SUMMARY Three closely related pseudogamic species, Potentilla argentea L., P. recta L. and P. cf. hirta L. were pollinated by other species of Potentilla and observations were made on pollen germination, pollen tube growth, ovule development and seed set. The three pseudogamic species stimulated seed set in each other, but no seeds were formed after pollination by ten other species although well‐developed pollen tubes were observed in a number of cases. The offspring from the successful pollinations were mainly maternal but a few deviant individuals were also produced.
