Pollen morphology of Coris (Primulaceae)

Pollen grain morphology, sculpturing, and wall ultrastructure were investigated in Coris (Primulaceae). This genus can be distinguished from the remaining members of the family by the conjunction of relatively large pollen grains, prominent margo, and particular tectal pattern causing a reticulate surface with minute luminal perforations decreasing towards the colpi. From both these distinctive features, and others typically primulaceous, some evolutionary considerations can be inferred. The higher proportion of irregular grains in C. hispanica can be interpreted in light of environmental stress.
