--><p>Eulobus is characterized by olive brown seeds with distinct purple spots, yellow petals with maroon flecks near the base, the distal part ultraviolet-reflective, leaves mostly lobed or pinnatifid, and capsules somewhat contorted or straight, and often sharply reflexed at maturity. R. A. Levin et al. (2004) included E. californicus and E. crassifolius (Greene) W. L. Wagner & Hoch (a species of Baja California, Mexico) in their molecular analysis and found Eulobus to be strongly supported as monophyletic; they also found that Eulobus plus (Chylismia plus Oenothera) formed a weakly supported clade. Reproductive features include: self-incompatible [E. crassifolius, E. sceptrostigma (Brandegee) W. L. Wagner & Hoch] or self-compatible [E. angelorum (S. Watson) W. L. Wagner & Hoch, E. californicus], flowers diurnal, outcrossing and pollinated mainly by small oligolectic bees (E. G. Linsley 1963b, 1973) or autogamous (P. H. Raven 1969).</p>
