J. M. Ricketson and J. J. Pipoly (1997) discussed the correct application of the name Myrsine cubana. The widely used name M. floridana A. de Candolle is superfluous.
Myrsine cubana has sometimes been confused with M. guyanensis (Aublet) Kuntze, a South American species found in Brazil, the Guianas, and eastern Venezuela; see J. J. Pipoly (1992, 1992b) for the diagnostic features separating these taxa. In addition, M. cubana has a confused nomenclatural history; see J. M. Ricketson and Pipoly (1997) for a discussion.
