Abstract

A new Rondeletia species (Rondeletieae, Rubiaceae) was collected by the combined German- Cuban research group of the National Botanical Garden of Cuba in the dry southern region of the historical province Oriente, actually Prov. Guantánamo, in the valley of Rio Seco between Imias and Cajobabo. The region is rich in small leaved sclerophyllous species belonging to the section Hypoleucae Fernandez-Zequeira, like R. acuminata, R. baracoensis, R. ingrata. It is also closely related to R. rugelii of the province Matanzas, and to the R. fuertesii of Hispaniola. From these mentioned species the new taxon differs in having naked corolla tube, a character completely unique in the section.
