Results of a field experiment in which plants were emasculated and exposed, with and without and hand pollination with and without enclosure in mesh sleeves (na = not applicable). For the "Untreated" specimens, mature seed capsules were selected from intact, undisturbed plants not included in the experiment; seed set was not recorded.
