Abstract

Epicuticular leaf waxes in the 12 taxa classified inSedum, sect.Gormania show variation in size, shape, and frequency. All of the taxa exhibit wax platelets, but the platelets in the three putative relicts (S. albomarginatum, S. moranii, S. oblanceolatum) are larger than those in related taxa, and those inS. paradisum are poorly developed. Interspecific hybrids tend to show wax patterns intermediate between those of their respective parents. Hypothetical hybrid origins for the four polyploid taxa in the section have been supported previously by morphological and reproductive data and are further clarified by leaf wax data.
