We learned that that Buttercup family lived within the petals of the Buttercup House. And we learned that the pollen from the stamen, or father, must reach the pistil, or mother, before the little eggs or seeds contained in the mother can begin to grow and develop into new plants. But the flower cannot move about as can animals, so they must depend on insects and outsiders to bring the pollen into the little nest where the eggs are. But unless there is some object attracting insects, bees, moths and butterflies, etc., to visit the flowers, they would not come to them, so the flowers have many attractions, such as their color and their odor. But the most important, and one which is sweet is the little bag of nectar or honey contained in many flowers which all insects love and will go far to get. When the insect visits the father, it rubs against his pollen, the pollen sticks to his head or legs. Then as he visits the mother, if the stigma (which is the top of the pistil, or mother) is ready for the pollen, it shows this by becoming moist, and sometimes sticky. Then the pollen clings to the stigma, and down it goes through its tiny tube, to the little nest of ovules, or seeds, where it mates and at once causes the seeds to become alive. Then they grow and grow until their time comes to burst forth and develop new plants themselves. Now, it is also important that the little visitors who come for the nectar, or honey, should fly from flower to flower and not crawl, because in doing so the pollen would drop off and never reach the mother flower, who is anxiously awaiting this important substance, so that the little seeds, or babies, may begin to grow. Consequently they have many ways of keeping out the crawling insects. Mrs. Buttercup has a very hairy stem, which makes a very hard journey for Mrs. Ant and others to come into the Buttercup house for a little sip of honey. She often starts there, but gets so tired out that she gives up the trip and returns to her family without any honey for them. This plan of growing a hairy stem is only one of the interesting ways the flowers have of keeping out the insects who cannot help them carry out the one object for which they exist—to make more flowers. Some of the flowers have a little trap door to their sac of honey, which only the weight of the bee can open. Others keep their nectar in long tubes, so that only bees with long tongues can reach it. An example of this is in the Orchid of Madagascar, which has a nectar tube eleven inches long, and depends upon one certain kind of moth for its existence.
