Pometia (plant)
''Pometia'' is a genus of 2 species of rainforest trees, constituting part of the plant family Sapindaceae. Description They are large trees, which are monoecious, usually with buttress roots, with red exudate (substance like resin, pouring out of the trunk) when cut. The leaves are paripinnate, arranged alternate, sessile (without stalk). The leaflets are usually in many pairs, with the first pair (near base) small, like stipules, others evidently larger, usually serrate. The leaves have many lateral veins, extending to tips of dentate margins and parallel. The thyrses (flower on the branch) is terminal (at the end) or axillary (on a leaf joint). The flowers are unisexual and actinomorphic (radially symmetrical). The calyx is cupular (cup shaped). The sepals are half connate and valvate. It has 5 petals, usually broadly obovate or subtriangular, without scales or with 1 gland adaxially. The (flower) disk is annular and 5-lobed. It has 5 stamens (or male flowers) which are long e ...

Johann Reinhold Forster
Johann Reinhold Forster (22 October 1729 – 9 December 1798) was a German Continental Reformed church, Reformed (Calvinist) pastor and natural history, naturalist of partially Scottish descent who made contributions to the early ornithology of Europe and North America. He is best known as the naturalist on James Cook's Second voyage of James Cook, second Pacific voyage, where he was accompanied by his son Georg Forster. These expeditions promoted the career of Johann Reinhold Forster and the findings became the bedrock of colonial professionalism and helped set the stage for the future development of anthropology and ethnology. They also laid the framework for general concern about the impact that alteration of the physical environment for European economic expansion would have on exotic societies. Biography Forster's family originated in the Lord Forrester, Lords Forrester in Scotland from where his great-grandfather had emigrated after losing most of his property during the ...

Flora Of Indo-China
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous (ecology), indigenous) native plant, native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms ''gut flora'' or ''skin flora''. Etymology The word "flora" comes from the Latin name of Flora (mythology), Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Sri Lanka
Wildlife of Sri Lanka includes its flora and fauna and their natural habitats. Sri Lanka has one of the highest rates of biological endemism (16% of the fauna and 23% of flowering plants are endemic) in the world. Ecological zones The mountains and the southwestern part of the country, known as the "wet zone," receive ample rainfall (an annual average of 2500 millimeters). Most of the southeast, east, and northern parts of the country comprise the "dry zone, which receives between 1200 and 1900 mm of rain annually. Forestry in Sri Lanka Faunal diversity Number of described species of fauna in Sri Lanka The most recent update on the Sri Lankan biodiversity released during the 6th National Report of the Convention on Biological Diversity. This report provided an updated list of species up to the end of December 2018. However, in 2019, 54 new species were described: including 26 spiders, (14 cellar spiders, 7 jumping spiders, 4 crab spiders and one tarantula species), ...

Flora Of Taiwan
The Flora of Taiwan () is the flora of the country of Taiwan, also known as the Republic of China.''Flora of Taiwan'' also refers to a set of books recording the vascular plants of Taiwan (territories). The second edition consists of six volumes published in 1993–2003 and is available on-line. Taiwan is an island of diverse geography and varied climates, allowing for a vast array of flora to be present. Situated between China and the Philippine Sea basin, it is said to be the home of approximately 4000 species of vascular plants. Of these plants, it is estimated that 600 are ferns, 28 are gymnosperms, 2400 are dicots, and 1000 are monocots. The island can also be divided up into seven different floristic regions: northeastern, central, Hengchun, Lanyu (Orchid Island) and Lutao (Green Island), Alpine, upper montaine and supalpine, and lower montane and lowland. The northeastern region of Taiwan receives much more rainfall and cloud coverage than other regions, making the specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of China
The flora of China consists of a diverse range of plant species including over 39,000 vascular plants, 27,000 species of fungi and 3000 species of bryophytes.Wu, Z. Y., P. H. Raven & D. Y. Hong, eds. 2006. Flora of China. Vol. 22 (Poaceae). Science Press, Beijing, and Missouri Botanical Garden Press, St. Louis More than 30,000 plant species are native to China, representing nearly one-eighth of the world's total plant species, including thousands found nowhere else on Earth. China's land, extending over 9.6 million km, contains a variety of ecosystems and climates for plants to grow in. Some of the main climates include shores, tropical and subtropical forests, deserts, elevated plateaus and mountains. The events of the continental drift and early Paleozoic Caledonian movement also play a part in creating climatic and geographical diversity resulting in high levels of endemic vascular flora. These landscapes provide different ecosystems and climates for plants to grow in, creati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants Described In 1776
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 ability ...

Sapindaceae Genera
The Sapindaceae are a family of flowering plants in the order Sapindales known as the soapberry family. It contains 138 genera and 1858 accepted species. Examples include horse chestnut, maples, ackee and lychee. The Sapindaceae occur in temperate to tropical regions, many in laurel forest habitat, throughout the world. Many are laticiferous, i.e. they contain latex, a milky sap, and many contain mildly toxic saponins with soap-like qualities in either the foliage and/or the seeds, or roots. The largest genera are ''Serjania'', '' Paullinia'', ''Allophylus'' and '' Acer''. Description Plants of this family have a variety of habits, from trees to herbaceous plants to lianas. The leaves of the tropical genera are usually spirally alternate, while those of the temperate maples ('' Acer), Aesculus'', and a few other genera are opposite. They are most often pinnately compound, but are palmately compound in ''Aesculus'', and simply palmate in ''Acer''. The petiole has a swollen b ...

Seasonal Tropical Forest
Seasonal tropical forest, also known as moist deciduous, semi-evergreen seasonal, tropical mixed or monsoon forests, typically contain a range of tree species: only some of which drop some or all of their leaves during the dry season. This tropical forest is classified under the Walter system as (i) tropical climate with high overall rainfall (typically in the 1000–2500 mm range; 39–98 inches) and (ii) having a very distinct wet season with (an often cooler “winter”) dry season. These forests represent a range of habitats influenced by monsoon (Am) or tropical wet savannah (Aw) climates (as in the Köppen climate classification). Drier forests in the Aw climate zone are typically deciduous and placed in the Tropical dry forest biome: with further transitional zones (ecotones) of savannah woodland then tropical and subtropical grasslands, savannas, and shrublands. Distribution Seasonal (mixed) tropical forests can be found in many parts of the tropical zone, wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rainforests
Rainforests are characterized by a closed and continuous tree canopy, moisture-dependent vegetation, the presence of epiphytes and lianas and the absence of wildfire. Rainforest can be classified as tropical rainforest or temperate rainforest, but other types have been described. Estimates vary from 40% to 75% of all biotic species being indigenous to the rainforests. There may be many millions of species of plants, insects and microorganisms still undiscovered in tropical rainforests. Tropical rainforests have been called the "jewels of the Earth" and the " world's largest pharmacy", because over one quarter of natural medicines have been discovered there. Rainforests as well as endemic rainforest species are rapidly disappearing due to deforestation, the resulting habitat loss and pollution of the atmosphere. Definition Rainforest are characterized by a closed and continuous tree canopy, high humidity, the presence of moisture-dependent vegetation, a moist layer of leaf ...

Marquesas Islands
The Marquesas Islands (; french: Îles Marquises or ' or '; Marquesan: ' ( North Marquesan) and ' ( South Marquesan), both meaning "the land of men") are a group of volcanic islands in French Polynesia, an overseas collectivity of France in the southern Pacific Ocean. Their highest point is the peak of Mount Oave (french: Mont Oave, links=no) on Ua Pou island, at 1,230 m (4,035 ft) above sea level. Archaeological research suggests the islands were colonized in the 10th century AD by voyagers from West Polynesia. Over the centuries that followed, the islands have maintained a "remarkably uniform culture, biology and language". The Marquesas were named after the 16th century Spanish Viceroy of Peru, the Marquis of Cañete ( es, Marqués de Cañete, italic=unset) by navigator , who visited them in 1595. The Marquesas Islands constitute one of the five administrative divisions (') of French Polynesia. The capital of the Marquesas Islands' administrative subdivision is t ...
