Euploca is an almost cosmopolitan genus of plants with 168 species.[2][4] It was first described by Thomas Nuttall in 1837.[1][5] While part of the broadly defined Boraginaceae in the APG IV system from 2016,[6] a revision of the order Boraginales from the same year includes Euploca in the separate family Heliotropiaceae.[4] 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.[3] While many species use the C4 photosynthetic pathway,[7] there are also C3–C4 intermediate species.[8][9] Species have leaves with a C4-typical Kranz anatomy.[3]
