The bright petals, especially the upright standard, attract the bee, which alights astride the wings, thus depressing both wings and keel until the end of the pistil comes in con- tact with the under surface of the bee. In the meantime, the tongue of the bee has been inserted into the base of the flower, from which it sucks the nectar, and then flies to another blossom, car- rying pollen with it. If you will watch 3-our sweet pea flowers a short time on a bright day, you will see, however, that the bees seldom alight astride the keel of our modern varieties when they visit the flowers.
