Abstract

This study compares Herissantia tiubae with 10 species of Gaya H.B.K, and Herissantia Medicus. The pollen morphology of the eleven species is described in detail by observations from both the scanning electron and light microscopes. The palynological data were used to produce pollen descriptions and a phenogram based on similarity coefficients. This information was combined with morphological and cytological data to determine the taxonomic relationship and proper placement of H tiubae, which has the pollen characteristics of Herissantia and is properly placed in that genus.
