Pandanus Balfourii
''Pandanus balfourii'', also known as , is a species of plant in the family Pandanaceae, one of four '' Pandanus'' species that are endemic to the Seychelles. Description ''Pandanus balfourii'' is a small, slender, elegant tree of about 8 meters in height, with small supporting roots, and bearing its drooping leaves in spiral rosettes. Its medium-sized fruit-body (25 cm) hangs from the stem and contain 70-90 individual fruits. Distribution and habitat It is endemic to Seychelles, and was especially common on all the granitic islands. It was formerly extremely common along the coast, and its local name refers to this habitat preference. However, it has been known to live in more rocky areas at higher altitudes too. It is threatened by habitat loss. Other indigenous '' Pandanus'' of the Seychelles include '' Pandanus sechellarum'', '' Pandanus hornei'' and '' Pandanus multispicatus''.

Plant
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the ...

Pandanaceae
Pandanaceae is a family of flowering plants native to the tropics and subtropics of the Old World, from West Africa through the Pacific. It contains 982 known species in five genera, of which the type genus, ''Pandanus'', is the most important, with species like ''Pandanus amaryllifolius'' and karuka (''Pandanus julianettii'') being important sources of food. The family likely originated during the Late Cretaceous. Characteristics Pandanaceae includes trees, shrubs, lianas, vines, epiphytes, and perennial herbs. Stems may be simple or bifurcately branched, and may have aerial prop roots. The stems bear prominent leaf scars. The leaves are very long and narrow, sheathing, simple, undivided, with parallel veins; the leaf margins and abaxial midribs are often prickly. The plants are dioecious. The inflorescences are terminally borne racemes, spikes or umbels, with subtended spathes, which may be brightly colored. The flowers are minute and lack perianths. Male flowers contain nu ...

Pandanus
''Pandanus'' is a genus of monocots with some 750 accepted species. They are palm-like, dioecious trees and shrubs native to the Old World tropics and subtropics. The greatest number of species are found in Madagascar and Malaysia. Common names include pandan, screw palm, and screw pine. They are classified in the order Pandanales, family Pandanaceae. Description Often called pandanus palms, these plants are not closely related to palm trees. The species vary in size from small shrubs less than tall, to medium-sized trees tall, typically with a broad canopy, heavy fruit, and moderate growth rate. The trunk is stout, wide-branching, and ringed with many leaf scars. Mature plants can have branches. Depending on the species, the trunk can be smooth, rough, or warty. The roots form a pyramidal tract to hold the trunk. They commonly have many thick stilt roots near the base, which provide support as the tree grows top-heavy with leaves, fruit, and branches. These roots are adven ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seychelles
Seychelles (, ; ), officially the Republic of Seychelles (french: link=no, République des Seychelles; Creole: ''La Repiblik Sesel''), is an archipelagic state consisting of 115 islands in the Indian Ocean. Its capital and largest city, Victoria, is east of mainland Africa. Nearby island countries and territories include the Comoros, Madagascar, Mauritius, and the French overseas departments of Mayotte and Réunion to the south; and Maldives and the Chagos Archipelago (administered by the United Kingdom as the British Indian Ocean Territory) to the east. It is the least populated sovereign African country, with an estimated 2020 population of 98,462. Seychelles was uninhabited prior to being encountered by Europeans in the 16th century. It faced competing French and British interests until coming under full British control in the late 18th century. Since proclaiming independence from the United Kingdom in 1976, it has developed from a largely agricultural society to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pandanus Sechellarum
''Pandanus sechellarum'' ("Vakwa maron") is a species of plant in the family Pandanaceae. It is one of five species of ''Pandanus'' that are endemic to Seychelles. Description This large species (up to 15 meters in height) has extremely large and prominent stilt-roots, that grow individually and far apart, from high up on the trunk. Its medium-sized (30 cm), spherical fruit-body contains about 70 individual fruit segments, and hangs from the stem on a stalk. Distribution and habitat ''Pandanus sechellarum'' was formerly one of the most common species in the indigenous vegetation of the Seychelles, to which it is endemic. Currently it is usually found on steep terrain, river valleys or in accessible mountain tops. Other indigenous ''Pandanus'' of the Seychelles include ''Pandanus balfourii'', '' Pandanus hornei'' and '' Pandanus multispicatus''. The Madagascan species ''Pandanus utilis ''Pandanus utilis'', the common screwpine is, despite its name, a monocot and not a ...

Pandanus Hornei
''Pandanus hornei'' (''Vakwa Parasol'', or ''Vacoa Parasol'') is a species of plant in the Pandan, or Screwpine family (Pandanaceae), one of several ''Pandanus'' species that are endemic to the Seychelles. Description This species is a tall (15 meters, or 49 feet), erect tree. It has a single, tall, straight trunk, with a spreading, parasol-like canopy only near the top. Its branches usually divide into groups of three. Its stilt-roots are characteristically large but very closely packed.

Pandanus Multispicatus
''Pandanus multispicatus'' (Vakwa de Montanny) is a species of plant in the family Pandanaceae, one of several ''Pandanus'' species that are endemic to the Seychelles. Description This is the only ''Pandanus'' of Seychelles that does not become a tree, but rather grows as a low (max 4 meters high), sprawling shrub, the thin stems often lying decumbent along the ground. The fruit bodies resemble corn cobs. Each contains 200-400 individual fruit segments, and several fruit bodies are born together on a stalk. Distribution and habitat It grows mainly in rocky areas and was previously very common in the higher mountains of Seychelles (the reason for its local name, "Vakwa de Montanny"). Formerly widespread, it is currently restricted to only eight small and isolated populations. Other indigenous ''Pandanus'' of the Seychelles include ''Pandanus sechellarum'', ''Pandanus hornei'' and ''Pandanus balfourii''.

Pandanus Utilis
''Pandanus utilis'', the common screwpine is, despite its name, a monocot and not a pine. It is native to Madagascar and naturalised in Mauritius and the Seychelles. Description The trunk features aerial prop roots. The leaves are linear and spiny, with a spiral arrangement on the tree. The leaves are also dried out and rolled, and used to make mats in Kerala, India; and Hawaii. Care must be taken when handling the leaves because of their sharp spines. The fruit of ''Pandanus utilis'' is edible, although not flavorful to humans and must be cooked prior to consumption. It attracts mammals such as, in North America, squirrels. Introduction Within the family Pandanaceae, the genus ''Pandanus'' is thought to compose the largest group of plants.M. H. Zimmerman, et al., "Vascular Construction and Development in the Stems of Certain Pandanaceae," ''Botanical Journal of the Linnean Society'' 68:1 (January 1974): 21-41 It is estimated that there are somewhere between 500 and 1,000 sp ...

Flora Of Seychelles
The Wildlife of Seychelles comprises the flora and fauna of the Seychelles islands off the eastern coast of Africa in the western Indian Ocean. Human history and fauna In common with many fragile island ecosystems, the early human history of Seychelles saw the loss of biodiversity including the disappearance of most of the giant tortoises from the granitic islands, felling of coastal and mid-level forests and extinction of species such as the Marianne white-eye, Seychelles parakeet, Seychelles black terrapin, and the saltwater crocodile. However, extinctions were far fewer than on other islands such as Mauritius or Hawaii, partly due to a shorter period of human occupation (since 1770). The Seychelles today is known for success stories in protecting its flora and fauna. Arguably the first scientific study of Seychelles was that of the Marion Dufresne expedition in 1768, two years prior to settlement. Dufresne instructed Duchemin, captain of the vessel La Digue, to ...''especia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
