Fig. 9.—Stamens and stigmas of Malva sylvestris. Fig. 10.—Ditto of Malva rotundifolia branches of the stigma are elongated, and twine them- selves (Fig. 10) among the stamens, so that the flower readily, fertilises itself. Another interesting case is afforded by the genus Epilobium. Epilobium angustifolium has large pur- plish flowers in conspicuous heads (Fig. 11), and is much frequented by insects; while E. parviflorum (Fig. 12) has small solitary flowers and is seldom visited by insects. Now in the former species their visits are necessary, because the stamens ripen and.
