Estimates of interpopulational gene flow and the levels and distribution of genetic variation in Clarkia speciosa subsp. polyantha were obtained using enzyme electrophoresis. Eight enzymes encoded by 17 loci were analyzed. Nei's mean genetic identity was 0.96, indicating little genetic divergence among populations. Gene diversity statistics also suggest little heterogeneity among populations. Interpopulational gene flow, estimated according to Slatkin (1985), was fairly high, Nm = 3.9, probably accounting for the lack of differentiation among populations.
