Contribution to the phytosociological characteristics of the Yaguaramas savanna (Cienfuegos Province, Cuba)

The contribution presents phytosociological analyses of the savanna vegetation of Yaguaramas belonging to the classCuratello-Byrsonimetea Borhidi 1979. According to the plant composition, the plant communities under study belong to the orderByrsonimo crassifoliae-Andropogonetalia teneris Bal.-Tul. ordo nov., where two alliances were distinguished, namely theGuillemineo brittonii-Aristidion refractae Bal.-Tul. all. nov. and theByrsonimo crassifoliae-Andropogonion teneris Bal.-Tul. all. nov. The associationsSclerio interruptae-Rhynchosporetum subimberbis Bal. Tul. ass. nov., andPolygalo omissae-Andropogonetum diodontis Bal.-Tul. ass. nov. (both endemic) were classified in the former alliance while the associationByrsonimo crassifoliae-Andropogonetum teneris Bal.-Tul. ass. nov. is a representative of the latter. The following subassociations were distinguished: theSclerio interruptae-Rhynchosporetum subimberbis utricularietosum fimbriatae Bal.-Tul. subass. nov., theByrsonimo crassifoliae-Andropogonetum teneris typicum Bal.-Tul. subass. nov., and theByrsonimo-Andropogonetum sclerietosum interruptae Bal.-Tul. subass. nov.
