Salicaceae Genera
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 (''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 leaves with alternate arrangement and temperate members are usually deciduous. Most members have serrate or dentate leaf margins, and those that have such toothed margins all exhibit salicoid teeth; a salicoi ...

Salix Alba
''Salix alba'', the white willow, is a species of willow native to Europe and western and central Asia.Meikle, R. D. (1984). ''Willows and Poplars of Great Britain and Ireland''. BSBI Handbook No. 4. .Rushforth, K. (1999). ''Trees of Britain and Europe''. Collins . The name derives from the white tone to the undersides of the leaves. It is a medium-sized to large deciduous tree growing up to 10–30 m tall, with a trunk up to 1 m diameter and an irregular, often-leaning crown. The bark is grey-brown, and deeply fissured in older trees. The shoots in the typical species are grey-brown to green-brown. The leaves are paler than most other willows, due to a covering of very fine, silky white hairs, in particular on the underside; they are 5–10 cm long and 0.5–1.5 cm wide. The flowers are produced in catkins in early spring, and pollinated by insects. It is dioecious, with male and female catkins on separate trees; the male catkins are 4–5 cm long, t ...

Phyllotaxis
In botany, phyllotaxis () or phyllotaxy is the arrangement of leaf, leaves on a plant stem. Phyllotactic spirals form a distinctive class of patterns in nature. Leaf arrangement The basic leaf#Arrangement on the stem, arrangements of leaves on a stem are opposite and alternate (also known as spiral). Leaves may also be Whorl (botany), whorled if several leaves arise, or appear to arise, from the same level (at the same Node (botany), node) on a stem. With an opposite leaf arrangement, two leaves arise from the stem at the same level (at the same Node (botany), node), on opposite sides of the stem. An opposite leaf pair can be thought of as a whorl of two leaves. With an alternate (spiral) pattern, each leaf arises at a different point (node) on the stem. Distichous phyllotaxis, also called "two-ranked leaf arrangement" is a special case of either opposite or alternate leaf arrangement where the leaves on a stem are arranged in two vertical columns on opposite sides of t ...

Calantica (plant)
''Calantica'' is a genus of flowering plants in the family Salicaceae. It contains 10 species of shrubs and trees endemic to Madagascar, seven of which are threatened. ''Calantica'' is closely related to the pantropical and diverse genus ''Homalium'', from which it differs in having a superior ovary, instead of a semi-inferior ovary. The genus is also similar to ''Bivinia'' in its superior ovary but has numerous stamens and long spiciform inflorescences.

Aphaerema
''Aphaerema'' was formerly a genus of flowering plants in the Flacourtiaceae, consisting of one species of small shrubs, ''Aphaerema spicata'', which is native to Brazil and Argentina. Later studies indicated that ''Aphaerema'' should be classified in the willow family, Salicaceae, and combined with the genus ''Abatia''.Alford, M.H. 2006. Nomenclatural innovations in neotropical Salicaceae. ''Novon'' 16(3): 293–298. Unfortunately, because the name ''Abatia spicata'' was already used, the species was given the new name ''Abatia angeliana ''Abatia'' (synonym (taxonomy), syn.

Abatia
''Abatia'' (syn. ''Raleighia'' Gardner) is a genus of about ten species of 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 G. Bentham & J.D. Hooker and 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 filamentous processes. The leaves of '' A. rugosa'' and '' A. parviflora'' are source of black dye in Peru. The genus name of ''Abatia'' is in honour of Pedro Abad y Mestre (1747–1800), a Spanish apothecary and profes ...

Ovule
In seed plants, the ovule is the structure that gives rise to and contains the female reproductive cells. It consists of three parts: the ''integument'', forming its outer layer, the ''nucellus'' (or remnant of the megasporangium), and the female gametophyte (formed from a haploid megaspore) in its center. The female gametophyte — specifically termed a ''megagametophyte''— is also called the ''embryo sac'' in angiosperms. The megagametophyte produces an egg cell for the purpose of fertilization. The ovule is a small structure present in the ovary. It is attached to the placenta by a stalk called a funicle. The funicle provides nourishment to the ovule. Location within the plant In flowering plants, the ovule is located inside the portion of the flower called the gynoecium. The ovary of the gynoecium produces one or more ovules and ultimately becomes the fruit wall. Ovules are attached to the placenta in the ovary through a stalk-like structure known as a ''funiculus'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gynoecium
Gynoecium (; ) is most commonly used as a collective term for the parts of a flower that produce ovules and ultimately develop into the fruit and seeds. The gynoecium is the innermost whorl of a flower; it consists of (one or more) ''pistils'' and is typically surrounded by the pollen-producing reproductive organs, the stamens, collectively called the androecium. The gynoecium is often referred to as the "female" portion of the flower, although rather than directly producing female gametes (i.e. egg cells), the gynoecium produces megaspores, each of which develops into a female gametophyte which then produces egg cells. The term gynoecium is also used by botanists to refer to a cluster of archegonia and any associated modified leaves or stems present on a gametophyte shoot in mosses, liverworts, and hornworts. The corresponding terms for the male parts of those plants are clusters of antheridia within the androecium. Flowers that bear a gynoecium but no stamens are called ''pi ...
