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]
168 species are accepted. [2]
