyllum". "Gesneria" species are usually woody shrubs or subshrubs, and (with the closely related "Rhytidophyllum") are unusual in the family in having alternately (rather than decussately) arranged leaves. A complete list of the accepted species and their synonyms can be found in the Smithsonian Institution's World Checklist of Gesneriaceae. Question: Which is native to the Caribbean, Myrteola or Gesneria? Answer: Gesneria
Output (English):  Except for two or three odd South American species, all are native to islands of the Caribbean.
