Senecio Ficoides
''Curio ficoides'', syn. ''Senecio ficoides'', also known as skyscraper Senecio and Mount Everest Senecio, is a species of succulent plant, in the genus ''Curio'' (Asteraceae), indigenous to South Africa. Description A succulent, spreading shrub, it reaches over 1 meter in height. The brittle, succulent branches lose their leaves lower down. The leaves are blue-green to blue grey, pruinose, succulent, erect, tapering and flattened laterally, with translucent lines down both sides. The flower capitula have no ray florets, and appear on a terminal, branching inflorescence. Relatives This is a polyploid species (2n=100).

Carolus Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his Nobility#Ennoblement, ennoblement in 1761 as Carl von Linné#Blunt, 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 (biology), 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 ...

Pseudanthium
A pseudanthium (Greek for "false flower"; ) is an inflorescence that resembles a flower. The word is sometimes used for other structures that are neither a true flower nor a true inflorescence. Examples of pseudanthia include flower heads, composite flowers, or capitula, which are special types of inflorescences in which anything from a small cluster to hundreds or sometimes thousands of flowers are grouped together to form a single flower-like structure. Pseudanthia take various forms. The real flowers (the florets) are generally small and often greatly reduced, but the pseudanthium itself can sometimes be quite large (as in the heads of some varieties of sunflower). Pseudanthia are characteristic of the daisy and sunflower family (Asteraceae), whose flowers are differentiated into ray flowers and disk flowers, unique to this family. The disk flowers in the center of the pseudanthium are actinomorphic and the corolla is fused into a tube. Flowers on the periphery are zygomorp ...

Curio Talinoides
''Curio talinoides'', syn. ''Senecio mandraliscae'', also known as blue straws, blue chalksticks, dassieharpuis, or narrow-leaf chalk sticks, is a succulent plant of the family Asteraceae that is native to South Africa. The origin of this plant is dubious and it may be a hybrid. Description The bluest of the curio plants, it is about 50 to 70 cm tall with 4.5-9.5 cm long leaves that are thickly and alternately arranged, jammed on the stems, and are set about 0.3-0.5 cm aside. The leaves are linear, rising, sickle shaped and would be narrow at both ends. Unlike the similar looking Curio repens, its leaves are much narrower and elongated. Curio repens is also easily distinguished by its shorter, often boat-shaped leaves. It is also easily confused with '' Curio ficoides'', which has a similar growth habit. However, the leaves of ''C. talinoides'' are rounded-cylindrical in cross section. In contrast, the leaves of ''C. ficoides'' are usually somewhat knife-like, fl ...

Curio Radicans
''Curio radicans'', syn. ''Senecio radicans'', is a succulent houseplant that is native to South Africa. A member of the family Asteraceae, the asters, this species is closely related to the common string of pearls and ''Curio hallianus''. It has multiple tendrils of glossy, banana-shaped foliage. It is commonly known as string of bananas or fishhook senecio. Like most members of the ''Curio'' genus, ''C. radicans'' is relatively hardy and easy to grow, making it a great starting point for novice gardeners and those seeking entry to the succulent or container gardening hobbies.Mace. "Cactus and Succulents: A Care Manual", Mace, Tony and Suzanne, 2001, Laurel Glen Publishing An interesting addition to any home or garden, ''C. radicans'' is especially good for pots, hanging baskets, succulent gardens, and other areas in need of textural interest.Baldwin.

Curio Repens
''Curio repens'', syn. ''Senecio serpens'', is a species of the genus ''Curio'' in the Asteraceae family. A succulent endemic to the Western Cape province of South Africa, it is typically found growing from crevices in rocky sandstone slopes. Commonly named blue chalksticks, it is used as an ornamental plant. Description It is a semi-trailing, low-growing dwarf shrub that forms a dense mat that reaches only about 20 cm in height and features silvery-blueish, finger-like fleshy leaves. It produces small and round, pompom-like flowers that may superficially resemble a virus. The flowers appear as off-white from distance, but would have yellow and pink tinges on the stamen up-close. Flowering season is usually between spring and autumn. It was first formally described as ''Cacalia repens'' by Carl Linnaeus in 1767. It should be distinguished from ''Curio talinoides'' by its shorter, broader and often boat-shaped leaves. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk is al ...

Pruinose
Pruinescence , or pruinosity, is a "frosted" or dusty-looking coating on top of a surface. It may also be called a pruina (plural: ''pruinae''), from the Latin word for hoarfrost. The adjectival form is pruinose . Entomology In insects, a "bloom" caused by wax particles on top of an insect's cuticle covers up the underlying coloration, giving a dusty or frosted appearance. The pruinescence is commonly white to pale blue in color but can be gray, pink, purple, or red; these colors may be produced by Tyndall scattering of light. When pale in color, pruinescence often strongly reflects ultraviolet. Pruinescence is found in many species of Odonata, particularly damselflies of the families Lestidae and Coenagrionidae, where it occurs on the wings and body. Among true dragonflies it is most common on male Libellulidae (skimmers). In the common whitetail and blue dasher dragonflies (''Plathemis lydia'' and ''Pachydiplax longipennis''), males display the pruinescence on the back of th ...

Glaucous
''Glaucous'' (, ) is used to describe the pale grey or bluish-green appearance of the surfaces of some plants, as well as in the names of birds, such as the glaucous gull (''Larus hyperboreus''), glaucous-winged gull (''Larus glaucescens''), glaucous macaw (''Anodorhynchus glaucus''), and glaucous tanager (''Thraupis glaucocolpa''). The term ''glaucous'' is also used botanically as an adjective to mean "covered with a greyish, bluish, or whitish waxy coating or bloom that is easily rubbed off" (e.g. glaucous leaves). The first recorded use of ''glaucous'' as a color name in English was in the year 1671. Examples The epicuticular wax coating on mature plum fruit gives them a glaucous appearance. Another familiar example is found in the common grape genus (''Vitis vinifera''). Some cacti have a glaucous coating on their stem(s). Glaucous coatings are hydrophobic so as to prevent wetting by rain. Their waxy character serves to hinder climbing of leaves, stem or fruit by insec ...

Senecio Ficoides Pm
''Senecio'' is a genus of flowering plants in the daisy family (Asteraceae) that includes ragworts and groundsels. Variously circumscribed taxonomically, the genus ''Senecio'' is one of the largest genera of flowering plants. Description Morphology The flower heads are normally rayed with the heads borne in branched clusters, and usually completely yellow, but green, purple, white and blue flowers are known as well. In its current circumscription, the genus contains species that are annual or perennial herbs, shrubs, small trees, aquatics or climbers. The only species which are trees are the species formerly belonging to '' Robinsonia'' occurring on the Juan Fernández Islands. Chemistry Pyrrolizidine alkaloids are found in all ''Senecio'' species. These alkaloids serve as a natural biocides to deter or even kill animals that would eat them. Livestock generally do not find them palatable. ''Senecio'' species are used as food plants by the larvae of some Lepidoptera species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
