The Grass-Pink (_Limodorum tuberosum_) is much more attractive, with its rose and pink-purple blossoms. The spike, often a foot high, bears from two to fifteen beautiful and slightly fragrant flowers. The origin of the generic name, _Limodorum_, comes from the Greek, meaning “a meadow gift.” These flowers, according to Mr. Coleman, are called Grass-Pinks in Michigan, while Thoreau also called them by the same name in Massachusetts.[28] The labellum seems hinged at the insertion, and is bearded with yellow and purple hairs. There is seldom more than one freshly blown blossom on the stalk at a time, and thus the plant remains attractive for some days. Beginning at the lowermost bud, each one takes its turn in unfolding, the spike slowly lengthening while the buds constantly increase in size and color. One interesting peculiarity of this species is that it remains as Nature originally intended all species of orchids,—with the labellum as the _upper_ petal, instead of the lower, as seen in all other native species. It will be observed in species of the Orchid Family that a twist of the seed-pod has taken place: if not a complete revolution, at least half a turn. The labellum is, therefore, directed forward on the lower or inferior side, as in the species of Cypripedium, where it appears in the position of a shoe or moccasin, instead of holding itself above like a dome, as originally intended by Nature. Darwin says of this: “An enormous amount of extinction must have swept away a multitude of intermediate forms, and has left this single genus, now widely distributed, as a record of a former and more simple state of the great Orchidean Order.”[29] The ovary of the Grass-Pink is straight, and the labellum so hinged that it falls down like an arch above, bearded with delicate hairs. The column bearing the anther, containing four soft pollen-masses, curves slightly at the end, producing a hollow wherein lies the pollinia. The stigmatic surface lies still farther toward the centre of the column. An insect sipping nectar from these flowers, safely enters without distributing the adhesive pollinia, since the anthers containing the cells are so hinged that not until he turns to leave the heart of the flower does he swing open the lid of the cup containing the powdery gold, which fastens to the velvet of his coat beneath his body. The next flower of this species, therefore, becomes fertilized properly, and in turn unlocks her treasure-store as the insect backs off the keel of the pollen mass. Professor Meehan writes that this plant “rarely fails to produce perfect seed-vessels. Yet it is seldom that plants which depend on insects for their supply of pollen, as these are supposed to do, and which are not fertilized by their own pollen, produce seeds from every flower.”[30] [Illustration: =The Grass-Pink.= (_Limodorum tuberosum._)
