S ummaryTurner a subulata J. E. Smith is heterostylous with pin and thrum flower forms and is self–incompatible but cross‐compatible. Pin and thrum flowers produce the same number of pollen grains. Only 3·07% of the pollen produced participates in the pollination. Pin stigmas receive an average of 425 pollen grains and thrums 327. Stigmas of pin flowers receive more thrum than pin pollen grains. Thus in compatible pollinations, pollen flow from the thrum to the pin form was greater than in the reverse direction.
