Pollen morphology of three Chinese monotypic endemic genera in Gesneriaceae was studied by light microscopy (LM) and scanning electron microscopy (SEM). All three taxa are similar in having prolate to subspheroidal pollen grains,but with different exine sculpture patterns: Allostigma guangxiense with coarsely reticulate, Dolcholoma jasminiflorum and Primulina tabacum with finely reticulate pattern,suggesting a clear difference between them. The utility and systematic significance of some pollen characters in Gesneriaceae were also discussed.
