Die Verschiedenheit der Floren der einzelnen Gebirge in der Pro- 
vinz ÖOriente hebt Exmav in einem Briefe von 1921 hervor: „The 
mountains of Cuba have all floras of their own, even if separated by 
narrow strips of lowland. So is Sierra de Nipe very different from 
Sierra Cristal and these from the Baracoa-mountains. Sierra Maestra 
is again very unlike those mountains.*
