Pollen grains of most known species of Epacris in Australia were examined by scanning electron microscopy. There is a range of pattems of surface ornamentation present, based upon which the species can be grouped into two broad classes: (l) "smooth", in which the tectum is essentially intact but pitted and rugulate to varying degrees; (2) "warted", in which the pollen is intectate with a range of surface processes generally >2µm. The patterns are useful at the interspecific level to delimit certain taxa with morphological overlap.
