 "Eunomia" is a genus of flowering plants, within the family Brassicaceae, subfamily Brassicoideae.
 The genus is collectively known as the stonecresses.
 They originate from sunny limestone mountainsides in Europe and West Asia, especially Turkey.
Phragmipedium is a genus of the Orchid family (Orchidaceae) (Subfamily Cypripedioideae) 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" (referring to the pouch).
 It is abbreviated 'Phrag' in trade journals.
Cryptostylis, commonly known as the tongue orchid, is a genus of flowering plants from the orchid family, Orchidaceae.
 It was first defined by the prolific Scottish botanist, Robert Brown in 1810.
 The type species has since been designated as "Cryptostylis erecta".
 Other species include "Cryptostylis hunteriana" and "Cryptostylis subulata".
 Molecular study of their DNA shows the genus lies within the tribe Diurideae within the orchid family, having previously considered part of the Cranichideae.
 Together with the genus "Coilochilus" (endemic to New Caledonia), they make up the subtribe Cryptostylidinae.
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.
 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.
 "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 (Pérez-García, 2010).
Phragmipedium besseae (Pronunciation:fraig-mi-PEE-dee-um BESS-ee-ay) is an orchid species of the genus Phragmipedium.

Caladenia longicauda" subsp.
 "extrema, commonly known as the late white spider orchid or Seaton Ross spider orchid is a plant in the orchid family Orchidaceae and is endemic to the south-west of Western Australia.
 It has a single hairy leaf and one or two mainly white flowers with long, mostly spreading lateral sepals and petals.
 It is a relatively rare orchid which is similar to the tangled white spider orchid (subspecies "redacta") but has larger flowers and a later flowering period.
Caladenia richardsiorum, commonly known as the little dip spider orchid, Richards' spider orchid or robe spider orchid, is a plant in the orchid family Orchidaceae and is endemic to South Australia.
 It is a ground orchid with a single erect, hairy leaf and usually only one yellowish-green flower.
 It is similar to the endangered Mellblom's spider orchid ("Caladenia hastata") but has a much larger leaf and the petals lack glandular tips.
Caladenia venusta, commonly known as the graceful spider orchid, large white spider orchid, or simply white spider orchid is a plant in the orchid family Orchidaceae and is endemic to southern Australia.
 It is a ground orchid with a single leaf and one or two white to cream-coloured flowers with drooping, brown, thread-like tips.
Phragmipedium caudatum, commonly called the Mandarin Orchid, is a species of orchid occurring from Peru to Bolivia.
 It is the type species of the genus "Phragmipedium".
