Pollen morphology of Proteaceae native to Argentina

Damián Andrés Fernández


Pollen morphology of the eight species of Proteaceae native to Argentina are studied using light and electron scanning microscopes. These species are: Embothrium coccineum, Gevuina avellana, Lomatia dentata, L. ferruginea, L. hirsuta, Orites myrtoidea, Roupala meisneri and R. montana. The characters which have been useful to recognize species or genera are: ornamentation, pores number, equatorial diameter, ratio sexine/nexine thickness and ratio equatorial diameter/pore diameter. Using these characters a dichotomous key to these proteaceous species is presented.
