Abstract in another language
Macro- and micromorphological characters of the seeds of 32 species belonging to Aizoaceae (26 species), Gisekiaceae(one species) and Molluginaceae (five species) were analysed for their taxonomic value. Seed morphology is found to be of considerable taxonomic value within the taxa investigated, although additional criteria are usually necessary for distinguishing the species. However, a subgroup of Trianthema, consisting of T. cussackiana, T. megasperma, T. pilosa, T. rhynchocalyptra and T. oxycalyptravar.oxycalyptra(Aizoaceae) shares the synapomorphy of seeds with scattered idioblast cells (papillae). There is little infrageneric variation within Sesuvium and Zaleyain contrast to Trianthema, whose seeds are considerably polymorphic. The fairly different seed structures found in Aizoaceaes.s. and Molluginaceae support their treatment as two distinct families. However, the position of Lineum(Molluginaceae) remains uncertain. Moreover, seed characters support the independence of Gisekia(Gisekiaceae)in a family of its own.
