What is "clusiella"

Clusiella is a plant genus of the family Calophyllaceae. When Planchon and Triana first published it in 1860, based on Clusiella elegans, the genus was considered monotypic and remained as such for about 100 years.

This genus is confined to the Neotropics, occurring in Costa Rica, Panama, Colombia, Venezuela, Ecuador, northern Peru, and northern Brazil.
