Abstract:Summary Seed obtained from two or three individuals in an extensiveHeterophylla population produced plants with a total of six S-factors. The number of different S-factors in the population as a whole is probably very large, and this increases very greatly the likelihood of successful pollinations among the individuals of this self-incompatible race.Dedicated to Professor Dr.Fr. Oehlkers on the occasion of his 70th birthday with respect and best wishes.Supported by the Rockefeller Foundation.
