Short summary
Ouratea spectabilis is a tree in the Brazilian savannas, or cerrados. Only a few specialized insects can produce the specific vibrations to liberate their pollen, in what is known as "buzz pollination". It is self-incompatible, and self-pollination reduced fertility to the level of interspecific crosses with co-generic species. Pollen viability was high, but in spite of pollen supplementation seed-to-ovule ratios were never over 30%, likely because of environmental stress.
