Abstract

Pollination is described for six orchid species. Eulophia alta is autogamous. The advantages and disadvantages inherent in a population reproducing by this mode are discussed. The remaining species require an animal vector for successful reproduction. The floral mechanisms responsible for the attraction and the proper positioning of these vectors for pollination are stressed. Additional mechanisms which increase the chances for outcrossing are included. For Epidendrum difforme and the Inagua encyclias, evolutionary implication of the pollination systems are discussed. For the latter group it is explained why a wide variety of non-pollinating visitors are unable to operate the pollination mechaniams. Pollination was not observed for Encyclia altissima and Encyclia rufa.
