Spiranthes nebulorum is a species of orchid found in Mexico and Guatemala. [1]
Spiranthes nebulorum reach a height of 18-33cm. They have 2–5 leaves which are up to 9cm long. The leaf shape is linear-lanceolate to narrowly oblong-lanceolate. The 10-30 flowers are arranged in a dense spiral around the stem. Like all Spiranthes, each flower head has 3 sepals (with the dorsal sepal at the top) and 3 petals (with the labellum at the bottom). The sepals and petals are white to greenish white and the sepals have visible green veins.
They look similar to Spiranthes graminea , Spiranthes laciniata and Spiranthes praecox but their ranges do not overlap. [2]
Spiranthes nebulorum occurs in the southern Sierra Madre Oriental, in Oaxaca, and in Chiapas in Mexico, and in Alta Verapaz, Chimaltenango, and Huehuetenango in Guatemala.
They prefer grassy and rocky slopes as well as sphagnum bogs. They occur at elevations from 2000-3150m. [2]
Spiranthes nebulorum specimens were first collected by Lindley and labelled as Spiranthes graminea. Paul M. Catling and Vivian R. Catling described the plants as a new species in 1988. [2]
Spiranthes is a genus of orchids in the subfamily Orchidoideae. They are known commonly as ladies tresses, ladies'-tresses, or lady's tresses. The genus is distributed in the Americas, Eurasia, and Australia. The genus name Spiranthes is derived from the Greek speira ("coil") and anthos ("flower"), and was inspired by the spirally arranged inflorescence.
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.
Spiranthes romanzoffiana, commonly known as hooded lady's tresses or Irish lady's-tresses, is a species of orchid. Collected by Chamisso during the Romanzov expedition it was described by him in 1828 and named for Count Nikolay Rumyantsev who financed the expedition. This orchid is native to North America, Ireland and the British Isles.
Dudleya lanceolata is a succulent plant known by the common name lanceleaf liveforever or lance-leaved dudleya. It is an extremely variable and widely ranging species that occurs from Monterey County and Kern County in California south through Ensenada in Baja California. It is characterized by green to purple lanceolate leaves, red, orange, or less commonly yellow petals, and is typically tetraploid. Despite its diversity, it is quite stable as a species, but hybrids may be discovered with other species of Dudleya, which can make it difficult to discern in areas where numerous species converge.
Calochortus albus is a species in the genus Calochortus in the family Liliaceae. It is also known by the common names fairy lantern, white fairy lantern, pink fairy lantern, lantern of the fairies, globe lily, white globe lily, white globe-tulip, alabaster tulip, Indian bells,satin bells, snowy lily-bell, and snow drops.
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.
Cypripedium arietinum, the ram's head lady's slipper, is a rare orchid that grows in lightly shaded areas with calcareous soils. It is characteristic of the alvars around the Great Lakes in North America, as well as in New England. In Canada, it is found from Quebec to Saskatchewan, plus an isolated population in Nova Scotia, where it grows on gypsum based soils, 330 km away from the nearest population in Maine.
Petenaea cordata was first described in Elaeocarpaceae and later placed in Tiliaceae, but most authors have been uncertain about its familial affinities. It was considered a taxon incertae sedis in the Angiosperm Phylogeny Group classification. Molecular analyses based on a recent collection from Guatemala indicate a distant, weakly supported sister-group relationship to the African genus Gerrardina. As no obvious synapomorphies exist for Gerrardina and Petenaea, the new monogeneric family Petenaeaceae was proposed. The polymorphic order Huerteales now comprises four small families: Dipentodontaceae, Gerrardinaceae, Petenaeaceae and Tapisciaceae. Petenaea cordata is the only species in the genus Petenaea.
Dudleya attenuata is a species of perennial succulent plant known by the common name taper-tip liveforever, native to Baja California and a small portion of California. A rosette-forming leaf succulent, it has narrow pencil shaped leaves that can often be found covered in a white epicuticular wax. The thin, sprawling stems branch to form the clusters of rosettes, with plants creating a "clump" up to 40 cm wide. The small flowers are white or yellow, with 5 spreading petals. It is a diverse, variable species that extends from the southernmost coast of San Diego County to an area slightly north of the Vizcaino Desert, hybridizing with many other species of Dudleya in its range. Some plants with white or pinkish flowers were referred to as Orcutt's liveforever, referring to a former subspecies split on the basis of the flower color.
Corallorhiza odontorhiza, common name fall coral-root or small-flowered coral-root, is a species of orchid widespread across eastern and central United States, and reported also from Mexico, Central America, Quebec and Ontario. In North America, it occurs in forested areas up to an elevation of 2800 m.
Sagittaria graminea, the grassy arrowhead or grass-leaved arrowhead, is an aquatic plant species native to eastern North America.
Pterostylis graminea, commonly known as the grass-leaved greenhood, is a species of orchid endemic to New Zealand. It has erect, grass-like leaves with the upper ones higher than the yellowish-green and transparent white flower.
Spiranthes australis, commonly known as austral ladies tresses, is a species of orchid that grows from southern Caspian Sea and Himalayan Mountains to the South-West Pacific. It has up to about ten leaves at the base of a flowering stem with up to sixty small pink and white flowers spirally arranged around it.
Kefersteinia graminea is an orchid found in Venezuela, Colombia, and Ecuador. Euglossine bees pollinate the species.
Spiranthes lucida, the shining ladies'-tresses, is a species of orchid native to northeastern North America.
Spiranthes arcisepala, the Appalachian ladies' tresses, is a species of flowering plant in the family Orchidaceae. This orchid is native to eastern North America. Long treated as part of Spiranthes cernua the species complex was reevaluated and Spiranthes arcisepala established as a separate species in 2017.
Spiranthes casei, or Case's lady's tresses, is a species of orchid native to the northeastern United States and Canada.
Spiranthes igniorchis, or fire ladies' tresses, is a species of orchid endemic to Florida.
Spiranthes graminea or the Canelo lady's tresses is a species of orchid found in Mexico and Central America.
Spiranthes sheviakii, the old field ladies' tresses, is a species of orchid growing in North America.
