Euploca

168; see text Euploca is an almost cosmopolitan genus of plants with 168 species.

[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.

[8][9] Species have leaves with a C4-typical Kranz anatomy.
