This study contributes to our knowledge of the flora from high Andes of Bolivia by the description and characterization of five new, high-altitude species of Gentianaceae: Gentianella campaniflora, G. potosiana, G. pringlei, G. puberula, and G. samae. The new species are compared with similar species in their morphology, ecology, phenology and distribution. Line drawings and photographs serve to illustrate the species. [ABSTRACT FROM AUTHOR]
