Neomillspaughia in Bull. Torrey Bot. Club 48: 84. 1921 sec. Brandbyge (1993)
With only two recognized species, the genus is restricted to the dry forests of Mexico and Central America (Brandbyge 1993; Burke & al. 2010). Previous to their assignment to a new genus by Blake (1921), species of Neomillspaughia had been placed in either Campderia Benth. (Donnell Smith 1899) or Podopterus (Gross 1913). Roberty & Vautier (1964) included Neomillspaughia in the genus Podopterus; however, based on molecular data Neomillspaughia receives strong support as sister to Coccoloba (Sanchez & al. 2009; Burke & al. 2010).
