Salicaceae
The Salicaceae are the willow family of flowering plants. The traditional family (Salicaceae ''sensu stricto'') includes the willows, poplars. 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 tropical 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'' (now a synonym of ''Salix''). 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, most 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 many of those that have s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flacourtiaceae
The Flacourtiaceae is a defunct family of flowering plants whose former members have been scattered to various families, mostly to the Achariaceae and Salicaceae. It was so vaguely defined that hardly anything seemed out of place there and it became a dumping ground for odd and anomalous genera, gradually making the family even more heterogeneous. In 1975, Hermann Sleumer noted that "Flacourtiaceae as a family is a fiction; only the tribes are homogeneous." In Cronquist's classification, the Flacourtiaceae included 79–89 genera and 800–1000 species. Of these, many, including the type genus '' Flacourtia'', have now been transferred to the Salicaceae in the molecular phylogeny-based classification, known as the APG IV system, established by the Angiosperm Phylogeny Group. In the list below, the Salicaceae are circumscribed broadly. Some taxonomists further divide the Salicaceae ''sensu lato'' into three families: Salicaceae ''sensu stricto ''Sensu'' is a Latin word meanin ...

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] |
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 (Populus trichocarpa, ''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 (botany), bark on young trees is smooth and 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 (botany), petiole; in species in the sections ''Populus'' ...

Abatia
''Abatia'' (synonym (taxonomy), syn. ''Raleighia'' George Gardner (botanist), Gardner) is a genus of about ten species of Central America, Central and South American trees in the family Salicaceae (following the Angiosperm Phylogeny Group classification). Previously, it was treated in the family Flacourtiaceae, or tribe Abatieae of the family Passifloraceae (Lemke 1988) or Samydaceae by George Bentham, G. Bentham & Joseph Dalton Hooker, J.D. Hooker and John Hutchinson (botanist), Hutchinson. Its native range stretches from Mexico to northern Argentina. It is also found in Bolivia, Brazil, Colombia, Costa Rica, Ecuador, and Peru. ''Abatia'' has opposite leaves with very small stipules and marginal glands at the base of the blade of the leaf. The valvate (meeting at the edges without overlapping) perianth (sepal and petal together) members are closely joined at the base. They bear many wiktionary:Filament, filamentous processes.

Scyphostegia
''Scyphostegia borneensis'' is a species of shrub or small tree endemic to Borneo. This unusual plant is the only species in the genus ''Scyphostegia''. In many taxonomic classifications the genus was placed in its own family, the Scyphostegiaceae. Analyses of DNA data indicated that the species is related to a group of species of the now defunct Flacourtiaceae, a group which is now placed in a broadly circumscribed Salicaceae The Salicaceae are the willow family of flowering plants. The traditional family (Salicaceae ''sensu stricto'') includes the willows, poplars. Genetic studies summarized by the Angiosperm Phylogeny Group (APG) have greatly expanded the circumsc ....

Azara (plant)
''Azara'' is a genus of eleven species of flowering plants in the family Salicaceae. They are native to temperate to subtropical regions of South America, from southern Brazil and Bolivia to southern Argentina and Chile. They are most often found at woodland margins and lakesides. ''Azara'' was formerly classed in the family Flacourtiaceae. They are evergreen shrubs and small trees growing to 1–8 m tall. The leaves are alternate, or in some species they appear paired, are simple 1–9 cm long and 0.5–5 cm broad. The opposite-leaved appearance of some species is unusual in that one stipule is enlarged giving the appearance of opposite paired"leaves. The flowers are small, yellow or greenish, strongly fragrant, with a 4-5-lobed calyx and no petals but conspicuous long, often brightly colored, stamens; flowering is in spring. The fruit is a red to black berry 3–10 mm diameter. Several species are cultivated as ornamental plants in gardens. In temperate re ...

Cronquist System
The Cronquist system is a list of systems of plant taxonomy, taxonomic classification system of angiosperms, flowering plants. It was developed by Arthur Cronquist in a series of monographs and texts, including ''The Evolution and Classification of Flowering Plants'' (1968; 2nd edition, 1988) and ''An Integrated System of Classification of Flowering Plants'' (1981) (''see'' #Bibliography, Bibliography). Cronquist's system places flowering plants into two broad classes, Magnoliopsida (dicotyledons) and Liliopsida (monocotyledons). Within these classes, related orders are grouped into subclasses. While the scheme was widely used, in either the original form or in adapted versions, many botanists now use the Angiosperm Phylogeny Group classification for the orders and families of flowering plants, first developed in 1998. The system as laid out in Cronquist's ''An Integrated System of Classification of Flowering Plants'' (1981) counts 64 orders and 321 families in class Magnoliopsida a ...

Willow
Willows, also called sallows and osiers, of the genus ''Salix'', comprise around 350 species (plus numerous hybrids) of typically deciduous trees and shrubs, found primarily on moist soils in cold and temperate regions. Most species are known as willow, but some narrow-leaved shrub species are called osier, and some broader-leaved species are referred to as sallow (from Old English ''sealh'', related to the Latin word ''salix'', willow). Some willows (particularly arctic and alpine species) are low-growing or creeping shrubs; for example, the dwarf willow (''Salix herbacea'') rarely exceeds in height, though it spreads widely across the ground. Description Willows all have abundant watery bark sap, which is heavily charged with salicin, soft, usually pliant, tough wood, slender branches, and large, fibrous, often stoloniferous roots. The roots are remarkable for their toughness, size, and tenacity to live, and roots readily sprout from aerial parts of the plant. Lea ...
