Eulychnia Phil., Fl. Atacam.: 23. 1860 sec. Larridon & al. 2018



Phylogenetics: Species boundaries and infrageneric relationships in Eulychnia have recently been comprehensively studied using six chloroplast markers (rpl32-trnL, trnH-psbA, trnL-trnF, trnQ-rps16, trnS-trnG, and ycf1) and a sampling covering the distribution range (Larridon & al. 2018). Eulychnia was confirmed as monophyletic and two major clades were retrieved in the molecular phylogenetic hypotheses, a northern clade and a southern clade, which both can also easily be distinguished morphologically. The results also supported accepting three further species E. ritteri, E. chorosensis and E. taltalensis, together with the recognition of the new species E. vallenarensis.
