Pandanus Barkleyi
''Pandanus barkleyi'' is a species of plant in the family Pandanaceae, endemic to Mauritius. Description This is an extremely variable and difficult to identify species. Overall in its shape and growth form, this species can sometimes resemble the related '' Pandanus glaucocephalus''. ''Pandanus barkleyi'' is typically a short (4-5m) tree, with ascending branches. The 10–18 cm wide trunk is grey, fissured, and bears only a few stilt-roots near the base of the stem. The leaves are slender and dark green, with a translucent light-yellow midrib. New leaves are initially erect, but they later droop, and eventually the old dead leaves persist hanging around the stem, beneath the dense rosette. The leaf margins are lined with very tiny yellow-green spines, but these are usually not near the leaf base. This species has variable 9–18 cm, globose fruit-head that becomes greenish-brown to purple when ripe. Each fruit-head holds an extremely variable number (50-150) of drup ...

Isaac Bayley Balfour
Sir Isaac Bayley Balfour, Knight Commander of the Order of the British Empire, KBE, Fellow of the Royal Society, FRS, Fellow of the Royal Society of Edinburgh, FRSE (31 March 1853 – 30 November 1922) was a Scottish botanist. He was Regius Professor of Botany (Glasgow), Regius Professor of Botany at the University of Glasgow from 1879 to 1885, Sherardian Professor of Botany at the University of Oxford from 1884 to 1888, and Professor of Botany at the University of Edinburgh from 1888 to 1922. Early life He was the son of John Hutton Balfour, also a botanist, and Marion Spottiswood Bayley, and was born at home, 27 Inverleith Row, Edinburgh. His mother was granddaughter of George Husband Baird. He was the cousin of Sir James Crichton-Browne. Biography Balfour was educated at the Edinburgh Academy from 1864 to 1870. At this early stage his interests and abilities were in the biological sciences, which were taught to him by his father. Due to his father's post as Professor of Bota ...

Plant
Plants are the eukaryotes that form the Kingdom (biology), kingdom Plantae; they are predominantly Photosynthesis, photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll. Exceptions are parasitic plants that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Most plants are multicellular organism, multicellular, except for some green algae. Historically, as in Aristotle's biology, the plant kingdom encompassed all living things that were not animals, and included algae and fungi. Definitions have narrowed since then; current definitions exclude fungi and some of the algae. By the definition used in this article, plants form the clade Viridiplantae (green plants), which consists of the green algae and the embryophytes or land plants (hornworts, liverworts ...

Pandanaceae
Pandanaceae is a family of flowering plants native to the tropics and subtropics of the Old World, from West Africa to 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 numero ...

Mauritius
Mauritius, officially the Republic of Mauritius, is an island country in the Indian Ocean, about off the southeastern coast of East Africa, east of Madagascar. It includes the main island (also called Mauritius), as well as Rodrigues, Agaléga, and St. Brandon (Cargados Carajos shoals). The islands of Mauritius and Rodrigues, along with nearby Réunion (a French overseas department), are part of the Mascarene Islands. The main island of Mauritius, where the population is concentrated, hosts the capital and largest city, Port Louis. The country spans and has an exclusive economic zone covering approximately . The 1502 Portuguese Cantino planisphere has led some historians to speculate that Arab sailors were the first to discover the uninhabited island around 975, naming it ''Dina Arobi''. Called ''Ilha do Cirne'' or ''Ilha do Cerne'' on early Portuguese maps, the island was visited by Portuguese sailors in 1507. A Dutch fleet, under the command of Admiral Van War ...

Pandanus Glaucocephalus
''Pandanus glaucocephalus'' is a species of plant in the family Pandanaceae, endemic to Mauritius. Description A low (6-8m), branching tree. The 20 cm-wide trunk is grey, and bears only a few stilt-roots (or none at all), near the base of the stem. The leaves are slender and pale green. Leaf margins are lined with very tiny pale, yellow-brown spines. The leaf midrib also has spines, but not near the base. In its shape and growth form, this species most resembles the related ''Pandanus barkleyi''. This species is most easily distinguished by its 17–20 cm, globose, glaucous, blue-grey fruit-head. This is born on a short, fat stem, with long, slender, leaf-like bracts that extend further than the fruit-head. Each fruit-head holds 35-45 compressed or irregularly angled drupes. The drupes' exposed parts are raised and conical, with flattened or depressed tips, covered in cracks and scattered stigmas. Habitat The Pandanus glaucocephalus is endemic to Mauritius M ...

Endemism
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Pandanus
''Pandanus'' is a genus of monocots with about 578 accepted species. They are palm-like, dioecious trees and shrubs native to the Old World tropics and subtropics. Common names include pandan, screw palm and screw pine. The genus is classified in the order Pandanales, family Pandanaceae, and is the largest in the family. Description 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 adventitious and often branched. The top of the plant has one or more crowns of strap-shaped leaves that may be s ...
