Abstract Phacelia sect. Glandulosae , with ca. 62 taxa, is the most diverse of 11 sections genus (Hydrophyllaceae). The family largely restricted to North and Central America, but has an amphitropical distribution nine species reported from western South five which have been assigned P . These are found in arid semi‐arid Andean habitats between 1000 5000 m a.s.l. Species delimitation long confounded for this plant group America by some degree taxonomic chaos – lack typifications, dozens synonyms, different names used same taxon countries poor representation molecular phylogenies. Here, we try improve our understanding employing a ddRADseq strategy investigate phylogenetic relationships all American representatives based on total 33 sampled specimens. Both maximum likelihood tree inference analyses data resulted well‐resolved topology. All currently recognized form highly supported monophylum including P. nana previously considered as belonging Euglypta However, morphospecies clade very short branch lengths indicating coalescence processes at level population, except artemisioides clearly sister rest. Additionally, ecotypes retrieved poly‐ and/or paraphyletic. Based these results re‐evaluation morphological characters traditionally delineate within argue that limited diagnostic value. We recommend recognizing only two section: polymorphic pinnatifida its closely related A revised formal taxonomy provided.
