Here we describe a new species of Pisonia (Caryophyllales: Nyctaginaceae) from Jamaica, named P. jamaicensis Proctor ex Caraballo, K.Campbell, & S.Cross, restricted to limestone hills in the central and western part of the island. The species description is complemented with an illustration, pictures, a distribution map, and notes on its biology and conservation, including an IUCN evaluation. We also present a list of the 27 currently accepted species of Pisonia with their general distributions, and a key to separate the 16 taxa reported for the West Indies.
