Prayer Plant
Prayer plant may refer to: *Marantaceae, commonly called "prayer plants", since their leaves raise at the evening and look as if they're praying **''Calathea'', a genus of the above family that are called "prayer plants" **''Goeppertia'', a genus where many species of ''Calathea'' have been reassigned **''Maranta leuconeura ''Maranta leuconeura'', also known as prayer plant, is a species of flowering plant in the family Marantaceae, native to the Brazilian tropical forests. It is a variable, rhizomatous perennial, growing to tall and broad, with crowded clumps of ...

Marantaceae
The Marantaceae are a family, the arrowroot family, of flowering plants consisting of 31 genera and around 530 species, defining it as one of the most species-rich families in its order.Kennedy, H. (2000). “Diversification in pollination mechanisms in the Marantaceae”. Pp. 335-343 in Monocots: systematics and evolution, eds. K. L. Wilson and D. A. Morrison. Melbourne: CSIROLey, A. C., and Claßen-Bockhoff, R. (2011). “Evolution in African Marantaceae - evidence from phylogenetic, ecological and morphological studies”. Syst. Bot. 36, 277–290. doi: 10.1600/036364411X569480 Species of this family are found in lowland tropical forests of Africa, Asia, and the Americas. The majority (80%) of the species are found in the American tropics, followed by Asian (11%) and African (9%) tropics. They are commonly called the prayer-plant family and are also known for their unique secondary pollination presentation. Description The plants usually have underground rhizomes or tubers. The ...

Nyctinasty
Nyctinasty is the circadian rhythmic nastic movement of higher plants in response to the onset of darkness, or a plant "sleeping". Nyctinastic movements are associated with diurnal light and temperature changes and controlled by the circadian clock. It has been argued that for plants that display foliar nyctinasty, it is a crucial mechanism for survival; however, most plants do not exhibit any nyctinastic movements. Nyctinasty is found in a range of plant species and across xeric, mesic, and aquatic environments, suggesting that this singular behavior may serve a variety of evolutionary benefits. Examples are the closing of the petals of a flower at dusk and the sleep movements of the leaves of many legumes. Physiology Plants use phytochrome to detect red and far red light. Depending on which kind of light is absorbed, the protein can switch between a Pr state that absorbs red light and a Pfr state that absorbs far red light. Red light converts Pr to Pfr and far red light convert ...

Praying
Prayer is an invocation or act that seeks to activate a rapport with an object of worship through deliberate communication. In the narrow sense, the term refers to an act of supplication or intercession directed towards a deity or a deified ancestor. More generally, prayer can also have the purpose of thanksgiving or praise, and in comparative religion is closely associated with more abstract forms of meditation and with charms or spells. Prayer can take a variety of forms: it can be part of a set liturgy or ritual, and it can be performed alone or in groups. Prayer may take the form of a hymn, incantation, formal creedal statement, or a spontaneous utterance in the praying person. The act of prayer is attested in written sources as early as 5000 years ago. Today, most major religions involve prayer in one way or another; some ritualize the act, requiring a strict sequence of actions or placing a restriction on who is permitted to pray, while others teach that prayer may be p ...

Calathea
''Calathea'' is a genus of flowering plants belonging to the family Marantaceae. They are commonly called calatheas or (like their relatives) prayer plants. About 200 species formerly assigned to ''Calathea'' are now in the genus ''Goeppertia''. Calathea currently contains around 60 species. Native to the tropical Americas, many of the species are popular as pot plants due to their decorative leaves and, in some species, colorful inflorescences. The young leaves and bracts can retain pools of water called phytotelmata, that provide habitat for many invertebrates.Jalinsky, J., T.A. Radocy, R. Wertenberger, & C.S. Chaboo. 2014. Insect diversity in phytotelmata habitats of two host plants, Heliconia stricta Huber (Heliconiaceae) and Calathea lutea Schult (Marantaceae) in the south-east Amazon of Peru. Journal of the Kansas Entomological Society 87(3): 299–311. Description Foliage Calathea leaves are often large and colorfully patterned. The leaves are often variegated with brig ...

Goeppertia
''Goeppertia'' is a genus of flowering plants in the family Marantaceae, native to the New World Tropics. It contains 243 accepted species, many of which were until recently assigned to ''Calathea''. It was first described by Nees von Esenbeck in 1831, who erroneously erected another genus ''Goeppertia'' in 1836, which has now been synonymized with ''Endlicheria''. In 1862 August Grisebach described another genus ''Goeppertia''; this has now been synonymized with '' Bisgoeppertia''. The genus name of ''Goeppertia'' is in honour of Heinrich Göppert (1800–1884), a German botanist and paleontologist. Species The following species are accepted: *'' Goeppertia ackermannii'' (Körn.) Borchs. & S.Suárez *'' Goeppertia acuminata'' (Steyerm.) Borchs. & S.Suárez *'' Goeppertia aemula'' (Körn.) Borchs. & S.Suárez *''Goeppertia affinis'' (Fenzl ex Regel) Borchs. & S.Suárez *'' Goeppertia albertii'' (L.H.Bailey & Raffill) Borchs. & S.Suárez *'' Goeppertia albovaginata'' (K.Koch & ...
