Pelargonium Cucullatum
''Pelargonium cucullatum'' is a hairy, upright, branching, perennial shrub, of high, that has been assigned to the cranesbill family. It sprouts new stems from the underground rootstock and becomes woody at its base. It has alternately set, sometimes slightly succulent leaves crowded near the top of the branches, with leaf stalks and flat to hood-shaped leaf blades, with a rounded broad triangular to kidney-shaped outline of about long and wide, often somewhat incised, the margin with irregular teeth. The white to purplish red, 5-merous, somewhat mirror symmetrical flowers grow in umbel-like clusters, and each contain mostly 7 fertile stamens and 3 infertile staminodes (best checked in the bud) of different length. ''P. cucullatum'' has been cultivated as a garden ornamental and house plant since the 17th century. It has been used to breed many modern pelargonium hybrids, notably the Regal pelargoniums. It is called hooded-leaf pelargonium or herba althaea in English and wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape Peninsula
The Cape Peninsula () of South Africa is a generally mountainous peninsula that juts out into the Atlantic Ocean at the south-western extremity of the African continent. At the southern end of the peninsula are Cape Point and the Cape of Good Hope. On the northern end is Table Mountain, overlooking Table Bay and the City Bowl of Cape Town, South Africa. The peninsula is 52 km long from Mouille point in the north to Cape Point in the south. The Peninsula has been an island on and off for the past 5 million years, as sea levels fell and rose with the Glacial period, ice age and interglacial global warming cycles of, particularly, the Pleistocene. The last time that the Peninsula was an island was about 1.5 million years ago. Soon afterwards it was joined to the mainland by the Geology of Cape Town#Tertiary to Recent events, emergence from the sea of the sandy area now known as the Cape Flats. The towns and villages of the Cape Peninsula and Cape Flats, and the undev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Umbel
UMBEL (Upper Mapping and Binding Exchange Layer) is a logically organized knowledge graph of 34,000 concepts and entity types that can be used in information science for relating information from disparate sources to one another. It was retired at the end of 2019. UMBEL was first released in July 2008. Version 1.00 was released in February 2011. Its current release is version 1.50. The grounding of this information occurs by common reference to the permanent URIs for the UMBEL concepts; the connections within the UMBEL upper ontology enable concepts from sources at different levels of abstraction or specificity to be logically related. Since UMBEL is an open-source extract of the OpenCyc knowledge base, it can also take advantage of the reasoning capabilities within Cyc. UMBEL has two means to promote the semantic interoperability of information:. It is: * An ontology of about 35,000 reference concepts, designed to provide common mapping points for relating different on ...

Hortus Kewensis
(Latin for 'Kew Garden'; abbr. ) is a series of works cataloguing the plant species in cultivation at the Royal Botanic Gardens at Kew in the late 18th and early 19th centuries. Background Kew became a favored location for English courtiers after the establishment of Richmond Palace nearby under the Tudors. The Royal Botanic Gardens at Kew began as the private garden of Henry Capell of Tewkesbury and then Samuel Molyneux, who served as secretary to Frederick, Prince of Wales, son of George II and father of George III of England. Frederick then leased Kew House, began planning an enormous greenhouse, and had his close friend John Stuart, earl of Bute, begin requesting plant specimens from British agents around the world. After his death, Frederick's widow Augusta expanded its gardens still further in cooperation with Bute and William Aiton. John Hill's edition The first edition of was published in Latin in 1768. It was compiled by John Hill at Augusta's request and lis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Bentinck, 1st Earl Of Portland
William Bentinck, 1st Earl of Portland ( Dutch: ''Hans Willem Bentinck''; 20 July 164923 November 1709) was a Dutch-born English nobleman who became in an early stage the favourite of William, Prince of Orange, Stadtholder in the Netherlands, and future King of England. He was reportedly steady, sensible, modest and usually moderate. The friendship and cooperation stopped in 1699. Biography Early life and nurse to Prince William Hans Willem was born in Diepenheim, Overijssel, the son of Bernard, Baron Bentinck, and was descended from an ancient and noble family of Guelders and Overijssel. He was appointed first page of honour and chamberlain. When, in 1675, Prince William was attacked by smallpox, his physicians suggested he sleep with one of his pages to absorb "animal spirits" from a young, healthy body. Bentinck was the page and he nursed the prince assiduously back to health. This devotion secured for him the special and enduring friendship of William. From that poi ...

Paul Hermann (botanist)
Paul Hermann (30 June 1646, Halle – 29 January 1695, Leiden) was a German-born physician and botanist who for 15 years was director of the Hortus Botanicus Leiden. Born in Halle, Saxony-Anhalt, Germany, Paul Hermann was the son of Johann Hermann, a well-known organist, and Maria Magdalena Röber, a clergyman's daughter. Hermann studied theology and medicine in Wittenberg and botany in Leipzig. After graduating from Europe's finest medical school, Padua in 1670, he was then engaged by the Dutch East India Company and went to Ceylon (now Sri Lanka) as a Ship's Medical Officer. He was in their employ from 1672 to 1677. During his stay there, he made a scientific collection of this island's plants and other organisms. He was then offered the job at Leiden and took up the Chair of Botany at the University of Leiden in 1679 and took up his residence in 1680 at Leiden where he spent the rest of his professional life. He immediately set to making it the finest botanical garden in Eu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mericarp
A schizocarp is a dry fruit that, when mature, splits up into mericarps. There are different definitions: * Any dry fruit composed of multiple carpels that separate. : Under this definition the mericarps can contain one or more seeds (the mericarps of ''Abutilon'' have two or more seeds) and each mericarp can be either: :* Indehiscent (remaining closed), such as in the carrot and other Umbelliferae or in members of the genus '' Malva'', or :* Dehiscent (splitting open to release the seed), for example members of the genus ''Geranium''. This is similar to what happens with a capsule, but with an extra stage. (In ''Abutilon'', the mericarp is sometimes only partially dehiscent and does not release the seed.) * Any fruit that separates into indehiscent one-seeded segments, such as a loment A loment (or lomentum) is a part of certain legume plants. It is a type of dehiscent fruit that breaks apart at the constrictions occurring between segments, so that each segment contain ...

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, ...

Pollen
Pollen is a powdery substance produced by most types of flowers of seed plants for the purpose of sexual reproduction. It consists of pollen grains (highly reduced Gametophyte#Heterospory, microgametophytes), which produce male gametes (sperm cells). Pollen grains have a hard coat made of sporopollenin that protects the gametophytes during the process of their movement from the stamens to the pistil of flowering plants, or from the male Conifer cone, cone to the female cone of gymnosperms. If pollen lands on a compatible pistil or female cone, it Germination, germinates, producing a pollen tube that transfers the sperm to the ovule containing the female gametophyte. Individual pollen grains are small enough to require magnification to see detail. The study of pollen is called palynology and is highly useful in paleoecology, paleontology, archaeology, and Forensic science, forensics. Pollen in plants is used for transferring Ploidy#Haploid and monoploid, haploid male genetic ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anther
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''. The stamens in a flower ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glossary Of Leaf Morphology
The following terms are used to describe leaf plant morphology, morphology in the description and taxonomy (biology), taxonomy of plants. Leaves may be simple (that is, the leaf blade or 'lamina' is undivided) or compound (that is, the leaf blade is divided into two or more leaflet (botany), leaflets). The edge of the leaf may be regular or irregular, and may be smooth or have hair, bristles, or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf#Terminology, leaf article. The terms listed here all are supported by technical and professional usage, but they cannot be represented as mandatory or undebatable; readers must use their judgement. Authors often use terms arbitrarily, or coin them to taste, possibly in ignorance of established terms, and it is not always clear whether because of ignorance, or personal preference, or because usages change with time or context, or because of variation between specimens, even specimens from ...

Petal
Petals are modified leaves that form an inner whorl surrounding the reproductive parts of flowers. They are often brightly coloured or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually surrounded by an outer whorl of modified leaves called sepals, that collectively form the ''calyx'' and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term ''tepal'' is appropriate include genera such as '' Aloe'' and '' Tulipa''. Conversely, genera such as '' Rosa'' and '' Phaseolus'' have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly coloured tepals. Since they ...
