Abstract Pollen morphology and the degree of pollen variability within nine species and two varieties
of Oxalis species from Buenos Aires Province (Argentina) were studied using light microscopy (LM), scanning electron microscopy (SEM) and transmission electron microscopy (TEM).
Oxalis 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 More >
