Abstract
Foram estudadas as tétradas polínicas de 9 espécies de Ericaceae ocorrentes no Estado de Santa Catarina. Entre elas destaca-se somente uma espécie, Gaultheria ulei, por ter tétradas menores que as deamis. Uma separação das outras espécies através o aspecto das superfícies de seus grãos de polén é possível somente entre grupos de espécies. O gênero que apresenta, relativamente, uma maior variação na morfologia polínica é Gaultheria. Desta maneira o estudo dos grãos de polén das Ericaceae examinadas, dificilmente poderá servir de caráter taxonômico na determinação das espécies.
The pollen tetrads of nine species of Ericaceae from Santa Catarina State have been studied. Between them only one especies of Gaultheria show smaller tetrads. The separation of the other species by pollen grain patterns is possible only between groups of species. Gaultheria was the only genus which present a relative greater variation on the pollen morphology. According to these results the study of the pollen grains of ericaceae seems to be not usefull in the taxonomy of species of this group.
