Cypripedium calceolus is a lady's-slipper orchid, and the type species of the genus Cypripedium . It is native to Europe and Asia.
Cypripedium comes from the Greek Κύπρις πεδίον (Kypris pedion), meaning Aphrodite's foot (a reference to the goddess Aphrodite, equivalent to the Roman Venus). [3] calceolus is Latin for a small shoe. [4]
Cypripedium calceolus sensu stricto ("in the strict sense") does not occur in North America. The closely related Cypripedium parviflorum and C. pubescens are often still referred to as subspecies or varieties of C. calceolus.
This is the largest-flowered orchid species in Europe, growing to 60 cm tall [5] with flowers as wide as 9 cm. [6] Before it flowers, it is distinguished from other orchids by the large size and width of its ovate leaves (as big as 18 cm long, 9 cm wide), [5] which like other orchids exhibit parallel venation. Each shoot has up to four leaves and a small number of flowers (typically one or two), which have long often twisted petals varying from red-brown to black (rarely green) and a slipper-shaped yellow labellum, within which red dots are visible. [5] It is a long-lived perennial [5] and spreads using horizontal stems (rhizomes). [5]
Cypripedium calceolus can be confused, when not flowering, with Allium ursinum , Convallaria majalis or several species of Epipactis orchid. It closely resembles other species of Cypripedium orchid native to the United States (see taxonomy).
Chromosome number has been given as 2n=20 but also 2n=22 [7]
It has a widespread distribution from Europe east through Asia from Spain to the Pacific, including almost every country in Europe plus Russia (European Russia, Siberia, and the Russian Far East), northeastern China (Heilongjiang, Jilin, Liaoning, Nei Mongol), Mongolia, Korea and Rebun Island in Japan. [2] [8] [9]
It is typically found in open woodland on moist calcareous soils. In continental Europe it is also found growing in the decomposed humus of semi-shaded woodland cover on limestone. It has declined over much of the European part of its range, and as a result is legally protected in a number of countries. Its upper elevation limit is 2,100 metres (6,900 ft). [1]
Cypripedium calceolus is frequently associated with stands of hazel trees. [10]
It is pollinated by a number of different insect species, including at least seven species of miner bee in the genera Andrena and Colletes , as well as at least two species of Lasioglossum (furrow bees). [10] Plants are very vulnerable to herbivory by slugs and snails.
Cypripedium calceolus is known to primarily associate with mycorrhizal fungi in the genus Tulasnellaceae . [11] [12] Specific relationships with mycorrhizal fungi are key to orchids' ability to access soil nutrients. Other suggested mycorrhizal partners include Alternaria sp., Ceratorhiza sp., Chaetomium sp., Cylindrocarpon sp., Epicoccum purpureum , Epulorhiza sp., Moniliopsis sp., Mycelium radicis atrovirens, Phoma sp. and Rhizoctonia subtilis sp. [13]
Although the global conservation status of Cypripedium calceolus is least concern according to the IUCN Red List, [1] in many countries (including the UK and Denmark) it has become rare and is afforded legal protection. C. calceolus is common in Poland and Austria but in Greece it has become extinct. [5]
In Britain, it was formerly a reasonably widespread plant across northern England, particularly the limestone area of the Yorkshire Dales. [14] By the late 20th century it had declined to just a single plant in one location in the Dales. [15] While the virtual extinction of the lady's-slipper orchid from its historical range in Britain is often blamed on uprooting by gardeners and botanists, it is also the case that its preferred habitat shrank markedly with human clearance of woodland from the limestone landscape, and the grazing of sheep will have finished it off. [16] It became a protected species in the UK in 1975 under the Conservation of Wild Creatures and Wild Plants Act, [17] but a reintroduction programme for the lady's-slipper orchid is in place, [18] [19] and has led to a population of hundreds of plants as of 2003. [20]
With the help of Dutch plant breeder and wholesaler Anthura, who made the Genus and this species commercially available in garden centers, this species is successfully reintroduced in several locations in Switzerland at the request of the Swiss Orchid Foundation. Seeds from the Swiss population were used by Anthura resulting in three thousand viable plants available for the reintroduction. The locations are kept secret, but are monitored regularly.

Cypripedium calceolus has appeared on postage stamps in a huge number of countries including Austria, the Czech Republic, Denmark, France, Grenadines, Hungary, Italy, Latvia, Madagascar, Moldova, Mozambique, Norway, Romania, Russia, Slovenia, Sweden, Uganda, Ukraine and the United Kingdom. [21]
The Norwegian municipality of Snåsa has a Cypripedium calceolus in its coat-of-arms.
In Pavel Ivanovich Melnikov's "In the Forests", a znakharka (Russian wise woman) calls this Adam's head, Adam's grass, and Cuckoo's slippers and says it is good for every ill including driving away evil spirits.
Cypripedioideae is a subfamily of orchids commonly known as lady's slipper orchids, lady slipper orchids or slipper orchids. Cypripedioideae includes the genera Cypripedium, Mexipedium, Paphiopedilum, Phragmipedium and Selenipedium. They are characterised by the slipper-shaped pouches of the flowers – the pouch traps insects so they are forced to climb up past the staminode, behind which they collect or deposit pollinia, thus fertilizing the flower. There are approximately 165 species in the subfamily
Cypripedium is a genus of 58 species and nothospecies of hardy orchids; it is one of five genera that together compose the subfamily of lady's slipper orchids (Cypripedioideae). They are widespread across much of the Northern Hemisphere, including most of Europe and Africa (Algeria), Russia, China, Central Asia, Canada the United States, Mexico, and Central America. They are most commonly known as slipper orchids, lady's slipper orchids, or ladyslippers; other common names include moccasin flower, camel's foot, squirrel foot, steeple cap, Venus' shoes, and whippoorwill shoe. An abbreviation used in trade journals is "Cyp." The genus name is derived from Ancient Greek Κύπρις (Kúpris), an early reference in Greek myth to Aphrodite, and πέδιλον (pédilon), meaning "sandal".
Calypso is a genus of orchids containing one species, Calypso bulbosa, known as the calypso orchid, fairy slipper or Venus's slipper. It is a perennial member of the orchid family found in undisturbed northern and montane forests. It has a small pink, purple, pinkish-purple, or red flower accented with a white lip, darker purple spottings, and yellow beard. The genus Calypso takes its name from the Greek signifying concealment, as they tend to favor sheltered areas on conifer forest floors. The specific epithet, bulbosa, refers to the bulb-like corms.
Cephalanthera rubra, known as red helleborine, is an orchid found in Europe, North Africa and southwest Asia. Although reasonably common in parts of its range, this Cephalanthera has always been one of the rarest orchids in Britain.
Ophrys insectifera, the fly orchid, is a species of orchid and the type species of the genus Ophrys. It is remarkable as an example of the use of sexually deceptive pollination and floral mimicry, as well as a highly selective and highly evolved plant–pollinator relationship.
