Anaphyllopsis is a genus of flowering plants in the family Araceae, native to northern South America. The genus was created in 1988 by Hay in order to account for the differences of Cyrtosperma americanum from other Cyrtosperma species. The decision was to create a genus named Anaphyllopsis and rename Cyrtosperma americanum as Anaphyllopsis americanum.
