Mitreola petiolata (Loganiaceae): one global species or several cryptic lineages?

Mitreola petiolata (J.F. Gmel) Torrey & A. Gray (Loganiaceae) is a widespread annual herb in the southeastern United States, the Caribbean, Latin America, southeast Asia, southern Africa, and northern Australia. Based on inflorescence structure and fruit shape, there are three apparently distinct forms in the New World. The type specimen is from South Carolina and corresponds to the North American form which is also found in the Caribbean and in Belize, with the other two forms appearing to be sympatric throughout Central America and South America. The relationship between these forms and plants in the Old World is unclear. Does this taxon represent a single widespread polymorphic entity, as currently treated, or might there be three or more cryptic lineages "hiding" within this name?
