Acronychia Smithii
''Acronychia'' is a genus of about fifty species of plants in the rue family Rutaceae. The leaves are simple or pinnate, and the flowers bisexual with four sepals, four petals and eight stamens. They have a broad distribution including in India, Malesia, Australia and the islands of the western Pacific Ocean. About twenty species are endemic to Australia. Description Plants in the genus ''Acronychia'' are shrubs or trees with simple or trifoliate leaves arranged in opposite pairs and with oil glands in the leaves. The flowers are arranged in leaf axils either singly or in cymes or panicles. The flowers are bisexual, with four sepals, four petals and eight stamens. The petals are free from each other, as are the stamens. The stigma is small, not differentiated from the style, the fruit is a drupe and the seeds are black. Taxonomy and naming The genus ''Acronychia'' was first formally described in 1775 by Johann Reinhold Forster and Georg Forster in their book ''Characteres G ...

Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk is al ...

Plants Of The World Online
Plants of the World Online (POWO) is an online database published by the Royal Botanic Gardens, Kew. It was launched in March 2017 with the ultimate aim being "to enable users to access information on all the world's known seed-bearing plants by 2020". The initial focus was on tropical African Floras, particularly Flora Zambesiaca, Flora of West Tropical Africa and Flora of Tropical East Africa. The database uses the same taxonomical source as Kew's World Checklist of Selected Plant Families, which is the International Plant Names Index, and the World Checklist of Vascular Plants (WCVP). POWO contains 1,234,000 global plant names and 367,600 images. See also *Australian Plant Name Index *Convention on Biological Diversity *World Flora Online *Tropicos Tropicos is an online botanical database containing taxonomic information on plants, mainly from the Neotropical realm (Central, and South America). It is maintained by the Missouri Botanical Garden and was established over 25 y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salicaceae
The Salicaceae is the willow family of flowering plants. The traditional family (Salicaceae ''sensu stricto'') included the willows, poplar, aspen, and cottonwoods. Genetic studies summarized by the Angiosperm Phylogeny Group (APG) have greatly expanded the circumscription of the family to contain 56 genera and about 1220 species, including the Scyphostegiaceae and many of the former Flacourtiaceae. In the Cronquist system, the Salicaceae were assigned to their own order, Salicales, and contained three genera (''willow, Salix'', ''Populus'', and ''Chosenia''). Recognized to be closely related to the Violaceae and Passifloraceae, the family is placed by the APG in the order Malpighiales. Under the new circumscription, all members of the family are trees or shrubs that have Simple leaf, simple leaves with Phyllotaxis, alternate arrangement and temperate members are usually deciduous. Most members have serrate or dentate leaf margins, and those that have such toothed margins all e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Populus
''Populus'' is a genus of 25–30 species of deciduous flowering plants in the family Salicaceae, native to most of the Northern Hemisphere. English names variously applied to different species include poplar (), aspen, and cottonwood. The western balsam poplar ('' P. trichocarpa'') was the first tree to have its full DNA code determined by DNA sequencing, in 2006. Description The genus has a large genetic diversity, and can grow from tall, with trunks up to in diameter. The bark on young trees is smooth, white to greenish or dark gray, and often has conspicuous lenticels; on old trees, it remains smooth in some species, but becomes rough and deeply fissured in others. The shoots are stout, with (unlike in the related willows) the terminal bud present. The leaves are spirally arranged, and vary in shape from triangular to circular or (rarely) lobed, and with a long petiole; in species in the sections ''Populus'' and ''Aigeiros'', the petioles are laterally flattened, s ...

Type (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost al ...

Characteres Generum Plantarum
''Characteres generum plantarum'' (complete title , "Characteristics of the types of plants collected, described, and delineated during a voyage to islands of the South Seas, in the years 1772–1775 by Johann Reinhold Forster and Georg Forster") is a 1775/1776 book by Johann Reinhold Forster and Georg Forster about the botanical discoveries they made during the second voyage of James Cook. The book contains 78 plates, the majority of which depict dissections of flowers at natural size. The book introduced 94 binomial names from 75 genera, of which 43 are still the accepted names today. Many plant genera were named after friends or patrons of the Forsters. The book was published in a folio and a quarto edition and translated into German in 1779. It is an important book as the earliest publication of names and descriptions of the native species of New Zealand. Background Johann Reinhold Forster was the main scientific companion travelling with James Cook on his 1772–1775 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
