have been reported in Texas to yield nectar; but all flower ecologists describe them as pollen-flowers. They are visited by bees exclusively for pollen, which is very abundant. On top of the stigma, when the flower first opens, there is a large drop of water. This drop of water is not sweet and is not gathered by bees, although small bees are sometimes drowned in it. By the second day it has dried up. The large flowers are often very abundant in small ponds and are visited by honeybees in great numbers for pollen. In the yellow cow-lily (Nymphaea advena) nectar is secreted on the outer side, near the top of the short thick petals, the nectariferous portion being orange-colored. No honeybees, however, have been observed to visit the flowers in Maine, Illinois, Wisconsin, Florida, and Germany.
