Resumen:
Deprea  (Solanaceae) is a small South American genus of 10 species occurring in Andean areas from Venezuela to Bolivia. The circumscription of Deprea  has been repeatedly modified in recent years, with new species being described and others transferred into or out of the genus. The relationships of  Deprea to other genera of Solanaceae are still poorly understood, although it seems to be closely related to  Larnax . A phylogenetic analysis was performed to test the monophyly of  Deprea. Sequences from three molecular markers (nuclear ITS and waxy and chloroplast  psbA-trnH) were analyzed by parsimony and Bayesian methods. All the species of  Deprea  and  Larnax sampled were intermixed in a strongly supported clade in the consensus  trees,  and  therefore  the  currently  recognized  Deprea   species  do  not  form  a monophyletic  group. At  least  four strongly supported clades could be recovered within the Deprea +  Larnax  assemblage, but the affinities of several species of both genera remained unresolved. Additional sampling including the majority of the Deprea +  Larnax  species and more representatives of genera in the Physalideae should be done to clarify relationships within the clade and to pinpoint the closest relatives of Deprea +  Larnax.
