Pandanus Rigidifolius
''Pandanus rigidifolius'' is a species of plant in the family Pandanaceae, endemic to Mauritius. Description A low, small, spreading, many-branched tree. It produces many stilt-like roots, along the trunk, but also along the length of the side branches. It can be distinguished by its compact (often trifarious) rosettes of small, rigid, erect, red-spined, deep blue-green leaves. These are usually only 75 cm long and 6 cm wide, folded lengthwise (reduplicate), stiff, erect, and have an abrupt, obtuse leaf tip. The reddish spines are closely set along the margins of the leaves. The small (7–8 cm) fruit head is held erect on a short peduncle, and it is enclosed in three-ranked (trifarious) bracts. Each fruit head is packed with 200–220 small, unilocular drupes, with slightly convex tips. In its appearance, it is most similar to the other dwarf Mauritian species '' Pandanus microcarpus'' as well as the Madagascan species '' Pandanus microcephalus''. Another Maur ...

Reginald Edward Vaughan
Reginald Edward Vaughan OBE FRIC (27 October 1895 – 29 April 1987) was a British botanist who lived and worked in Mauritius from 1923. Biography Vaughan was born in Wooburn, Buckinghamshire, 27 October 1895, the son of Herbert and Jane Vaughan, who lived at Dell House, Wooburn. He went to Imperial College where he was awarded a second class degree in Chemistry in 1920. In 1916, at the age of 20, he enlisted in the Royal Engineers as a Pioneer and served until he was discharged, September 1918, when he was appointed Temporary Second Lieutenant in the Royal Garrison Artillery. He first worked at Harper Adams College but in 1923 he moved to Mauritius where he worked as a chemistry teacher at the Royal College Curepipe. His interest in botany developed and from 1934 he collaborated with Paul Octave Wiehe on botanical exploration and conservative, seeing the creation of 16 nature reserves between 1951 and 1974, and in 1959 the creation of the Mauritius Herbarium.

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 ...

Mauritius
Mauritius ( ; french: Maurice, link=no ; mfe, label=Mauritian Creole, Moris ), officially the Republic of Mauritius, is an island nation in the Indian Ocean about off the southeast coast of the African continent, east of Madagascar. It includes the main island (also called Mauritius), as well as Rodrigues, Agaléga and St. Brandon. 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 most of the population is concentrated, hosts the capital and largest city, Port Louis. The country spans and has an exclusive economic zone covering . Arab sailors were the first to discover the uninhabited island, around 975, and they called it ''Dina Arobi''. The earliest discovery was in 1507 by Portuguese sailors, who otherwise took little interest in the islands. The Dutch took possession in 1598, establishing a succession of short-lived settlements over a period of about ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pandanus Rigidifolius - Fruit Body 1
''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 advent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bract
In botany, a bract is a modified or specialized leaf, especially one associated with a reproductive structure such as a flower, inflorescence axis or cone scale. Bracts are usually different from foliage leaves. They may be smaller, larger, or of a different color, shape, or texture. Typically, they also look different from the parts of the flower, such as the petals or sepals. A plant having bracts is referred to as bracteate or bracteolate, while one that lacks them is referred to as ebracteate and ebracteolate, without bracts. Variants Some bracts are brightly-coloured and serve the function of attracting pollinators, either together with the perianth or instead of it. Examples of this type of bract include those of ''Euphorbia pulcherrima'' (poinsettia) and ''Bougainvillea'': both of these have large colourful bracts surrounding much smaller, less colourful flowers. In grasses, each floret (flower) is enclosed in a pair of papery bracts, called the lemma (lower bract) and p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pandanus Microcarpus
''Pandanus microcarpus'' is a species of plant in the family Pandanaceae, endemic to Mauritius. Description This small (5-6m), slender, freely branching tree can be distinguished from its closest relatives by its drooping, dark yellow-green leaves with red marginal spines. It can also easily be distinguished by its small (7–9 cm), oval, red to purple fruit-head, which is born on a twisted, recurved stalk. Each fruit-head is packed with 75-200 2.5 cm-long drupes. The exposed top of each drupe is flat or slightly convex (not forming a domed or pyramid shape). Unusually for its genus, it sometimes bears staminodes. Habitat It is endemic to Mauritius, where it was once widespread. Its habitat is now largely destroyed. Its natural habitats are rivers and swamp A swamp is a forested wetland.Keddy, P.A. 2010. Wetland Ecology: Principles and Conservation (2nd edition). Cambridge University Press, Cambridge, UK. 497 p. Swamps are considered to be transition zones because b ...

Madagascar
Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Africa across the Mozambique Channel. At Madagascar is the world's List of island countries, second-largest island country, after Indonesia. The nation is home to around 30 million inhabitants and consists of the island of Geography of Madagascar, Madagascar (the List of islands by area, fourth-largest island in the world), along with numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 90 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of wildlife of Madagascar, its wildlife is endemic. Human settlement of Madagascar occurred during or befo ...

Pandanus Drupaceus
''Pandanus drupaceus'' is a species of plant in the family Pandanaceae, endemic to Mauritius. Description A low-lying, spreading, freely-branching tree. Decumbent branches can lie along the ground and root to form new trees. There are only a few stilt-roots at the base of the trunk, and the pale grey bark is cracked and fissured. It can easily be distinguished from related species by its rosettes of wide, flat, stiff, incurved leaves. These have reddish-orange marginal spines only near the tip of the leaf, and not near the leaf base. (''Pandanus rigidifolius'' is the only other local species of ''Pandanus'' to have rigid, incurved leaves but it is a smaller decumbent species and its leaves are smaller and replicate.) The large (20–25 cm) fruit-head is held erect on a short peduncle. Each fruit-head is packed with 20-30 purple, flattened, angular drupes.Vaughan, R.E. and Wiehe, P.O. 1953.
