Abstract
On the basis of a study of 22 of 30 species representing 12 sections of Silene in Jordan, we find that the seed coats exhibit considerable anatomical diversity, particularly the exotesta and mestotesta. Equivocal relationships are demonstrated for species with essentially identical seed features and seed coat sculpturing. Outer layers of the seed appear to be more open to adaptive modifications than inner ones.
