Pinguicula chuquisacensis (Lentibulariaceae), a new species from the Bolivian Andes, and first insights on phylogenetic relationships among South American Pinguicula

Abstract

Pinguicula chuquisacensis is described and illustrated as a new species from the department of Chuquisaca of Bolivia. Data on distribution, ecology and a key for identification among other central Andean species are given. DNA sequence data are presented for this new taxon and related Andean species of Pinguicula for the first time. The plastid tree reveals a lineage of central Andean species (within the clade of tropical growth type species), whereas the northern Andean (Colombia, Vene- zuela) P. elongata appears distantly related and sister to all remaining taxa of the Mexican-Central American-Caribbean clade of Pinguicula.
