Abstract

Pollen from staminate flowers and pistillate flowers with “staminodes” of Phyllanthus acidus Skeels were analyzed under scanning electron microscopy, and tests of pollen viability and in vitro germination were carried out to verify possible similarities between the three types of flowers. The results show that pistillate flowers with “staminodes” are bisexual, indicating the occurrence of trimonoecy in this species.
