The taxonomic treatment of agamosperms in the genus Limonium Mill. (Plumbaginaceae)

Agamospermous species account for a large proportion of the species of Limo nium. Agamospermy is indicated by uneven polyploidy or aneuploidy, low poll en stainability and by the presence of monomorphic self-incompatible popula tions. The taxonomic treatment of agamospermous taxa varies from recognitio n of all of them at the same specific rank or by utilising a range of ranks in the taxonomic hierarchy. The influence of evolutionary hypotheses on ta xonomic systems is considered. Molecular data provide a means of measuring the genetical relationships of taxa and establishing groups in a taxonomic hierarchy.
