	abstract = {The pollen morphology of 30 Boraginaceae taxa native to the Santa Catarina State was investigated by both light and scanning electron microscopy. The species were classified into nine pollen types on the basis of aperture characteristics and surface ornamentation. Sub-types were defined with regard to differences in shape, surface ornamentation and the number of apertures. The general agreement of these pollen types with taxonomic classifications was verified, with a few exceptions. An extensive re-evaluation of the systematics of the subfamily Heliotropioideae, especially of the genus Heliotropium, is suggested.},

Eighty-one species are recognised for the area, of which 78 are regarded as indigenous (75 endemic) with the remaining three species believed to be of recent introduction. Of the 51 new names proposed, 50 are the result of the description of new species. The remaining new name is required due to a change in status. Biological aspects briefly mentioned include breeding system and myrmecochory.},
