In the center a fruiting flower, on both sides of it several pollen flowers in the most different stages of development, partly still closed, partly in the process of opening, partly open with folded down, skull-shaped petals. The pollen leaves rise from the opened flowers. An open anther attaches its pollen to the fringed stigma of the fruit flower., Vallisneria spiralis, (botany book, 1905), Wasserschraube, Blüten, auf dem Wasserspiegel schwimmend.

The pistillate flower is solitary upon a long stalk, which, rising from the leaf axils, elongates very rapidly until the flower floats on the water surface, when the stigma is soon exposed to receive the pollen from the passing boats of staminate flowers (Fig. 254, page 181, and Fig.
