摘要：
The genus Scrophularia in the Iberian Peninsula and Balearic Islands comprises two sections, Scrophularia and Canina G. DON. Analyses were carried out on flower production, flower duration and their sexual phases, pollen and nectar production together with observations on their pollinators. Nectar production is correlated with corolla size and pollen production with anther size. The taxa of sect. Scrophularia show greater nectar and pollen production than those of sect. Canina. Also, those of the first section produce more ovules per ovary than those of the second group, production being correlated with the ovary size.
