Vernacular names

Euploca is an almost cosmopolitan genus of plants with around 100 species.[3] It was first described by Thomas Nuttall in 1837.[1][4] While part of the broadly defined Boraginaceae in the APG IV system from 2016,[5] a revision of the order Boraginales from the same year includes Euploca in the separate family Heliotropiaceae.[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] While many species use the C4 photosynthetic pathway,[6] there are also C3–C4 intermediate species.[7][8] 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
