| Abstract: | A general survey of pollen morphology in Hydrophyllaceae, using scanning electron microscopy, is presented. Hydrophyllaceous pollen grains are relatively homogeneous, tricolpate or tricolporate, and with a tectate-perforate to semitectate exine structure. Surface ornamentation is basically reticulate, but varies sufficiently from genus to genus, and sometimes from species to species, to permit interesting comparisons, but not to draw profound phylogenetic conclusions. |
