Amaryllis
''Amaryllis'' () is the only genus in the subtribe Amaryllidinae (tribe Amaryllideae). It is a small genus of flowering bulbs, with two species. The better known of the two, ''Amaryllis belladonna'', is a native of the Western Cape region of South Africa, particularly the rocky southwest area between the Olifants River Valley and Knysna. For many years there was confusion among botanists over the generic names ''Amaryllis'' and ''Hippeastrum'', one result of which is that the common name "amaryllis" is mainly used for cultivars of the genus ''Hippeastrum'', widely sold in the winter months for their ability to bloom indoors. Plants of the genus ''Amaryllis'' are known as belladonna lily, Jersey lily, naked lady, amarillo, Easter lily in Southern Australia or, in South Africa, March lily due to its propensity to flower around March. This is one of numerous genera with the common name "lily" due to their flower shape and growth habit. However, they are only distantly related ...

Hippeastrum
''Hippeastrum'' () is a genus of about 90 species and over 600 hybrids and cultivars of perennial herbaceous bulbous plants. They generally have large fleshy bulbs and tall broad leaves, generally evergreen, and large red or purple flowers. ''Hippeastrum'' is a genus in the family Amaryllidaceae (subfamily Amaryllidoideae, tribe Hippeastreae, and subtribe Hippeastrineae). The name ''Hippeastrum'', given to it by William Herbert, means "knight's star", although precisely what Herbert meant by the name is not certain. For many years there was confusion among botanists over the generic names ''Amaryllis'' and ''Hippeastrum'', one result of which is that the common name amaryllis is mainly used for cultivars of this genus, often sold as indoor flowering bulbs particularly at Christmas in the northern hemisphere. By contrast the generic name ''Amaryllis'' applies to bulbs from South Africa, usually grown outdoors. The genus is native to tropical and subtropical regions of the A ...

Amaryllis Belladonna
''Amaryllis belladonna'', the Jersey lily, belladonna-lily, naked-lady-lily, or March lily, is a plant species native to Cape Province in South Africa but widely cultivated as an ornamental. It is reportedly naturalized in many places: Corsica, Portugal, the Azores, Madeira, the Canary Islands, the Scilly Isles of Great Britain, the Democratic Republic of the Congo, Ascension Island, Australia, New Zealand, Mexico, Cuba, Haiti, the Dominican Republic, Chile, California, Texas, Louisiana, Mississippi, and the Juan Fernández Islands. Description Perennial bulbous geophyte with one to two erect solid stems which appear in late summer. The inflorescence bears 2–12 showy fragrant funnel-shaped flowers on a 'naked' (leafless) stem, which gives it the common name of naked-lady-lily. The pink flowers which may be up to 10cm in length, appear in the autumn before the leaves (hysteranthy) which are narrow and strap shaped.

Amaryllideae
Amaryllideae are a tribe of subfamily Amaryllidoideae (family Amaryllidaceae). They are herbaceous monocot perennial flowering plants with a predominantly Southern African distribution, with the exception of the pantropical genus ''Crinum''. They are generally treated as consisting of four subtribes. In addition to ''Crinum'', other genera include ''Amaryllis'', ''Boophone'' and ''Strumaria''. Taxonomy Phylogeny The placement of Amaryllideae within subfamily Amaryllidoideae is shown in the following cladogram: Subdivision There are four subtribes: * Amaryllidinae Pax * Boophoninae D.Müll.-Doblies & U.Müll.-Doblies * Crininae Baker * Strumariinae Traub ex D.Müll.-Doblies & U.Müll.-DobliesBot.

Bulb
In botany, a bulb is structurally a short stem with fleshy leaves or leaf basesBell, A.D. 1997. ''Plant form: an illustrated guide to flowering plant morphology''. Oxford University Press, Oxford, U.K. that function as food storage organs during dormancy. (In gardening, plants with other kinds of storage organ are also called "ornamental bulbous plants" or just "bulbs".) Description The bulb's leaf bases, also known as scales, generally do not support leaves, but contain food reserves to enable the plant to survive adverse conditions. At the center of the bulb is a vegetative growing point or an unexpanded flowering shoot. The base is formed by a reduced stem, and plant growth occurs from this basal plate. Roots emerge from the underside of the base, and new stems and leaves from the upper side. Tunicate bulbs have dry, membranous outer scales that protect the continuous lamina of fleshy scales. Species in the genera ''Allium'', ''Hippeastrum'', '' Narcissus'', and ''Tulipa' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant Symbolism
Various folk cultures and traditions assign symbolic meanings to plants. Although these are no longer commonly understood by populations that are increasingly divorced from their rural traditions, some meanings survive. In addition, these meanings are alluded to in older pictures, songs and writings. New symbols have also arisen: one of the most known in the United Kingdom is the red poppy as a symbol of remembrance of the fallen in war. See also * Birth flower * Language of flowers * Plants in culture * Hanakotoba * Floral emblem In a number of countries, plants have been chosen as symbols to represent specific geographic areas. Some countries have a country-wide floral emblem; others in addition have symbols representing subdivisions. Different processes have been used to ...

Stamen
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains ''sporangium, microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in ''Canna (plant), Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea'' ...

Stigma (botany)
The stigma () is the receptive tip of a carpel, or of several fused carpels, in the gynoecium of a flower. Description The stigma, together with the style and ovary (typically called the stigma-style-ovary system) comprises the pistil, which is part of the gynoecium or female reproductive organ of a plant. The stigma itself forms the distal portion of the style, or stylodia, and is composed of , the cells of which are receptive to pollen. These may be restricted to the apex of the style or, especially in wind pollinated species, cover a wide surface. The stigma receives pollen and it is on the stigma that the pollen grain germinates. Often sticky, the stigma is adapted in various ways to catch and trap pollen with various hairs, flaps, or sculpturings. The pollen may be captured from the air (wind-borne pollen, anemophily), from visiting insects or other animals ( biotic pollination), or in rare cases from surrounding water (hydrophily). Stigma can vary from long and sle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Connation
Connation in plants is the developmental fusion of organs of the same type, for example, petals to one another to form a tubular corolla. This is in contrast to adnation, the fusion of dissimilar organs. Such organs are described as connate or adnate, respectively. When like organs that are usually well separated are placed next to each other, but not actually connected, they are described as connivent (that is the case for anthers in several genera, such as ''Solanum''). Terms for connation of flower parts *Synsepalous: All the sepals of a flower are fused into a cup or tube; the fused portion is the calyx tube, and any non fused tips are the calyx lobes. *Sympetalous: All the petals of a flower are fused into a cup, tube, or other shape. *Stamens: **Synandrous: Stamens are fused in an unspecified manner **Synfilamentous: Stamens are fused by their filaments **Synantherous: Stamens are fused by their anthers *Syncarpous: Carpels are fused together to form a compound ovary Th ...

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] |
Tepal
A tepal is one of the outer parts of a flower (collectively the perianth). The term is used when these parts cannot easily be classified as either sepals or petals. This may be because the parts of the perianth are undifferentiated (i.e. of very similar appearance), as in ''Magnolia'', or because, although it is possible to distinguish an outer whorl of sepals from an inner whorl of petals, the sepals and petals have similar appearance to one another (as in ''Lilium''). The term was first proposed by Augustin Pyramus de Candolle in 1827 and was constructed by analogy with the terms "petal" and "sepal". (De Candolle used the term ''perigonium'' or ''perigone'' for the tepals collectively; today, this term is used as a synonym for ''perianth''.) p. 39. Origin Undifferentiated tepals are believed to be the ancestral condition in flowering plants. For example, '' Amborella'', which is thought to have separated earliest in the evolution of flowering plants, has flowers with undiffer ...

Floral Symmetry
Floral symmetry describes whether, and how, a flower, in particular its perianth, can be divided into two or more identical or mirror-image parts. Uncommonly, flowers may have no axis of symmetry at all, typically because their parts are spirally arranged. Actinomorphic Most flowers are actinomorphic ("star shaped", "radial"), meaning they can be divided into 3 or more identical sectors which are related to each other by rotation about the center of the flower. Typically, each sector might contain one tepal or one petal and one sepal and so on. It may or may not be possible to divide the flower into symmetrical halves by the same number of longitudinal planes passing through the axis: Oleander is an example of a flower without such mirror planes. Actinomorphic flowers are also called radially symmetrical or regular flowers. Other examples of actinomorphic flowers are the lily (''Lilium'', Liliaceae) and the buttercup (''Ranunculus'', Ranunculaceae). Zygomorphic Zygomorp ...
