Platanthera purpurascens, the purple petal bog orchid, is a terrestrial orchid of North America. [1]
Platanthera purpurascens plants are 24–80 cm tall. Flowering time is from July to August. Flowers are green to yellowish-green with a lip that can be reddish (leading to the common name). The lip is 4-8 mm long and flowers have a short nectar spur which is 2–3 mm long. [2]
Platanthera purpurascens is endemic to the United States, occurring in Arizona, California, Colorado, New Mexico and Wyoming. Plants grow at an elevation of 2500–3300 m. They require wet habitat including seeps, stream banks and meadows. [1]
Platanthera purpurascens was first described by Per Axel Rydberg in 1901 as Limnorchis purpurascens but later assumed to be the same species or a variation of Platanthera hyperborea or Platanthera stricta. In 1997 it was again described as a separate species, Platanthera purpurascens. [3]
Platanthera praeclara, known as the western prairie fringed orchid and the Great Plains white fringed orchid, is a rare and threatened species of orchid native to North America.
Coilostylis is a genus of orchids. It was split off from the "supergenus" Epidendrum in 2004 although the Kew currently does not recognize this genus. This genus features pseudobulbs, large bracts around the flowers, and flowers that are typically resupinate, with the trilobate lip adnate to the column and having a long thin midlobe. It is not unusual for this genus to produce keikes.
Coeloglossum is a genus of flowering plants in the orchid family Orchidaceae. It has long been considered to have only one species, Coeloglossum viride, the frog orchid. Some recent classifications regard Coeloglossum as part of the larger genus, Dactylorhiza, so that C. viride becomes Dactylorhiza viridis. Other sources continue to keep Coeloglossum viride separate.
The genus Platanthera belongs to the subfamily Orchidoideae of the family Orchidaceae, and comprises about 150 species of orchids. The members of this genus, known as the butterfly orchids or fringed orchids, were previously included in the genus Orchis, which is a close relative. They are distributed throughout the temperate regions of the Northern Hemisphere. They are terrestrial and have tubercules.
Platanthera chlorantha, commonly known as greater butterfly-orchid, is a species of orchid in the genus Platanthera. It can be found throughout Europe and Morocco. The name Platanthera is derived from Greek, meaning "broad anthers", while the species name, chlorantha, means "green-flowered".
Platanthera blephariglottis, commonly known as the white fringed orchid or white-fringed orchis, is a species of orchid of the genus Platanthera. It is considered to be an endangered species in Connecticut and Ohio, a threatened species in Florida, Maryland and Rhode Island, exploitably vulnerable in New York, and susceptible to be threatened in Québec.
Platanthera elegans is a species of orchid known by several common names, including elegant piperia, coast piperia, hillside rein orchid, and hillside bogorchid. This is a showy flowering plant native to western North America. It grows from a caudex tuber and sends up a thick stem just under a meter in maximum height. The stem is topped with a cylindrical spike inflorescence of densely packed flowers with curving white to greenish-yellow petals. Coastal individuals are noticeably thicker and have more flowers than those that grow further inland; it is uncertain if these are variants, subspecies, or even separate species. They are both currently treated as P. elegans. Other species of Plantanthera, notably the endangered species P. yadonii are quite similar in appearance to some populations of this species.
Goodyera pubescens, the downy rattlesnake plantain, is one of the most common orchids native to eastern North America. It is found from Florida to Nova Scotia, west to eastern Oklahoma, Minnesota and Ontario.
Epidendrum rigidum is an epiphytic reed-stemmed Epidendrum orchid common throughout the Neotropical lowlands, below 600 m (2,000 ft).
Platanthera psycodes, commonly called lesser purple fringed orchid or small purple-fringed orchid, is a species of orchid, genus Platanthera, occurring from eastern Canada to the east-central and northeastern United States. It is imperiled in Illinois, Tennessee, North Carolina, and Kentucky.
Spiranthes cernua, commonly called nodding lady's tresses, or nodding ladies' tresses, is a species of orchid occurring from Maritime Canada to the eastern and southern United States. As the common name suggests cernua means "nodding", or "bowed" in Latin.
Platanthera flava, the palegreen orchid, is a species of pale-flowered orchid. It is native to eastern North America, from Texas east to Florida, north to Ontario, Quebec and Nova Scotia.
Isotria verticillata, commonly known as the large whorled pogonia and purple fiveleaf orchid, is an orchid species native to eastern North America.
Cypripedium yatabeanum, known as the spotted lady slipper or palomino lady's slipper, is a species of terrestrial orchid. It is native to Alaska, to the Russian Far East, and northern Japan.
Platanthera dilatata, known as tall white bog orchid, bog candle, or boreal bog orchid is a species of orchid, a flowering plant in the family Orchidaceae, native to North America. It was first formally described in 1813 by Frederick Traugott Pursh as Orchis dilatata.
