Acacia
''Acacia'', commonly known as the wattles or acacias, is a large genus of shrubs and trees in the subfamily Mimosoideae of the pea family Fabaceae. Initially, it comprised a group of plant species native to Africa and Australasia. The genus name is New Latin, borrowed from the Greek (), a term used by Dioscorides for a preparation extracted from the leaves and fruit pods of ''Vachellia nilotica'', the original type of the genus. In his ''Pinax'' (1623), Gaspard Bauhin mentioned the Greek from Dioscorides as the origin of the Latin name. In the early 2000s it had become evident that the genus as it stood was not monophyletic and that several divergent lineages needed to be placed in separate genera. It turned out that one lineage comprising over 900 species mainly native to Australia, New Guinea, and Indonesia was not closely related to the much smaller group of African lineage that contained ''A. nilotica''—the type species. This meant that the Australasian lineage (by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Acacia Species
Several Cladistics, cladistic analyses have shown that the genus ''Acacia sensu lato, Acacia'' is not monophyletic. While the subg. ''Acacia'' and subg. ''Phyllodinae'' are monophyletic, subg. ''Aculeiferum'' is not. This subgenus consists of three clades. Therefore, the following list of ''Acacia'' species cannot be maintained as a single entity, and must either be split up, or broadened to include species previously not in the genus. This genus has been provisionally divided into 5 genus, genera, ''Acacia'', ''Vachellia'', ''Senegalia'', ''Acaciella'' and ''Mariosousa''. The proposed type species of ''Acacia'' is ''Acacia penninervis''. Which of these segregate genera is to retain the name ''Acacia'' has been controversial. The genus was previously typified with the African species ''Acacia scorpioides'' (L.) W.F.Wright, a synonym of ''Acacia nilotica'' (L.) Delile. Under the original typification, the name ''Acacia'' would stay with the group of species currently recognized ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vachellia Nilotica
''Vachellia nilotica'', more commonly known as ''Acacia nilotica'', and by the vernacular names of gum arabic tree, babul, thorn mimosa, Egyptian acacia or thorny acacia, is a flowering tree in the family Fabaceae. It is native to Africa, the Middle East and the Indian subcontinent. It is also considered a ' weed of national significance' and an invasive species of concern in Australia, as well as a noxious weed by the federal government of the United States. Taxonomy This species of tree is the type species of the Linnaean genus ''Acacia'', which derives its name from grc, ἀκακία, ', the name given by early Greek botanist-physician Pedanius Dioscorides (ca. 40–90) to this tree as a medicinal, in his book '' Materia Medica''. The genus ''Acacia'' was long known not to be taxonomically monophyletic, and despite being the type species of that genus, ''A. nilotica'' has since been moved to the genus ''Vachellia'', with the genus name ''Acacia'' being reserved for Australia ...

Vachellia
''Vachellia'' is a genus of flowering plants in the legume family, Fabaceae, commonly known as thorn trees or acacias. It belongs to the subfamily Mimosoideae. Its species were considered members of genus ''Acacia'' until 2009. ''Vachellia'' can be distinguished from other acacias by its capitate inflorescences and spinescent stipules. Before discovery of the New World, Europeans in the Mediterranean region were familiar with several species of ''Vachellia'', which they knew as sources of medicine, and had names for them that they inherited from the Greeks and Romans. The wide-ranging genus occurs in a variety of open, tropical to subtropical habitats, and is locally dominant. In parts of Africa, ''Vachellia'' species are shaped progressively by grazing animals of increasing size and height, such as gazelle, gerenuk, and giraffe. The genus in Africa has thus developed thorns in defence against such herbivory. Nomenclature By 2005, taxonomists had decided that ''Acacia sensu lato' ...

Acacia Penninervis (5368395701)
''Acacia penninervis'', commonly known as mountain hickory wattle, or blackwood, is a perennial shrub or tree is an ''Acacia'' belonging to subgenus ''Phyllodineae'', that is native to eastern Australia. Description The shrub or tree typically grows to a height of and has an erect to spreading habit. It has finely or deeply fissured bark that is usually a dark grey colour. The glabrous branchlets are more or less terete and occasionally covered in a fine white powdery coating. Like most species of ''Acacia'' it has phyllodes rather than true leaves. The glabrous and evergreen phyllodes have a narrowly oblanceolate or narrowly elliptic shape and are straight to slightly curved with a length of and a width of with a prominent midvein and marginal veins and are finely penniveined. The plant blooms throughout the year producing pale yellow flowers.

Mimosoideae
The Mimosoideae are a traditional subfamily of trees, herbs, lianas, and shrubs in the pea family (Fabaceae) that mostly grow in tropical and subtropical climates. They are typically characterized by having radially symmetric flowers, with petals that are twice divided (valvate) in bud and with numerous showy, prominent stamens. Recent work on phylogenetic relationships has found that the Mimosoideae form a clade nested with subfamily Caesalpinioideae and the most recent classification by ''The Legume Phylogeny Working Group'' refer to them as the Mimosoid clade within subfamily Caesalpinioideae. The group includes about 40 genera and 2,500 species. Taxonomy Some classification systems, for example the Cronquist system, treat the Fabaceae in a narrow sense, raising the Mimisoideae to the rank of family as Mimosaceae. The Angiosperm Phylogeny Group treats Fabaceae in the broad sense. The Mimosoideae were historically subdivided into four tribes (Acacieae, Ingeae, Mimoseae, and Mi ...

Senegalia
''Senegalia'' (from Senegal and ''Acacia senegal'' (L.) Willd.) is a genus of flowering plants in the family Fabaceae. It belongs to the Mimosoid clade. Until 2005, its species were considered members of ''Acacia.'' The genus was considered polyphyletic and required further division, with the genera '' Parasenegalia'' and ''Pseudosenegalia'' accepted soon after. ''Senegalia'' can be distinguished from other acacias by its spicate inflorescences and non-spinescent stipules. Plants in the genus are native to the tropical and subtropical areas of the world, occurring on the Australian, Asian, African and South and North American continents, as well as in Wallacea. Species list ''Senegalia'' comprises the following 222 species, as of February 2021: *'' Senegalia adenocalyx'' *''Senegalia albizioides'' — climbing wattle *'' Senegalia alemquerensis'' *'' Senegalia alexae'' *''Senegalia altiscandens'' *'' Senegalia amazonica'' *''Senegalia andamanica'' *'' Senegalia angust ...

Acaciella
''Acaciella'' is a Neotropical genus of flowering plants in the legume family, Fabaceae, and its subfamily Mimosoideae. Its centre of diversity is along the Mexican Pacific coast. They are unarmed, have no extrafloral nectaries and the polyads of their pollen are 8-celled. Though its numerous free stamens (sometimes >300) is typical of '' Acacia s.l.'', it has several characteristics in common with genus ''Piptadenia'' (tribe Mimoseae). Its pollen and free amino acids resemble that of ''Senegalia''. Molecular studies place it sister to a monophyletic clade comprising elements of genus ''Acacia'', and the tribe Ingeae. A nectary ring is present between the stamens and ovary, in common with ''Acacia'' subg. ''Aculeiferum''. Species *''Acaciella angustissima'' (Mill.)

Leslie Pedley
Leslie Pedley (19 May 1930 – 27 November 2018)IPNILeslie Pedley/ref> was an Australian botanist who specialised in the genus ''Acacia''. He is notable for bringing into use the generic name ''Racosperma'', creating a split in the genus, which required some 900 Australian species to be renamed, because the type species of ''Acacia'', ''Acacia nilotica'', now ''Vachellia nilotica'', had a different lineage from the Australian wattles. However, the International Botanical Congress (IBC), held in Melbourne in 2011, ratified its earlier decision to retain the name ''Acacia'' for the Australian species, but to rename the African species. See also: ''Acacia'' and ''Vachellia nilotica'' regarding the dispute, anAPNIfor a brief history of the name, ''Racosperma''. In 2018, Japanese botanists Hiroyoshi Ohashi and Kazuaki K.

Petiole (botany)
In botany, the petiole () is the stalk that attaches the leaf blade to the stem, and is able to twist the leaf to face the sun. This gives a characteristic foliage arrangement to the plant. Outgrowths appearing on each side of the petiole in some species are called stipules. Leaves with a petiole are said to be petiolate, while leaves lacking a petiole are called sessile or apetiolate. Description The petiole is a stalk that attaches a leaf to the plant stem. In petiolate leaves, the leaf stalk may be long, as in the leaves of celery and rhubarb, or short. When completely absent, the blade attaches directly to the stem and is said to be sessile. Subpetiolate leaves have an extremely short petiole, and may appear sessile. The broomrape family Orobanchaceae is an example of a family in which the leaves are always sessile. In some other plant groups, such as the speedwell genus '' Veronica'', petiolate and sessile leaves may occur in different species. In the grasses (Poaceae), ...
