Mimetes
''Mimetes'', the pagoda, is a genus of evergreen shrubs or small trees high, with thirteen species assigned to the family Proteaceae. This genus, as with other proteas, is popular with nectarivorous birds such as the Cape sugarbird and several sunbird species. All species of ''Mimetes'' are endemic to the Cape Floristic Region of South Africa. Description The thirteen species currently assigned to the genus ''Mimetes'' are evergreen, low shrubs to small trees of high. Its leaves lack stipules, are set alternately along the branches, without a leaf stalk, at an upward angle or more or less overlapping, long inverted egg-shaped, oval or long diamond-shaped, long and wide, with an entire margin, thickened at the tip and often with mostly three teeth clustered close together. After the flower heads in the axils of the leaves have been shed, the dormant growing tip is activated and produces the next inflorescence. It has twelve homologous sets of chromosomes (2n=24).

Mimetes Cucullatus
''Mimetes cucullatus'' is an evergreen shrub with several, mostly not branching, upright stems of 1–2 m (3–7 ft) high, that has been assigned to the family Proteaceae. It is the most widespread and most common pagoda species that can cope with a relatively large range of environmental circumstances. It is known under several names including common pagoda in English and rooistompie in Afrikaans. Description ''Mimetes cucullatus'' is an evergreen, upright shrub of 1–2 m (3–7 ft) high, that has a firm woody tuber in the ground, from which several stems rise. These stems are upright, 3–8 mm (0.12–0.32 in) thick, mostly not branching but occasionally forking, initially covered in grey felty hair, but this tends to wear off with age. The leaves are alternately set along the stems, very narrow to broad elliptic or inverted egg-shaped, 2½–5½ cm (1–2¼ in) long and ½–2 cm (0.2–0.8 in) wide. Young growth is scarlet c ...

Proteaceae
The Proteaceae form a family (biology), family of flowering plants predominantly distributed in the Southern Hemisphere. The family comprises 83 genus, genera with about 1,660 known species. Australia and South Africa have the greatest concentrations of diversity. Together with the Platanaceae (plane trees), Nelumbonaceae (the sacred lotus) and in the recent APG IV system the Sabiaceae, they make up the order Proteales. Well-known Proteaceae genera include ''Protea'', ''Banksia'', ''Embothrium'', ''Grevillea'', ''Hakea'', and ''Macadamia''. Species such as the New South Wales waratah (''Telopea speciosissima''), king protea (''Protea cynaroides''), and various species of ''Banksia'', ''Grevillea'', and ''Leucadendron'' are popular cut flowers. The nuts of ''Macadamia integrifolia'' are widely grown commercially and consumed, as are those of ''Gevuina avellana'' on a smaller scale. Etymology The name Proteaceae was adapted by Robert Brown (botanist, born 1773), Robert Brown from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acanthus (plant)
''Acanthus'' is a genus of about 30 species of flowering plants in the family Acanthaceae, native to tropical and warm temperate regions, with the highest species diversity in the Mediterranean Basin and Asia. This flowering plant is nectar-producing and depends on butterflies, such as '' Anartia fatima'', and other nectar-feeding organisms to distribute its pollen. Common names include Acanthus and bear's breeches. The generic name derives from the Greek term (''akanthos'') for '' Acanthus mollis'', a plant that was commonly imitated in Corinthian capitals. The genus comprises herbaceous perennial plants, rarely subshrubs, with spiny leaves and flower spikes bearing white or purplish flowers. Size varies from in height. Species 29 species are accepted: #'' Acanthus albus'' #'' Acanthus arboreus'' Forssk. (1775) #'' Acanthus austromontanus'' Vollesen — This species is native to southwestern Tanzania #'' Acanthus carduaceus'' #'' Acanthus caroli-alexandri'' (Syn. ' ...

Carl Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist 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 the son of a curate and was born in Råshult, in the countryside of Småland, 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 co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Paradisus Londinensis
''The Paradisus Londonensis'' (full title ''The Paradisus Londonensis : or Coloured Figures of Plants Cultivated in the Vicinity of the Metropolis'') is a book dated 1805–1808, printed by D.N. Shury, and published by William Hooker.. It consists of coloured illustrations of 117 plants drawn by William Hooker, with explanatory text by Richard Anthony Salisbury. Publication ''The Paradisus Londinensis'' was constructed as two volumes, each of two parts. The plates were in one part, the text in the other. The title page of the first volume and part bears the date 1805 and identifies the illustrator and publisher as Hooker. The title page of the second part identifies the author of the text as Salisbury. It has often been catalogued as 1805–1807, although some later plates are dated 1808.

William Hooker (botanical Illustrator)
William Hooker (1779–1832) was a Great Britain, British illustrator of natural history. He studied under Franz Bauer (1758–1840), becoming the official artist of the Royal Horticultural Society from 1812 until retirement in 1820, whose publications he illustrated. His paintings of fruit were particularly appreciated. Hooker also worked on the ''Oriental Memoirs'' of James Forbes (botanist), James Forbes and ''The Paradisus Londinensis'', with descriptions by Richard Anthony Salisbury (1761–1829). He contributed illustrations for ''Hooker's Finest Fruits'' until his death in 1832. See also * Hooker's green, a green pigment, useful for representing leaves.

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 sporangium, 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 Flowering plant, angiosperms. The megagametophyte produces an ovum, 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. On the basis of the relative position of micropyle, body of the ovule, chalaza and funicle, there are six types of ovules. Location within the plant In flowering plants, the ovule is located inside the portion of the flower called the gynoecium. The Ovary (plants), ovary of the gynoecium p ...

Ovary (botany)
In the flowering plants, an ovary is a part of the female reproductive organ of the flower or gynoecium. Specifically, it is the part of the pistil which holds the ovule(s) and is located above or below or at the point of connection with the base of the petals and sepals. The pistil may be made up of one carpel or of several fused carpels (e.g. dicarpel or tricarpel), and therefore the ovary can contain part of one carpel or parts of several fused carpels. Above the ovary is the Style (botany), style and the stigma, which is where the pollen lands and germinates to grow down through the style to the ovary, and, for each individual pollen grain, to fertilize one individual ovule. Some wind pollinated flowers have much reduced and modified ovaries. Fruits A fruit is the mature, ripened ovary of a flower following double fertilization in an angiosperm. Because gymnosperms do not have an ovary but reproduce through fertilization of unprotected ovules, they produce naked seeds th ...

Pollen Presenter
A pollen-presenter is an area on the tip of the Stigma_(botany)#Style, style in flowers of plants of the family Proteaceae on which the Stamen#Morphology_and_terminology, anthers release their pollen prior to anthesis. To ensure pollination, the style grows during anthesis, sticking out the pollen-presenter prominently, and so ensuring that the pollen easily contacts the bodies of potential pollination vectors such as bees, birds and Nectarivore, nectarivorous mammals. The systematic depositing of pollen on the tip of the style implies the plants have some strategy to avoid excessive self-pollination.

Stigma (botany)
The stigma (: stigmas or stigmata) is the receptive tip of a Gynoecium#Carpels, carpel, or of several fused carpels, in the gynoecium of a flower. Description The stigma, together with the Style (botany), style and ovary (botany), 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 germination, 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 (Pollination syndrome#Biotic, ...

Stamen
The stamen (: stamina or stamens) is a part consisting of the male reproductive organs 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 (each lobe is termed a locule) and are attached to the filament either at the base or in the middle area of the anther. The sterile (i.e. nonreproductive) tissue between the lobes is called the Connective (botany), 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 size of anthers differs greatly, from a tiny fraction of a millimeter in ''Wolfia'' spp up to five inches (13 centimeters) in ''Canna iridiflora'' and ''Strelitzia nicolai''.

Perianth
The perianth (perigonium, perigon or perigone in monocots) is the non-reproductive part of the flower. It is a structure that forms an envelope surrounding the sexual organs, consisting of the calyx (sepals) and the corolla (petals) or tepals when called a perigone. The term ''perianth'' is derived from Greek περί (, "around") and άνθος (, "flower"), while ''perigonium'' is derived from περί () and γόνος (, "seed, sex organs"). In the mosses and liverworts (Marchantiophyta), the perianth is the sterile (neither male nor female) tubelike tissue that surrounds the female reproductive structure or developing sporophyte. Flowering plants In flowering plants, the perianth may be described as being either dichlamydeous/heterochlamydeous in which the calyx and corolla are clearly separate, or homochlamydeous, in which they are indistinguishable (and the sepals and petals are collectively referred to as tepals). When the perianth is in two whorls, it is desc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
