Unlike flowering plants, ferns reproduce with spores instead of seeds. Fern spores are contained in sporangia which are found on the leaf surface in clusters called sori (singular: sorus). 

Fern sori come in all shapes, sizes, and locations. They may appear as dots, dashes, or lines on the leaf surface. They can occur tucked under the leaf edge, arrayed in patterns on the underside of the leaf, or on separate spore-bearing leaflets.

All the ferns in this collection have round sori that dot the undersides of the leaves. Classic polka dots never go out of style.
