Notes

The genus is monophyletic (Sánchez del-Pino & al. 2009; Borsch & al. 2018) with approximately 45 species all of which are characterized by Iresine-Type pollen (Borsch 1998). The two species formerly classified as Dicraurus on the base of alternate and not opposite leaves are nested within the Iresine clade, confirming the merger by Henrickson & Sundberg (1986). Their dense indumentum with branched trichomes appears to be an adaptation to the dry habitats of northern Mexico.A,B,C,D,E
