; Sp. Pl. [Linnaeus] 15 (1753), nom. cons.
Distribution: Tropics and subtropics, with a center in Mexico (103). The genus is taken here in a broad sense (Graham 1988), except Rostellularia and Dianthera. It remains highly polyphyletic and needs complete rearrangement (Kiel et al. 2017). Leptostachya is certainly separate, but it is unclear which species really belong into it.
