Oxera
''Oxera'' is a genus of flowering plants in the family Lamiaceae native to Vanuatu and New Caledonia in the western Pacific. Description Species of ''Oxera'' show a variety of growth forms, including lianas, shrubs and trees. The leaves are simple, and are petiolate (on short stalks), except in '' O. sessilifolia'', with entire or occasionally sinuate (wavy) edges. The inflorescences are loose thyrses of flowers, growing from leaf axils (axillary) or directly from the stem (cauliflory). The flowers are large, conspicuous and bisexual; the calyx is actinomorphic (rotationally symmetrical), but the corolla is zygomorphic, sometimes strongly so. Although some species have four stamens in each flower, they are usually reduced in number with two stamens, usually the posterior pair, forming staminodes instead. Distribution Twenty of the twenty-one species are found on the island of Grande Terre (the main island of New Caledonia). Three species occur on the adjacent island of ...

Lamiaceae
The Lamiaceae ( ) or Labiatae are a family (biology), family of flowering plants commonly known as the mint, deadnettle, or sage family. Many of the plants are aromatic in all parts and include widely used culinary herbs like basil (herb), basil, mentha, mint, rosemary, Salvia officinalis, sage, savory (herb), savory, marjoram, oregano, Hyssopus officinalis, hyssop, thyme, lavender, and perilla, as well as traditional medicines such as catnip, ''Salvia'', Monarda, bee balm, Leonotis leonurus, wild dagga, and Leonurus japonicus, oriental motherwort. Some species are shrubs, trees (such as teak), or, rarely, vines. Many members of the family are widely cultivated, not only for their aromatic qualities, but also their ease of cultivation, since they are readily propagated by stem cuttings. Besides those grown for their edible leaves, some are grown for decorative foliage. Others are grown for seed, such as ''Salvia hispanica'' (chia), or for their edible tubers, such as ''Plectr ...

Maoutia
''Maoutia'' is a genus of shrubs or small trees in the nettle family (Urticaceae). It is native to Malesia and the South Pacific. It is found in Fiji, Java, Lesser Sunda Islands, Maluku, New Guinea, Philippines, Ryukyu Islands, Samoa, Society Islands, Solomon Islands, Taiwan, Tonga, Vanuatu and Wallis and Futuna Islands. The genus name of ''Maoutia'' is in honour of Emmanuel Le Maout (1799–1877), who was a French naturalist. Description The leaves are alternate. The inflorescence branches dichotomously (i.e. it repeatedly divides into two) and the flowers are arranged in small clusters. The pistillate ("female") flowers have very small petals. ''Maoutia'' species resemble those of '' Leucosyke'' and ''Debregeasia''.

Isle Of Pines (New Caledonia)
The Isle of Pines (, ; ) is an island in the Pacific Ocean, in the archipelago of New Caledonia, an overseas collectivity of France. The island is part of the commune (municipality) of L'Île-des-Pins, in the South Province of New Caledonia. The Isle of Pines is nicknamed ' ("the closest island to Paradise"). The island is around and measures by . It lies southeast of Grande Terre, New Caledonia's main island, and is southeast of the capital Nouméa. There is one airport (code ILP) with a runway. The Isle of Pines is surrounded by the New Caledonia Barrier Reef. The inhabitants of the island are mainly native Melanesian Kanaks, and the population is 2,000 (estimated 2006) (1989 population 1,465). The island is rich with animal life and is home to unusual creatures such as the crested gecko '' Correlophus ciliatus'' and the world's largest gecko, ''Rhacodactylus leachianus''. The ' is the island's highest point, at elevation. River Ouro is the longest river. His ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lifou
Lifou () is a communes of France, commune of France in the Loyalty Islands Province of New Caledonia, Pacific Ocean. Geography Lifou is made up of Lifou Island, the largest and most heavily populated of the Loyalty Islands, its smaller neighbour Tiga Island, and several uninhabited islets in between these two. All these islands lie among the Loyalty Islands, northeast of New Caledonia, New Caledonia's mainland. At , Lifou Island is the largest atoll in the world. The town of Wé, on Lifou Island, is the administrative centre of the commune of Lifou as well as the provincial seat of the Loyalty Islands Province. Climate Lifou has a tropical rainforest climate (Köppen climate classification: ''Af'') that closely borders a tropical monsoon climate (Köppen climate classification: ''Am''). The average annual temperature in Lifou is . The average annual rainfall is with March as the wettest month. The temperatures are highest on average in February, at around , and lowest in Aug ...

Loyalty Islands
Loyalty Islands Province (, ) is one of the three top-level administrative subdivisions of New Caledonia. It encompasses the Loyalty Islands () archipelago in the Pacific Ocean, located northeast of the New Caledonian mainland of Grande Terre. The provincial government seat is at Lifou. The Loyalty Islands are a '' collectivité territoriale'' of France. The province's 2019 population was approximately 18,353 inhabitants living on almost . The native inhabitants are Melanesians who speak various Kanak languages and Polynesians who speak the Fagauvea language. History The first Western contact on record is attributed to British Captain William Raven of the whaler ''Britannia'', who was on his way in 1793 from Norfolk Island to Batavia (now called Jakarta). It is very likely, however, that the discovery and name originated with officials on the London ship ''Loyalty'', which was on a Pacific Ocean trading voyage from 1789 to 1790. The French Government demanded the removal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant Cultivation
Agriculture encompasses crop and livestock production, aquaculture, and forestry for food and non-food products. Agriculture was a key factor in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in the cities. While humans started gathering grains at least 105,000 years ago, nascent farmers only began planting them around 11,500 years ago. Sheep, goats, pigs, and cattle were domesticated around 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. In the 20th century, industrial agriculture based on large-scale monocultures came to dominate agricultural output. , small farms produce about one-third of the world's food, but large farms are prevalent. The largest 1% of farms in the world are greater than and operate more than 70% of the world's farmland. Nearly 40% of agricultural land is found on farms larger than . However, five of every six farms i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Introduced Species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Staminode
In botany, a staminode is an often rudimentary, sterile or abortive stamen, which means that it does not produce pollen.Jackson, Benjamin, Daydon; ''A Glossary of Botanic Terms with their Derivation and Accent''; Published by Gerald Duckworth & Co. London, 4th ed 1928 Staminodes are frequently inconspicuous and stamen-like, usually occurring at the inner whorl of the flower, but are also sometimes long enough to protrude from the corolla. Sometimes, the staminodes are modified to produce nectar, as in the witch-hazel ''(Hamamelis)''.jin lu mei shu. Hamamelis Linnaeus, Sp. Pl. 1: 124. 1753. Flora of China 9: 32. 2003 Staminodes can be a critical characteristic for differentiating between species, for instance in the orchid genus ''Paphiopedilum'', and among the penstemons. In the case of cannas, the petals are inconsequential and the staminodes are refined into eye-catching petal-like replacements. A spectacular example of staminode is given by ''Couroupita guianensis ''C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
