Acanthocereus Tetragonus
''Acanthocereus tetragonus'', is a species of cactus that is native to Florida and the Lower Rio Grande Valley of Texas in the United States, Mexico, Central America, the Caribbean, and northern South America. The species is invasive in New Caledonia. Common names include night-blooming cereus, barbed-wire cactus, sword-pear, dildo cactus, triangle cactus, and Órgano-alado de pitaya (Spanish). The miniature cultivar is known as fairy castle cactus. It was originally described by Carl Linnaeus in 1753 as ''Cactus tetragonus'' but was moved to the genus ''Acanthocereus'' in 1938 by Pieter Wagenaar Hummelinck. Description ''Acanthocereus tetragonus'' is a tall, columnar cactus that reaches a height of . Stems are dark green, have three to five angles, and are in diameter. Areoles are grey and separated by . Central areoles have one to two spines up to long, while radial areoles have six to eight spines up to in length. The flowers are in diameter with a tube in length. Outer ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ...

Acanthocereus
''Acanthocereus'' is a genus of cactus, cacti. Its species take the form of shrubs with arching or climbing stems up to several meters in height. The generic name is derived from the Greek language, Greek word ''άκανθα'' (''acantha''), meaning spine, and the Latin word ''cereus'', meaning candle. The genus is native to the mostly Tropics, tropical Americas from Texas and the southern tip of Florida to the northern part of South America (Colombia and Venezuela), including islands of the Caribbean. Description The plants form bushes which later usually overhanging or spreading and are rarely tree-shaped. Stems have 3 to 5 ribs, typically thin, with stout spines. The large, white, funnel-shaped flowers are night-opening, long and in diameter and open at night. The little scaly pericarpel and the long, stiff, upright flower tube are covered with a few thorns that soon decay and little wool. The fruits are spherical to ovoid or pear-shaped red or green, bare or thorny, tear ...

Vegetable
Vegetables are parts of plants that are consumed by humans or other animals as food. The original meaning is still commonly used and is applied to plants collectively to refer to all edible plant matter, including the flowers, fruits, stems, leaves, roots, and seeds. An alternative definition of the term is applied somewhat arbitrarily, often by culinary and cultural tradition. It may exclude foods derived from some plants that are fruits, flowers, nuts, and cereal grains, but include savoury fruits such as tomatoes and courgettes, flowers such as broccoli, and seeds such as pulses. Originally, vegetables were collected from the wild by hunter-gatherers and entered cultivation in several parts of the world, probably during the period 10,000 BC to 7,000 BC, when a new agricultural way of life developed. At first, plants which grew locally would have been cultivated, but as time went on, trade brought exotic crops from elsewhere to add to domestic types. Nowadays, ...

Castle
A castle is a type of fortified structure built during the Middle Ages predominantly by the nobility or royalty and by military orders. Scholars debate the scope of the word ''castle'', but usually consider it to be the private fortified residence of a lord or noble. This is distinct from a palace, which is not fortified; from a fortress, which was not always a residence for royalty or nobility; from a ''pleasance'' which was a walled-in residence for nobility, but not adequately fortified; and from a fortified settlement, which was a public defence – though there are many similarities among these types of construction. Use of the term has varied over time and has also been applied to structures such as hill forts and 19th-20th century homes built to resemble castles. Over the approximately 900 years when genuine castles were built, they took on a great many forms with many different features, although some, such as curtain walls, arrowslits, and portcullises, were ...

Turret (architecture)
In architecture, a turret is a small tower that projects vertically from the wall of a building such as a medieval castle. Turrets were used to provide a projecting defensive position allowing covering fire to the adjacent wall in the days of military fortification. As their military use faded, turrets were used for decorative purposes, as in the Scottish baronial style. A turret can have a circular top with crenellations as seen in the picture at right, a pointed roof, or other kind of apex. It might contain a staircase if it projects higher than the building; however, a turret is not necessarily higher than the rest of the building; in this case, it is typically part of a room, that can be simply walked into – see the turret of Chateau de Chaumont on the collection of turrets, which also illustrates a turret on a modern skyscraper. A building may have both towers and turrets; towers might be smaller or higher, but turrets instead project from the edge of a building ra ...

Branch
A branch, sometimes called a ramus in botany, is a woody structural member connected to the central trunk (botany), trunk of a tree (or sometimes a shrub). Large branches are known as boughs and small branches are known as twigs. The term ''twig'' usually refers to a wikt:terminus, terminus, while ''bough'' refers only to branches coming directly from the trunk. Due to a broad range of species of trees, branches and twigs can be found in many different shapes and sizes. While branches can be nearly vertical and horizontal, horizontal, vertical, or diagonal, the majority of trees have upwardly diagonal branches. A number of mathematical properties are associated with tree branchings; they are natural examples of fractal patterns in nature, and, as observed by Leonardo da Vinci, their cross section (geometry), cross-sectional areas closely follow the da Vinci branching rule. Terminology Because of the enormous quantity of branches in the world, there are numerous names in Engl ...

Cultivar
A cultivar is a type of cultivated plant that people have selected for desired traits and when propagated retain those traits. Methods used to propagate cultivars include: division, root and stem cuttings, offsets, grafting, tissue culture, or carefully controlled seed production. Most cultivars arise from purposeful human manipulation, but some originate from wild plants that have distinctive characteristics. Cultivar names are chosen according to rules of the International Code of Nomenclature for Cultivated Plants (ICNCP), and not all cultivated plants qualify as cultivars. Horticulturists generally believe the word ''cultivar''''Cultivar'' () has two meanings, as explained in ''Formal definition'': it is a classification category and a taxonomic unit within the category. When referring to a taxon, the word does not apply to an individual plant but to all plants that share the unique characteristics that define the cultivar. was coined as a term meaning "cultivated variety ...

Fairy Castles Buds
A fairy (also fay, fae, fey, fair folk, or faerie) is a type of mythical being or legendary creature found in the folklore of multiple European cultures (including Celtic, Slavic, Germanic, English, and French folklore), a form of spirit, often described as metaphysical, supernatural, or preternatural. Myths and stories about fairies do not have a single origin, but are rather a collection of folk beliefs from disparate sources. Various folk theories about the origins of fairies include casting them as either demoted angels or demons in a Christian tradition, as deities in Pagan belief systems, as spirits of the dead, as prehistoric precursors to humans, or as spirits of nature. The label of ''fairy'' has at times applied only to specific magical creatures with human appearance, magical powers, and a penchant for trickery. At other times it has been used to describe any magical creature, such as goblins and gnomes. ''Fairy'' has at times been used as an adjective, ...

Fruit
In botany, a fruit is the seed-bearing structure in flowering plants that is formed from the ovary after flowering. Fruits are the means by which flowering plants (also known as angiosperms) disseminate their seeds. Edible fruits in particular have long propagated using the movements of humans and animals in a symbiotic relationship that is the means for seed dispersal for the one group and nutrition for the other; in fact, humans and many animals have become dependent on fruits as a source of food. Consequently, fruits account for a substantial fraction of the world's agricultural output, and some (such as the apple and the pomegranate) have acquired extensive cultural and symbolic meanings. In common language usage, "fruit" normally means the seed-associated fleshy structures (or produce) of plants that typically are sweet or sour and edible in the raw state, such as apples, bananas, grapes, lemons, oranges, and strawberries. In botanical usage, the term "fruit" also i ...

Hemaris
''Hemaris'' is a genus of sphinx moths in the subfamily Macroglossinae, which is native to the Holarctic.Kitching, I. J. and J. Cadiou (2000). ''Hawkmoths of the World. An Annotated and Illustrated Revisionary Checklist (Lepidoptera: Sphingidae).'' Cornell University Press, New York. Their main host plants are herbs and shrubs of the teasel and honeysuckle families. Moths in genus ''Hemaris'' are known collectively as clearwing moths or hummingbird moths in the US and Canada and bee hawk-moths in Britain. The related Old World hummingbird hawk-moths, genus ''Macroglossum'', are similar in appearance and habits. Both genera have tails that are provided with an expansile truncated tuft of hairs, but only ''Hemaris'' has the disc of the wings transparent, as these scales are dropped soon after eclosion. Description The eggs are small, spherical, and pale glossy green in color. Host plants include shrub and vining honeysuckles and teasels. The larvae are small, cylindrical, and co ...

Pistil
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 calle ...
