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> |tables= |references= }}<!-- --><!-- -->{{#Taxon: name=Eulobus |author=Warren L. Wagner |authority=Nuttall ex Torrey & A.
