We investigated the breeding and pollination systems of Hancornia speciosa, a small tree that produces fleshy berries used in the Brazilian fruit industry. Observation and experiments were carried out in Northeastern Brazil. Thirty-three species of the visitor were recorded. Hawkmoths (Sphingidae), bees (Euglossini and Centridini), and butterflies (Nymphalidae and Hesperiidae) with long mouth parts were effective pollinators of &lt;em&gt;H. speciosa&lt;/em&gt;. Access to nectar, the only reward for flower visitors, is determined by corolla tube length. Nylon threads of various diameters and dried mouth parts from a number of flower visitors were used in experiments to simulate flower visits. The number of pollen grains removed during such simulated visits showed no significant difference. Although xenogamic, &lt;em&gt;H. speciosa&lt;/em&gt; presented a low pollen/ovule ratio (77). This might be related to the high efficiency of its pollination mechanism. Flowers of &lt;em&gt;H. speciosa&lt;/em&gt; had 76 ovules on average. Seed set varied from 1 to 25, indicating that individual flowers received different amounts of outcross-pollen. Fruit production of hand cross-pollinated flowers increased by 90 percent when compared to natural pollination, suggesting pollinator limitation of &lt;em&gt;H. speciosa&lt;/em&gt;.&amp;quot;&lt;/p&gt;
