Orchid Flowers.—The flowers of orchids vary wonderfully in shape, size and color. Most of them are specially adapted to insect pollination. The distinguish- ing feature of the orchid flower, however, is the union of stamens and pistil in one body, known as the column. In Fig. 250 the stemless lady's-slipper is shown. The flower is 3-merous. One of the petals is developed into a great sac or "slipper," known as the lip. Over the opening of this sac the column hangs. The column is shown in detail: a is the stigma; d is an anther, and there is another similar one on the opposite side, but not shown in the picture; b mowrrvoF ElMCOirFKniBRARY.
