Abstract
This study contributes to the morphological characterization of Ombrophytum villamariensis, a new species of Neotropical Balanophoraceae recently described for Colombia. The study revealed the presence of diagnostic characters in the pollen grain such as small size and a circular endoaperture. Unlike other species, only tricolporate pollen grains were observed.
