Spiranthes Cernua
''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. Description ''Spiranthes cernua'' plants grow to tall. They have 1 to 5 narrow, basal, upright leaves, long and wide. The leaves are present during flowering but wilt afterwards. The white flowers are arranged in a spiral around the stem. Each flower is long and consists of 3 sepals and 3 petals, all curved forward to give the flower a long bell shape. Flowers are slightly to strongly nodding (hence the name), with older flowers usually nodding more than new ones. The dorsal sepal (the one at the top) is convex and recurved upwards towards the tip. The lip (bottom petal) curves strongly downwards towards its tip. Etymology The genus name, Spiranthes, originated from the Greek words speira (coil) and anthos (flower ...

Carl Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was the son of a curate and was born in Råshult, in the countryside of Småland, southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quebec
Quebec is Canada's List of Canadian provinces and territories by area, largest province by area.

Spiranthes Incurva
''Spiranthes incurva'', the Sphinx ladies' tresses, is a species of flowering plant in the family Orchidaceae. This orchid is native to the upper Midwest and Great Lakes Basin of North America. The species was originally described as ''Ibidium incurvum'' in 1906. Long treated as part of a ''sensu lato'' ''Spiranthes cernua'', the species complex was reevaluated and ''Spiranthes incurva'' reestablished as a separate species in 2017.

Spiranthes Casei
''Spiranthes casei'', or Case's lady's tresses, is a species of orchid native to the northeastern United States and Canada. Description ''Spiranthes casei'' plants are 7–44 cm tall.

Spiranthes Arcisepala
''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. Description ''Spiranthes arcisepala'' is a terrestrial, perennial, deciduous herb. Like many other spiranthes orchids, it is acaulescent with one to four basal leaves persisting through anthesis (flowering). Flowers are arranged in a spike forming a spiral around the central stem with the plant reaching a height of up to . Like all orchids the flowers have three petals and three sepals. The petals and sepals are both white and roughly long and, except for the lower petal or lip, less than wide. The flowers look very similar to ''Spiranthes incurva'' but the lateral sepals are bent downward with their tips often lower than the tip of the lip. This feature also giv ...

Cryptic Species
In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each other, further blurring any distinctions. Terms that are sometimes used synonymously but have more precise meanings are cryptic species for two or more species hidden under one species name, sibling species for two (or more) species that are each other's closest relative, and species flock for a group of closely related species that live in the same habitat. As informal taxonomic ranks, species group, species aggregate, macrospecies, and superspecies are also in use. Two or more taxa that were once considered conspecific (of the same species) may later be subdivided into infraspecific taxa (taxa within a species, such as plant varieties), which may be a complex ranking but it is not a species complex. In most cases, a species complex is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bumblebees
A bumblebee (or bumble bee, bumble-bee, or humble-bee) is any of over 250 species in the genus ''Bombus'', part of Apidae, one of the bee families. This genus is the only Extant taxon, extant group in the tribe Bombini, though a few extinct related genera (e.g., ''Calyptapis'') are known from fossils. They are found primarily in the Northern Hemisphere, although they are also found in South America, where a few lowland tropical species have been identified. European bumblebees have also been introduced to New Zealand and Tasmania. Female bumblebees can sting repeatedly, but generally ignore humans and other animals. Most bumblebees are eusociality, social insects that form colony (biology), colonies with a single queen. The colonies are smaller than those of honey bees, growing to as few as 50 individuals in a nest. Psithyrus, Cuckoo bumblebees are brood parasite, brood parasitic and do not make nests or form colonies; their queens aggressively invade the nests of other bumble ...

Sphagnum
''Sphagnum'' is a genus of approximately 380 accepted species of mosses, commonly known as sphagnum moss, also bog moss and quacker moss (although that term is also sometimes used for peat). Accumulations of ''Sphagnum'' can store water, since both living and dead plants can hold large quantities of water inside their cells; plants may hold 16 to 26 times as much water as their dry weight, depending on the species.Bold, H. C. 1967. Morphology of Plants. second ed. Harper and Row, New York. p. 225–229. The empty cells help retain water in drier conditions. As ''Sphagnum'' moss grows, it can slowly spread into drier conditions, forming larger mires, both raised bogs and blanket bogs. Thus, ''Sphagnum'' can influence the composition of such habitats, with some describing ''Sphagnum'' as 'habitat manipulators' or 'autogenic ecosystem engineers'. These peat accumulations then provide habitat for a wide array of peatland plants, including sedges and Calcifuge, ericaceous shrubs, as ...
