Seed germination ecology of Veronica species (Scrophulariaceae) from SW Spain. Seed germination and viability were studied in severa l species of Veronica. Laboratory germination experiments at 22±2 °C showed a different response in light and the dark. In light, V. anagallis-aquatica, V. anagalloides, V. arvensis, V. persica and V. polita achieved high germination rates (greater than 80%), while others such as V. cymbalaria, V. hederifolia, V. peregrina, V. praecox, V. scutellata and V. triphyllos significantly reduced seed germination (lower than 20%). Seed germination percentage of V. cymbalaria, V. hederifolia and V. peregrina increased significantly in the dark. Seed viability was very high by all species (from 81% to 100%). The relatinships between seed germination requeriments and species habitat is discussed.
