A biometric survey of Limonium vulgare Miller and L. humile Miller in the British Isles

239 Limoniurn vulgare Miller and L. hurnile Miller (Plumbaginaceae) are closely related species that grow on saltmarshes around the coasts of northern Europe including the British Isles. They are often found together in the same marsh. Morphometric analyses were performed on plants collected from sites around the British Isles. This demonstrated the close relationship of these two species and provided strong evidence for hybridization and introgression in sites where both species were present
