Drypetes
''Drypetes'' is a plant genus of the family Putranjivaceae, in the order Malpighiales. It was previously in the family Euphorbiaceae, tribe Drypeteae, and was the sole pantropical zoochorous genus of the family. The genus comprises about 200 species, found in Africa, southern Asia, Australia, Central America, the Caribbean, southern Florida, Mexico, and various oceanic islands. They are dioecious trees or shrubs. Along with ''Putranjiva'', also in the Putranjivaceae, ''Drypetes'' contains the only plants outside the Brassicales known to contain mustard oils.

Drypetes Deplanchei
''Drypetes deplanchei'' is a tree of eastern and northern Australia. It also occurs in New Caledonia and Lord Howe Island. The genus is derived from the Greek, ''dryppa'' meaning "olive fruit".

Drypeteae
Putranjivaceae is a rosid family that is composed of 218 species in 2 genera of evergreen tropical trees that are found mainly in the Old World tropics, but with a few species in tropical America. Members of this family have 2-ranked coriaceous leaves, which, if fresh, typically have a radish-like or peppery taste. The flowers are fasciculate and usually small, and the fruits of these species are a single-seeded drupe crown by the persistent stigmas. This family has its origin in Africa and Malesia. It is the only family outside Brassicales that produces mustard oils. Taxonomy This family was formerly a tribe (Drypeteae) of the subfamily Phyllanthoideae in the Euphorbiaceae. When the Phyllanthoideae was separated to form the new family Phyllanthaceae Phyllanthaceae is a Family (biology), family of flowering plants in the eudicot Order (biology), order Malpighiales. It is most closely related to the family Picrodendraceae.Kenneth J. Wurdack and Charles C. Davis. 2009. "Ma ... [...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] |
Euphorbiaceae
Euphorbiaceae (), the spurge family, is a large family of flowering plants. In English, they are also commonly called euphorbias, which is also the name of Euphorbia, the type genus of the family. Most spurges, such as ''Euphorbia paralias'', are herbaceous plant, herbs, but some, especially in the tropics, are shrubs or trees, such as ''Hevea brasiliensis''. Some, such as ''Euphorbia canariensis'', are succulent and resemble cactus, cacti because of convergent evolution. This family has a Cosmopolitan distribution, cosmopolitan global distribution. The greatest diversity of species is in the tropics; however, the Euphorbiaceae also have many species in nontropical areas of all continents except Antarctica. Description The Leaf, leaves are alternate, seldom opposite, with stipules. They are mainly simple, but where compound, are always palmate, never pinnate. Stipules may be reduced to trichome#Plant trichomes, hairs, glands, or spine (botany), spines, or in succulent specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malpighiales
The Malpighiales comprise one of the largest Order (biology), orders of flowering plants. The order is very diverse, with well-known members including willows, Viola (plant), violets, aspens and Populus, poplars, Euphorbia pulcherrima, poinsettia, Rafflesia arnoldii, corpse flower, Coca, coca plant, Manihot esculenta, cassava, Linum usitatissimum, flaxseed, Ricinus communis, castor bean, Hypericum perforatum, Saint John's wort, Passiflora edulis, passionfruit, Garcinia mangostana, mangosteen, and Hippomane mancinella, manchineel tree. The order is not part of any of the Systematics, classification systems based only on plant morphology and the relationships of its diverse members can be hard to recognize except with molecular phylogenetic evidence. Molecular clock calculations estimate the origin of stem group Malpighiales at around 100 million years ago (mya (unit), Mya) and the origin of crown group Malpighiales at about 90 Mya. The Malpighiales contain about 36 families and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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 ...

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 ...

William Hemsley (botanist)
William Botting Hemsley (29 December 1843, in East Hoathly – 7 October 1924, in Kent) was an English botanist and 1909 Victoria Medal of Honour recipient. He was born in East Hoathly, Sussex and in 1860 started work at the Royal Botanic Gardens, Kew as an Improver, then Assistant for India in the Herbarium, finally Keeper of Herbarium and Library. He wrote a number of botanical works. In 1888, a genus of flowering plants from south-east Asia, belonging to the family Cucurbitaceae was named '' Hemsleya'' in his honour. He was elected a Fellow of the Royal Society Fellowship of the Royal Society (FRS, ForMemRS and HonFRS) is an award granted by the Fellows of the Royal Society of London to individuals who have made a "substantial contribution to the improvement of natural science, natural knowledge, incl ... in June 1889.
