Their habit of closing both in
the evening and in rainy weather indicates that they are adapted
for diurnal insects only; but if the bell hang down, or if the
corolla drop off, the pollen must fall on the stigma and effect
self-fertilization. Many more insects visit this flower than the
large bindweed, attracted by the peculiar fragrance, and led by
the white streaks to the orange-colored under surface of the
ovary, where the nectar lies concealed. Stigmas and anthers
mature at the same time; but as the former are slightly the
longer, they receive pollen brought from another flower before
the visitor gets freshly dusted.
