In reading the available scientific literature on these species, the description focuses on separating them from Sabal causiarum. However, given the great geographical distance between Puerto Rico and Bonaire, and the fact that Sabal is not present in the Lesser Antilles, it would seem logical to think that these recently described species are more closely related to Sabal mauritiiformis, which is present in nearby South America. Does anyone know more about this?

Do you have this paper?  I think this is the latest publication about the genetics for these two species, but I am not sure that it resolves their relationships to other Sabal definitively.
