Contents

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. [2]

Taxonomy and discovery

This species was initially described as Phragmipedium xerophyticum by Soto Arenas, Salazar & Hágsater in 1990, but transferred to its own genus by Albert & Chase in 1992, in part based on results from DNA analysis. [2] The genus Mexipedium is listed as Phragmipedium in Appendix I of the Convention on International Trade in Endangered Species (CITES), and for other legal purposes. Allied genera include Cypripedium , Paphiopedilum , Selenipedium and Phragmipedium .

Its name is derived from the country of origin Mexico and the Latin pes (“foot”), referring to the slipper-shaped lip. The specific epithet xerophyticum is from the Greek ξηρός (xērós, "dry") and φυτόν (phutón, "plant"), referring to its preference for dry conditions.

Mexipedium xerophyticum is known from a single location in Oaxaca, Mexico. Only seven plants were observed at the time of its discovery. Mexipedium was recently rediscovered in a nearby locality. [3] A small number of plants were removed for propagation in case plant hunters eradicated the wild stock. Plants are now available as propagules.

Description and habitat

This is a lithophytic orchid, growing on cliffs, shielded from the sun, at an elevation of 320 m (1,050 ft). [3] But it grows as well on rocks or in the detritus in crevasses. Its growth form is unusual in that it tends to spread by runners, offset from the parent plant by several centimeters. The silvery-green leaves are small, stiff and semi-erect. The tiny white-pink flowers show a shieldlike, pinkish staminode and a slipper-shaped lip. The curved petals are scythe-shaped. Inflorescences are multifloral and branched.

The Pleurothallidinae are a neotropical subtribe of plants of the orchid family (Orchidaceae) including 29 genera in more than 4000 species.

Cypripedioideae Subfamily of orchids

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.

<i>Cypripedium</i> Genus of flowering plants in the orchid family Orchidaceae

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".

<i>Paphiopedilum</i> Genus of orchids

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.

<i>Aerangis</i> Genus of orchids

Aerangis, abbreviated as Aergs in horticultural trade, is a genus of the Orchid family (Orchidaceae). The name of this genus has been derived from the Greek words 'aer' (air) and 'angos' (urn), referring to the form of the lip. It is the type genus of the subtribe Aerangidinae, which has recently been subsumed in the subtribe Angraecinae. Approximately 50 species in this genus are known mostly from tropical Africa, but also from the Comoro Islands, Madagascar and Sri Lanka.

<i>Phragmipedium</i> Genus of orchids

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.

The taxonomy of the Orchidaceae 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.. 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, Vermeulen (1966), again Dressler (1981). and Burns-Balogh and Funk (1986). Dressler's 1993 book had considerable influence on later work.
