Abstract

The objective of the following work is to expand the palynological knowledge of the species belonging to the genus Erythrina (Fabaceae) present in Argentina, in order to provide data that will allow the delimitation of these taxa, and incorporate this information into the NOA Pollinic Atlas (http://www.lillo.org.ar/atlaspolinicodelnoa/). The species analyzed were: E. crista-galli L., E. dominguezii Hassl, E. falcata Benth, E. poeppigiana (Walp.) O. F. Cook and E. similis Krukoff. The material was processed according to conventional techniques for acetolized and non-acetolized pollen. Photos were taken with optical level microscopy (MO) and scanning electron microscopy (MEB). The results show that the grains are medium from 22 to 45 µm in non-acetolysed pollen and from 24 to 46 µm in acetolysed pollen, Oblates to Oblates-spheroidal, 3-porados in E. crista galli, E. similis and E. falcata and 3-4-porados in E. dominguezzi and E. poeppigiana. The exine varies from 1.5 to 3 µm thick, increasing in size in the area of the equator. It presents a reticulate heterobrochate wall ornamentation, with variation in shape of the lumens, in the height and width of the walls, and the existence and prominence of the granules. The ornamentation of the exine observed with MEB allows to differentiate the studied species.
