It has been 30 years since Baker (1967) reemphasized in these pages the significance of what Stebbins (1957) had termed "Baker's Law," namely, that it is more likely for self-compatible than for self-incompatible individuals to establish a sexually reproducing colony after "long-distance" dispersal, because only the former can do so with a single individual (Baker 1955, 1967).
