Abstract

Pollen morphology of native and introduced Cruclferae in the North East of Argentina. The present paper describes the more pertinent features of the pollen morphology, uslng light and scanning electrón mlcroscopy, of 15 genera and 27 species whlch Uve ¡n the North East of Argentina; only 6 genera and 13 species are native. The pollen gralns present little variations, wlth respect to their slze, shape and exlne sculpture, whlch conflrms the stenopalynous character of thls famlly. A key is presented in orde to ¡dentlfy the genera and species.
