Escontria Rose in Contr. U.S. Natl. Herb. 10: 125. 1906 sec. Hernández & Gómez-Hinostrosa 2011



Phylogenetics: Monotypic, endemic to southern Mexico. Sampled by Arias & al. (2005), Bárcenas & al. (2011) and Hernández-Hernández & al. (2011). The latter two studies show E. chiotilla resolved together with Stenocereus species, while Arias & al. found E. chiotilla in a polytomy with Polaskia chichipe, Myrtillocactus and Stenocereus, but not nested in any other genus. So, maintaining Escontria as a separate genus may be justified, but generic limits within that clade need further evaluation.A
