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

Description

[edit]

While many species use the C4 photosynthetic pathway,[5] there are also C3–C4 intermediate species.[6][7] Some species have leaves with a C4-typical Kranz anatomy.[3]

Taxonomy

[edit]

The genus was first described by Thomas Nuttall in 1837.[1][8] While part of the broadly defined Boraginaceae in the APG IV system from 2016,[9] 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]
