In the allied Spiranthes, or " Lady's-Tresses," a somewhat similar mechanism prevails, by which fertilization is largely effected by the changed position or angle of the stigma plane. And thus we might proceed through all the orchid genera, each new device, though based upon one of the foregoing plans, affording its new sur- prise in its special modification in adaptation to its insect sponsor—all these various shapes, folds of petals, positions, colors, the size, length, and thickness of nectary, the relative positions of pol- len and stigma, embodying an expression of wel- come to the insect with which its life is so mar- vellously linked. Occasionally this astounding.
