Cypripedium

[Gr. Kypris, Venus, and podiona slipper; from the slipper-like form of the lip.] ( Bot. ) The Ladies'-slipper, a genus of plants, order Orchid ace a. The species are chiefly distinguished by their large, very showy flowers, with large inflated lower petal or lip. The species C. candidum, white-flowered ladies's lipper, C. acaule, acaulescent ladies'-slipper, C. parvi florum, yellow ladies'-slipper, are natives of this country. C. arietinum, the Ram's-head, found in damp woods, from Canada to Vermont, has a stem clustered, flexuous, 8-12 inches high; remarkable for the singular form of the lips, which readily suggests the name of this curious plant.
