Nautilocalyx melittifolius is a species of plant in the Gesneriaceae family. It is endemic to Grenada, where it grows to 30 cm in height, with leaves 1-8cm long and flowers reddish-pink or purple. Endemism is the ecological state of being unique to a defined geographic location, such as an island, nation or other defined zone, or habitat type; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, all species of lemur are endemic to the island of Madagascar; none are native elsewhere. The extreme opposite of endemism is cosmopolitan distribution.
