ABSTRACT = {Pollen morphology and the degree of pollen variability within nine species and two varieties
of <i>Oxalis</i> species from Buenos Aires Province (Argentina) were studied using light microscopy (LM), scanning electron microscopy (SEM) and transmission electron microscopy (TEM).<br/>
<i>Oxalis</i> pollen grain is generally 3-colpate and the shape is prolate spheroidal, oblate spheroidal or spheroidal. The exine is microreticulate. The brochi are circular to polygonal; brochi sizes decrease near the colpi.
The colpus membrane observed in unacetolysed material, is crustate or granular. The colpus length varies
within a species; the largest grains are produced in stamens with long filaments and the smallest ones in
stamens with short filaments.<br/>
Four pollen types are distinguished by means of LM, SEM and TEM. They are recognized mostly on the
basis of their colpus membrane structure.<br/>
In conclusion, the morphological similarity among <i>Oxalis</i> species is also reflected in their pollen morphology},
