Cypripedioideae genera range |
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 . [1] They are characterised by the slipper-shaped pouches (modified labella) 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.[ citation needed ]
All representatives of the Cypripedioideae are perennial, herbaceous plants. The fleshy roots sometimes possess a veil. The leaves are arranged spirally or in two rows, the shoot is slender or compressed. In the bud, the leaves are rolled and the leaf blade is plikat (folded) or the leaves are folded in the bud, smooth and leathery. There is no dividing tissue between leaf and shoot.[ citation needed ]
The inflorescence of the Cypripedioideae are terminal and mostly unbranched. The flowers are spiral or in two lines on the shoot, they are resupinated. The petals are in two threefold circles, with mostly two petals of the outer circle are completely fused. The labellum forms a sac-like structure. The ovary is under constant and one-chambered or three-chambered. Two fertile stamens, a staminode and style are fused into a complex structure. The stylus is short and thick, the stigma is large and convex, the central lobe of the stigma is larger than the two lateral ones. The two lateral stamens are fertile, the pollen grains are glued together to form a paste or formed into connected pollinia in some Phragmipedium species. The middle, barren stamen is shield-shaped widened. The fruits are mostly capsule fruits, with Selenipedium they are berry-like. They contain numerous flattened seeds, about a millimeter long and 0.1 millimeters wide. In contrast, the seeds of Selenipedium are lens-shaped and have a hard seed coat.[ citation needed ]
Chromosome numbers vary within the subfamily over a wide range from 2n=20 in Cypripedium to 26 to 44 chromosomes in Paphiopedilum . The chromosomes are quite large.[ citation needed ]
The species in this subfamily form trap flowers in which insect access to the saclike lip from the front is quite easy. The inside is designed in such a way that the insects climb out of the flower past the stigma and the stamens and thereby pollinate the flower.
The species in the subfamily Cypripedioideae are found in northern South America and Central America (Mexipedium, Phragmipedium, Selenipedium), circumboreal in North America, Europe, Africa (Algeria [2] ) and in northern Asia (Cypripedium) as well as in subtropical and tropical Southeast Asia (Paphiopedilum). They do not occur in Australia and Africa. The spread could have started from a center of origin in Central America.[ citation needed ]
Unlike most other orchids, slipper orchids have two fertile anthers — they are "diandrous". For that reason, experts have debated whether this clade should be classified within the orchid family (Orchidaceae), or whether they should compose a separate family altogether called Cypripediaceae. [3] Around the year 2000, molecular phylogenetics and DNA sampling have come to play an increasingly important role in classification. [4] This has led to the conclusion that recognition of a distinct family Cypripediaceae would be inappropriate. [5]
The subfamily Cypripedioideae is monophyletic and consists of five genera:
Hybrids between the genera in this subfamily are placed in the following nothogenera: [7]
Hybrids with genera outside of the subfamily are not known as of 2017.
Orchids are plants that belong to the family Orchidaceae, a diverse and widespread group of flowering plants with blooms that are often colourful and fragrant. Orchids are cosmopolitan plants that are found in almost every habitat on Earth except glaciers. The world's richest diversity of orchid genera and species is found in the tropics.
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".
Paphiopedilum, often called the Venus slipper, is a genus of the lady slipper orchid subfamily Cypripedioideae of the flowering plant family Orchidaceae. The genus comprises some 80 accepted taxa including several natural hybrids. The genus is native to Southeast Asia, the Indian Subcontinent, southern China, New Guinea and the Solomon and Bismarck Islands. The type species of this genus is Paphiopedilum insigne.
Phragmipedium is a genus of the Orchid family (Orchidaceae) and the only genus comprised in the tribe Phragmipedieae and subtribe Phragmipediinae. The name of the genus is derived from the Greek phragma, which means "division", and pedium, which means "slipper". It is abbreviated 'Phrag' in trade journals.
Mexipedium is a monotypic genus of the Orchid family Orchidaceae, subfamily Cypripedioideae, consisting of only one species, Mexipedium xerophyticum. It is also the single genus of tribe Mexipedieae and subtribe Mexipediinae.
The taxonomy of the Orchidaceae (orchid family) has evolved slowly during the last 250 years, starting with Carl Linnaeus who in 1753 recognized eight genera. De Jussieu recognized the Orchidaceae as a separate family in his Genera Plantarum in 1789. Olof Swartz recognized 25 genera in 1800. Louis Claude Richard provided us in 1817 with the descriptive terminology of the orchids. (See External links below). The next step was taken in 1830-1840 by John Lindley, who recognized four subfamilies. He is generally recognized as the father of orchid taxonomy. The next important step was taken by George Bentham with a new classification, recognizing subtribes for the first time. This classification was first presented in a paper that Bentham read to the Royal Society in 1881. Then it was published in 1883 in the final volume of Genera Plantarum. The next great contributors were Pfitzer (1887), Schlechter (1926), Mansfeld (1937), Dressler and Dodson (1960), Garay (1960, 1972), Vermeulen (1966), again Dressler (1981). and Burns-Balogh and Funk (1986). Dressler's 1993 book had considerable influence on later work.
Apostasioideae is one of the five subfamilies recognised within the orchid family, Orchidaceae. Only two genera, Neuwiedia and Apostasia, and 15 species, are recognised within the Apostasioideae in contrast to the other orchid subfamilies which are highly species rich.
The Orchidoideae, or the orchidoid orchids, are a subfamily of the orchid family (Orchidaceae) that contains around 3630 species. Species typically have a single (monandrous), fertile anther which is erect and basitonic.
Epidendroideae is a subfamily of plants in the orchid family, Orchidaceae. Epidendroideae is larger than all the other orchid subfamilies together, comprising more than 15,000 species in 576 genera. Most epidendroid orchids are tropical epiphytes, typically with pseudobulbs. There are, however, some terrestrials such as Epipactis and even a few myco-heterotrophs, which are parasitic upon mycorrhizal fungi.
Vanilloideae is one of the subfamilies of orchids belonging to the large family Orchidaceae.
Commelinaceae is a family of flowering plants. In less formal contexts, the group is referred to as the dayflower family or spiderwort family. It is one of five families in the order Commelinales and by far the largest of these with about 731 known species in 41 genera. Well known genera include Commelina (dayflowers) and Tradescantia (spiderworts). The family is diverse in both the Old World tropics and the New World tropics, with some genera present in both. The variation in morphology, especially that of the flower and inflorescence, is considered to be exceptionally high amongst the angiosperms.
Selenipedium is a genus of the orchid family (Orchidaceae). The genus has been given its own tribe, Selenipedieae, and subtribe, Selenipediinae. It is abbreviated Sel in trade journals.
Cypripedium acaule is a species of flowering plant in the orchid family Orchidaceae native to eastern North America. It is currently the provincial flower of Prince Edward Island, Canada, and the state wildflower of New Hampshire, United States.
Cypripedium parviflorum, commonly known as yellow lady's slipper or moccasin flower, is a lady's slipper orchid native to North America. It is widespread, ranging from Alaska south to Arizona and Georgia. It grows in fens, wetlands, shorelines, and damp woodlands.
The Vandeae is a large monophyletic tribe within the family of orchids.
Cypripedium reginae, known as the showy lady's slipper, pink-and-white lady's-slipper, or the queen's lady's-slipper, is a rare lady's-slipper orchid native to northern North America. Although never common, this plant has vanished from much of its historical range due to habitat loss. It is the state flower of Minnesota.
Polystachya neobenthamia is a species of flowering plants from the orchid family, Orchidaceae. It is terrestrial, lithophilic and grows among leaf litter and other detritus on rock faces. It is endemic to Tanzania.
Cypripedium calceolus is a lady's-slipper orchid, and the type species of the genus Cypripedium. It is native to Europe and Asia.
Dendrobieae is a tribe in the subfamily Epidendroideae, in the family Orchidaceae. The Dendrobieae are mostly tropical, epiphytic orchids which contain pseudobulbs.
