Anemone Thomsonii
''Anemone thomsonii'' is a species of flowering plant in the buttercup family Ranunculaceae. It is a low to high (7–70 cm) geophyte A storage organ is a part of a plant specifically modified for storage of energy (generally in the form of carbohydrates) or water. Storage organs often grow underground, where they are better protected from attack by herbivores. Plants that have ... with finely divided leaves from the ground, and a stem that carries one flower, which has about twenty sepals, that are white or light pink inside and mostly have a very wide purple stripe at the outside. The species is limited to the highlands of East Africa. Description ''Anemone thomsonii'' is a geophyte with a short and stout rhizome. The leaves at the base are 3–40 cm, usually totally split into three, each of which is again split into three, and this is repeated a third time so that one leaf is composited of about twenty seven lobes, each of which itself is more or less deeply inc ...

Daniel Oliver (botanist)
Daniel Oliver, FRS (6 February 1830, Newcastle upon Tyne – 21 December 1916) was an English botanist. He was Librarian of the Herbarium, Royal Botanic Gardens, Kew from 1860–1890 and Keeper there from 1864–1890, and Professor of Botany at University College, London from 1861–1888. In 1864, while at UCL, he published ''Lessons in Elementary Biology'', based upon material left in manuscript by John Stevens Henslow, and illustrated by Henslow's daughter, Anne Henslow Barnard of Cheltenham. With a second edition in 1869 and a third in 1878 this book was reprinted until at least 1891. Oliver regarded this book as suitable for use in schools and for young people remote from the classroom and laboratory. He was elected a member of the Linnean Society, awarded their Gold Medal in 1893, and awarded a Royal Medal by the Royal Society in 1884. He married in 1861 and was the father of two daughters and a son, Francis Wall Oliver. In 1895, botanist Tiegh published ''Oliverella'', ...

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] |
Plants Described In 1885
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the abili ...

Anemone
''Anemone'' () is a genus of flowering plants in the buttercup family Ranunculaceae. Plants of the genus are commonly called windflowers. They are native to the temperate and subtropical regions of all continents except Australia, New Zealand and Antarctica. The genus is closely related to several other genera including '' Anemonoides'', '' Anemonastrum'', ''Hepatica'', and '' Pulsatilla''. Some botanists include these genera within ''Anemone''. Description ''Anemone'' are perennials that have basal leaves with long leaf-stems that can be upright or prostrate. Leaves are simple or compound with lobed, parted, or undivided leaf blades. The leaf margins are toothed or entire. Flowers with 4–27 sepals are produced singly, in cymes of 2–9 flowers, or in umbels, above a cluster of leaf- or sepal-like bracts. Sepals may be any color. The pistils have one ovule. The flowers have nectaries, but petals are missing in the majority of species. The fruits are ovoid to obovo ...

Mount Kenya
Mount Kenya ( Kikuyu: ''Kĩrĩnyaga'', Kamba, ''Ki Nyaa'') is the highest mountain in Kenya and the second-highest in Africa, after Kilimanjaro. The highest peaks of the mountain are Batian (), Nelion () and Point Lenana (). Mount Kenya is located in the former Eastern and Central provinces of Kenya; its peak is now the intersection of Meru, Embu, Laikipia, Kirinyaga, Nyeri and Tharaka Nithi counties, about south of the equator, around north-northeast of the capital Nairobi. Mount Kenya is the source of the name of the Republic of Kenya. Mount Kenya is a volcano created approximately 3 million years after the opening of the East African Rift. Before glaciation, it was high. It was covered by an ice cap for thousands of years. This has resulted in very eroded slopes and numerous valleys radiating from the peak. There are currently 11 small glaciers, which are shrinking rapidly, and may disappear by 2050. The forested slopes are an important source of water for much of ...

Aberdare Range
The Aberdare Range (formerly the Sattima Range, Kikuyu: ''Nyandarua'') is a 160 km (100 mile) long mountain range of upland, north of Kenya's capital Nairobi with an average elevation of . It straddles across the counties of Nyandarua, Nyeri, Muranga, Kiambu and Laikipia. The mountain range is located in west central Kenya, northeast of Naivasha and Gilgil and lies just south of the Equator. The mountain range is called Nyandarua among the Agikuyu people in whose territory this forest and mountain range is located. The name Nyandarua comes from the Kikuyu word rwandarua meaning a drying hide, due to the distinctive fold of its silhouette. Topology The Aberdare Range forms a section of the eastern rim of the Great Rift Valley running roughly north to south. On the west, the range falls off steeply into the Kinangop Plateau and then into the Great Rift Valley. On the east, the range slopes more gently. Lake Naivasha and the distant Mau Escarpment can be seen from peaks in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Kilimanjaro
Mount Kilimanjaro () is a dormant volcano in Tanzania. It has three volcanic cones: Kibo, Mawenzi, and Shira. It is the highest mountain in Africa and the highest free-standing mountain above sea level in the world: above sea level and about above its plateau base. It is the highest volcano in Africa and the Eastern Hemisphere. Kilimanjaro is the fourth most topographically prominent peak on Earth. It is part of Kilimanjaro National Park and is a major hiking and climbing destination. Because of its shrinking glaciers and ice fields, which are projected to disappear between 2025 and 2035, it has been the subject of many scientific studies. Toponymy The origin of the name Kilimanjaro is not known, but a number of theories exist. European explorers had adopted the name by 1860 and reported that Kilimanjaro was the mountain's Kiswahili name. The 1907 edition of ''The Nuttall Encyclopædia'' also records the name of the mountain as Kilima-Njaro. Johann Ludwig Kr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Hanang
Mount Hanang is a mountain in northern Tanzania. The peak has an elevation of 3,420 m above sea level. Hanang is located in Manyara Region's Hanang District. It is (after Mount Kilimanjaro, Mount Meru and Mount Loolmalasin) the fourth-highest mountain in Tanzania, if you count the three peaks of Kilimanjaro as one mountain. The principal path to the summit starts in the town of Katesh. The climb can be done in one day (10 hours), but it is also common for climbers to spend one night in a tented camp on the mountain and reach the summit on the second day. Hanang Forest Reserve Mount Hanang Nature Forest Reserve has an area of 58.66 km², protecting an enclave of evergreen montane forest on the mountain's higher slopes. Between 2000 and 2700 meters elevation, evergreen montane forest covers the mountain's wetter eastern and southern slopes, while the drier western and northern slopes are home to dry montane evergreen forest with bushland and grassland on the ridges. Above 2700 m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, '' Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia l ...

Joseph Thomson (explorer)
Joseph Thomson (14 February 1858 – 2 August 1895) was a British geologist and explorer who played an important part in the Scramble for Africa. Thomson's gazelle and Thomson's Falls, Nyahururu are named after him. Excelling as an explorer rather than an exact scientist, he avoided confrontations among his porters or with indigenous peoples, neither killing any native nor losing any of his men to violence. His motto is often quoted to be ''"He who goes gently, goes safely; he who goes safely, goes far."'' Early life Born in Penpont, Dumfriesshire, he was apprenticed into his father's stone-masonry and quarrying business. He developed a keen amateur interest in geology and botany, which eventually led to his formal education at the University of Edinburgh, studying under Archibald Geikie and Thomas Henry Huxley. Royal Geographical Society On graduating in 1878, he was appointed geologist and naturalist to Alexander Keith Johnston's Royal Geographical Society expedition to ...

Achene
An achene (; ), also sometimes called akene and occasionally achenium or achenocarp, is a type of simple dry fruit produced by many species of flowering plants. Achenes are monocarpellate (formed from one carpel) and indehiscent (they do not open at maturity). Achenes contain a single seed that nearly fills the pericarp, but does not adhere to it. In many species, what is called the "seed" is an achene, a fruit containing the seed. The seed-like appearance is owed to the hardening of the fruit wall (pericarp), which encloses the solitary seed so closely as to seem like a seed coat. Examples The fruits of buttercup, buckwheat, caraway, quinoa, amaranth, and cannabis are typical achenes. The achenes of the strawberry are sometimes mistaken for seeds. The strawberry is an accessory fruit with an aggregate of achenes on its outer surface, and what is eaten is accessory tissue. A rose produces an aggregate of achene fruits that are encompassed within an expanded hypanthium ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
