Cypripedium acaule is a member of the orchid genus Cypripedium. Carl Linnaeus (Latinized as Carolus Linnaeus, also known after his ennoblement as, May 23 new style (13 May old style 1707 who laid the foundations for Cypripedium is a Genus of 47 species from the Orchid family (Orchidaceae and the sole genus of the Subtribe Cypripediinae. Members of this genus are commonly referred to as Lady's Slipper orchids. Lady Slippers (aka Lady's Slipper, Lady's-slipper, Ladyslipper) is a term used to describe the orchids in the subfamily Cypripedioidea First described in 1700, Cypripedium acaule is commonly referred to as the Pink Lady's Slipper. An alba variety exist which has a white lip instead of a pink one. The Pink Lady's Slipper is the provincial flower of Prince Edward Island, Canada.
In Nova Scotia, Canada it is a protected plant, and it is endangered.

Description
Unlike most other members of Cypripedium, the pouch of C. acaule opens in a slit that runs down the front of the labellum rather than a round opening. The labellum (or Lip) is part of an Orchid, Canna or other less known flower that serves to attract Insects that Pollinate the flower The plant consists of two plicate leaves near the ground. From between those leaves sprouts a long, pubescent stalk that bears a single pink flower. The sepals and petals tend to be yellowish-brown to maroon with a large pouch that is usually pink, but is sometimes solid white
Range
C. A sepal (from Latin separatus "separate" + petalum "petal" is a part of the flower of Angiosperms or flower plants A petal (from Ancient Greek petalon "leaf" "thin plate" regarded as a highly modified leaf is one member or part of the corolla acaule can be found in the eastern third of the United States and north into Canada, coming very close to the arctic circle. The Arctic Circle is one of the five major circles of latitude that mark maps of the Earth. This widespread species can be found in a wide variety of environments: from coastal plains to pine barrens to mountain tops. However, it prefers its soil to be highly acidic and can usually be found where pine trees provide a groundcover of needles.
Habitat
C. acaule grows in a variety of different habitats, including moist and dry soils. It is usually found in pine forests, where it can be seen in large colonies, but it grows in deciduous woods, as well. It is nearly always found in soil with high acid content. Because of a fungus association needed for growth, and the high acid this plant needs, C. acaule is very difficult to grow in the average garden and is unlikely to survive any attempts at transplantation. Additionally, although this species is common in parts of the northern United States and Canada, it is considered endangered in Illinois and Tennessee and should not be removed or disturbed if found in nature [1].
