Proteaceae
The Proteaceae form a family (biology), family of flowering plants predominantly distributed in the Southern Hemisphere. The family comprises 83 genus, genera with about 1,660 known species. Australia and South Africa have the greatest concentrations of diversity. Together with the Platanaceae (plane trees), Nelumbonaceae (the sacred lotus) and in the recent APG IV system the Sabiaceae, they make up the order Proteales. Well-known Proteaceae genera include ''Protea'', ''Banksia'', ''Embothrium'', ''Grevillea'', ''Hakea'', and ''Macadamia''. Species such as the New South Wales waratah (''Telopea speciosissima''), king protea (''Protea cynaroides''), and various species of ''Banksia'', ''Grevillea'', and ''Leucadendron'' are popular cut flowers. The nuts of ''Macadamia integrifolia'' are widely grown commercially and consumed, as are those of ''Gevuina avellana'' on a smaller scale. Etymology The name Proteaceae was adapted by Robert Brown (botanist, born 1773), Robert Brown from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Louis-Marie Aubert Du Petit-Thouars
Louis-Marie Aubert du Petit-Thouars (5 November 1758, Saint-Martin-de-la-Place, Bournois – 12 May 1831, Paris) was a French botanist known for his work collecting and describing orchids from the three islands of Madagascar, Mauritius and Réunion. Introduction Petit-Thouars came from an aristocratic family of the region of Duchy of Anjou, Anjou, where he grew up in the castle of Boumois, near Saumur. In 1792, after an imprisonment of two years during the French Revolution, he was exiled to Madagascar and the nearby islands such as La Réunion (then called Bourbon). He started collecting many plant specimens on Madagascar, Mauritius and La Réunion. Ten years later he was able to return to France with a collection of about 2000 plants. Most of his collection went to the ''Muséum de Paris'', while some species ended up at Royal_Botanic_Gardens,_Kew , Kew. He was elected member of the prestigious ''Académie des Sciences'' on 10 April 1820. Du Petit-Thouars is remembered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cenarrhenes
''Cenarrhenes'' is a Monotypic taxon, monytypic genus in the family Proteaceae containing the single species ''Cenarrhenes nitida'', known as the Port Arthur plum or native plum. ''Cenarrhenes nitida'' is an evergreen shrub to small tree endemic to the rainforests and scrublands of western Tasmania. It bears white flowers in late spring followed by the development of fleshy fruit. Taxonomy and naming The French naturalist and explorer Jacques Labillardière described ''Cenarrhenes nitida'' in 1805, from a location described as ''in capite Van Diemen'' (Tasmania). It still bears its common name today. The genus name is derived from the Ancient Greek words ''kenos'' 'empty' and ''arrhen'' 'male', referring to the four staminode-like hypogynous glands. The genus only contains one species (monotypic taxon, monotypic). The specific epithet is the Latin adjective ''nitida'' 'bright, shining', referring to its glossy leaves. Although it resembles the persoonias in appearance, it does ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beaupreopsis
''Beaupreopsis'' is a genus of flowering plants in the family Proteaceae, with just one species in the genus, ''Beaupreopsis paniculata''. It is native to New Caledonia on the south of Grand Terre. Its habitat is shrubland at altitudes from , on substrates of eroded ultramafic rocks. Description The plants are shrubs, rarely exceeding 1.50 m in height, with thick branches, scattered and few. They have pseudo-whorled leaves (5-10 x 0, 20-0, 60 cm), more or less toothed or lobed at the apex, cuneate at the base, leathery, venation slightly prominent, petiole short and robust. Flowers are small, white or pinkish in terminal panicles from 20 to 50 cm. The fruits are small and hairy, containing a single seed. Taxonomy This plant was first described as ''Cenarrhenes paniculata'' in 1865 by French botanists Adolphe-Théodore Brongniart and Jean Antoine Arthur Gris, and published in ''Bulletin de la Société Botanique de France''. In 1968 the species was reviewed by anoth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proteoideae
Proteoideae is one of the five subfamilies of the plant family Proteaceae. The greatest diversity of the subfamily is in Africa, but there are also many species in Flora of Australia, Australia. A few species occur in South America, New Caledonia, and elsewhere. Taxonomy Proteoideae was essentially defined by Robert Brown (botanist, born 1773), Robert Brown in his 1810 ''On the natural order of plants called Proteaceae''. Brown divided Proteaceae into two "sections" based on whether or not the fruits were dehiscence (botany), dehiscent or indehiscenct. He also noted that Brown's two "sections" corresponded closely with what are now recognised as the two largest Proteaceae subfamilies, Proteoideae and Grevilleoideae, and both the indehiscence of Proteoideae and the paired flowers of Grevilleoideae are still recognised as key diagnostic characters. Brown did not publish names for his two sections, and it would not be until 1836 that the name Proteoideae would be published by Amos Ea ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Madagascar
Madagascar, officially the Republic of Madagascar, is an island country that includes the island of Madagascar and numerous smaller peripheral islands. Lying off the southeastern coast of Africa, it is the world's List of islands by area, fourth largest island, the List of island countries, second-largest island country, and the List of countries and dependencies by area, 46th largest country overall. Its capital and List of cities in Madagascar, largest city is Antananarivo. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from Africa during the Early Jurassic period, around 180 million years ago, and separated from the Indian subcontinent approximately 90 million years ago. This isolation allowed native plants and animals to evolve in relative seclusion; as a result, Madagascar is a biodiversity hotspot and one of the world's 17 megadiverse countries, with over 90% of its wildlife of Madagascar, wildlife being endemic. The island has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
