Fruit set was low in the three species. The distribution of fruits in the non-autogamous species was skewed to the right, with high variance:mean ratios, and a moderate to high proportion of fruitless plants. Larger inflorescence size did not necessarily result in an increase in percent fruit set but tended to increase the probability to produce at least one fruit. Pollinator-mediated selection on inflorescence size through fruit production may be limited by the low overall level of visitation and the resulting uncertainty of pollination at the individual level.}, issn = {00029122}, doi = {10.2307/2444598}, url = {http://www.jstor.org/stable/2444598}, author = {Ricardo N.
