Abstract

Molecular studies carried out by Achille et al. (2006), revealed the polyphyly within the big genus Guettarda and in its relationships, among others the polyphyletic character of the genus Stenostomum C. F. Gaertn. studied earlier by Borhidi and Fernandez (1995 a , b ) based on morphological characters. This fact stimulated a re-examination of the traditional Stenostomum genus, which concluded in the separation of the section Resinanthus Borhidi at generic level and its new generic circumscription. The genus is divided into two sections. Sectio Resinanthus contains 15 species of the West Indies, mainly of Cuba and Hispaniola, and the sectio Macresinanthus sect. nov. has one Mexican species.
