Euploca is a genus of plants in the Boraginaceae family, first described by Thomas Nuttall in 1837.^[1]^[3] Its species used to be classified in the genera Hilgeria and Schleidenia and in Heliotropium sect. Orthostachys, but were found to form an independent lineage in a molecular phylogenetic analysis, more closely related to Myriopus than to Heliotropium.^[2] The genus is widespread, found both in the Old and New World.^[2] While around 130 species use the C₄ photosynthetic pathway,^[4] there are also C₃–C₄ intermediate species.^[5]^[6] Species have leaves with a C₄-typical Kranz anatomy.^[2]

Selected species:

E. convolvulacea Nutt. (sweet-scented heliotrope, showy heliotrope)
E. filiformis (Lehm.) J.I.M.Melo & Semir
E. salicoides (Cham.) J.I.M.Melo & Semir
