--><p>Chylismiella was formerly included as a section in Oenothera (P. A. Munz 1928; P. H. Raven 1962, 1964) or Camissonia (Raven 1969), and elevated to generic rank based on molecular analyses of the Onagreae. Chylismiella was placed by R. A. Levin et al. (2004) sister to Gayophytum rather than with other groups placed by Raven (1964, 1969) in Camissonia. Chylismiella plus Gayophytum together have a sister relationship to Clarkia in the Levin et al. analyses. Raven (1969), in noting that Chylismiella pterosperma (as Camissonia) is extremely distinctive and not closely allied to other groups in Camissonia, suggested the possibility of a close relationship between Chylismiella and Gayophytum due to the shared character of white petals with a yellow band near the base, but did not suggest a close relationship with Clarkia. Chylismiella is distinguished by seeds with thick, papillate wings. Reproductive features include: self-compatible and flowers diurnal, mainly autogamous (Raven 1962, 1969).</p>
