A pair of exceedingly large, shining, circular leaves with a silvery underside and lying flat upon the ground, are pretty certain means of identifying this peculiar Orchid. It frequents deep, rich woods, preferably evergreen, which are carpeted with pine or hemlock needles, where it raises its stout stalk a foot or two high, and blossoms gaily during July and August. From ten to twenty or more white flowers are loosely clustered in a terminal spike. The short, upper sepal is rounded, and the two narrower side ones are spreading. Two petals are smaller, sharply pointed and arching, while the long, narrow, and drooping white one, which forms the pointed, curving lip, is prolonged in a long, slender, curving spur. The great, opposite spreading leaves are many-ribbed, and the stalk has several small, alternating bracts or leaflets set along its length. This Orchid is rather uncommon, and is found in the hilly or mountainous regions, from the British Possessions south to North Carolina and Minnesota.
