Scadoxus Nutans
''Scadoxus nutans'' is a herbaceous plant endemic to southwest Ethiopia. Its red to pink flowers face downwards as the top of the flowering stem bends over, unlike any of the other species of ''Scadoxus''. It grows mainly as an epiphyte in tropical mountain forests, which are disappearing, making the species vulnerable to extinction. It is sometimes cultivated as an ornamental plant. Description ''Scadoxus nutans'' grows from a rhizome, with growth occurring mainly in spring and autumn. The whole plant is usually tall, occasionally as high as . The overlapping bases of the leaf stalks ( petioles) form a false stem or pseudostem, which emerges from the side of last year's pseudostem. The pseudostem is green, marked with brown spots, and is about long. The narrow leaf blades have wavy edges and spread out from the pseudostem, being up to long and wide. The flowers are borne on a leafless stalk ( scape), which is bent over during flowering so that the flowers face downwards. no ...

Herbaceous Plant
Herbaceous plants are vascular plants that have no persistent woody stems above ground. This broad category of plants includes many perennials, and nearly all annuals and biennials. Definitions of "herb" and "herbaceous" The fourth edition of the ''Shorter Oxford English Dictionary'' defines "herb" as: #"A plant whose stem does not become woody and persistent (as in a tree or shrub) but remains soft and succulent, and dies (completely or down to the root) after flowering"; #"A (freq. aromatic) plant used for flavouring or scent, in medicine, etc.". (See: Herb) The same dictionary defines "herbaceous" as: #"Of the nature of a herb; esp. not forming a woody stem but dying down to the root each year"; #"BOTANY Resembling a leaf in colour or texture. Opp. scarious". Botanical sources differ from each other on the definition of "herb". For instance, the Hunt Institute for Botanical Documentation includes the condition "when persisting over more than one growing season, the parts o ...

Fish Toxins
Fish toxins or fish stupefying plants have historically been used by many hunter gatherer cultures to stun fish, so they become easy to collect by hand. Some of these toxins paralyse fish, which can then be easily collected. The process of documenting many fish toxins and their use is ongoing, with interest in potential uses from medicine, agriculture, and industry. Theory Use of the herbal fish poisons has been documented in a number of sources involving catching fish from fresh and sea water. Tribal people historically used various plants for medicinal and food exploitation purposes. Use of fish poisons is a very old practice in the history of humankind. In 1212 AD, King Frederick II prohibited the use of certain plant piscicides, and by the 15th century, similar laws had been decreed in other European countries, as well. All over the globe, indigenous people use various fish poisons to kill fish, including America and among Tarahumara Indians. Herbal fish-stupefying agents ...

Arrow Poison
Arrow poisons are used to poison arrow heads or darts for the purposes of hunting and warfare. They have been used by indigenous peoples worldwide and are still in use in areas of South America, Africa and Asia. Notable examples are the poisons secreted from the skin of the poison dart frog, and curare (or 'ampi'), a general term for a range of plant-derived arrow poisons used by the indigenous peoples of South America. Poisoned arrows have featured in mythology, notably the Greek story of Heracles slaying the centaur Nessus using arrows poisoned with the blood of the Lernaean Hydra. The Greek hero Odysseus poisons his arrows with hellebore in Homer's ''Odyssey''. Poisoned arrows also figure in Homer's epic about the Trojan War, the ''Iliad'', in which both Achaeans and Trojans used toxic arrows and spears. Poisoned arrows are referred to in the Book of Job in the Bible, descriptive of the sufferings experienced by the just man, Job. The modern terms "toxic" and "toxin" derive f ...

Alkaloid
Alkaloids are a class of basic, naturally occurring organic compounds that contain at least one nitrogen atom. This group also includes some related compounds with neutral and even weakly acidic properties. Some synthetic compounds of similar structure may also be termed alkaloids. In addition to carbon, hydrogen and nitrogen, alkaloids may also contain oxygen, sulfur and, more rarely, other elements such as chlorine, bromine, and phosphorus.Chemical Encyclopedia: alkaloids xumuk.ru Alkaloids are produced by a large variety of organisms including , , Medicinal plant, plants, an ...

Scadoxus
''Scadoxus'' is a genus of African and Arabian plants in the Amaryllidaceae, Amaryllis family, subfamily Amaryllidoideae. The English names blood lily or blood flower are used for some of the species. The genus has close affinities with ''Haemanthus.'' Species of ''Scadoxus'' are grown as ornamental plants for their brilliantly coloured flowers, either in containers or in the ground in frost-free climates. Although some species have been used in traditional medicine, they contain poisonous alkaloids. Description Species of ''Scadoxus'' grow from bulbs or rhizomes. Bulbous species usually also have distinct rhizomes. Particularly in the non-bulbous species, the petiole (botany), petioles (leaf stalks) overlap to produce a false stem or pseudostem, which may be purple-spotted. The leaf blades are lanceolate to ovate with a thickened midrib. The leafless flowering stem (Scape (botany), scape) is also sometimes purple-spotted, and either appears from among the leaves or pushes thro ...

Tree Fern
The tree ferns are arborescent (tree-like) ferns that grow with a trunk elevating the fronds above ground level, making them trees. Many extant tree ferns are members of the order Cyatheales, to which belong the families Cyatheaceae (scaly tree ferns), Dicksoniaceae, Metaxyaceae, and Cibotiaceae. It is estimated that Cyatheales originated in the early Jurassic, and is the third group of ferns known to have given rise to tree-like forms. The others are the extinct '' Tempskya'' of uncertain position, and Osmundales where the extinct Guaireaceae and some members of Osmundaceae also grew into trees. In addition there were the Psaroniaceae and Tietea in the Marattiales, which is the sister group to most living ferns including Cyatheales. Other ferns which are also tree ferns, are ''Leptopteris'' and ''Todea'' in the family Osmundaceae, which can achieve short trunks under a metre tall. Fern species with short trunks in the genera ''Blechnum'', '' Cystodium'' and ''Sadleria'' from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NCCPG National Plant Collection
The National Plant Collection scheme is the main conservation vehicle whereby the Plant Heritage charity (formerly the National Council for the Conservation of Plants and Gardens) can accomplish its mission: to conserve, grow, propagate, document and make available the resource of garden plants that exists in the United Kingdom. With the National Plant Collections, individuals or organisations undertake to document, develop, and preserve a comprehensive collection of one group of plants in trust for the future. Most of the collections are composed of a related group, for example, a collection of oaks or daffodils. This allows the scheme to develop systematic coverage of cultivated plants in the United Kingdom. A few National Collections are of plants introduced by a prolific nursery or plant hunter; for example, the Sir Harold Hillier Gardens and Arboretum hold a collection of Hillier's introductions. Collection holders voluntarily subscribe to the scheme's ideals and strin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Illubabor Province
Illubabor (Amharic: ኢሉባቦር) was a province in the south-western part of Ethiopia, along the border with Sudan. The name Illubabor is said to come from two Oromo words, "Illu" and "Abba Bor(a)". "Illu" is a name of a clan, and "Abba Bor" was the horse name of Chali Shone, who founded the ruling family of the area when it was conquered by Shewa; hence IlluAbabor means the Illu belonging to Ababor(a). Originally, its capital city was Gore, then around 1978 the capital was moved to Metu. With the adoption of new constitution in 1995, the territory of Illubabor was divided between the Gambela, Oromia and the Southern Nations, Nationalities, and Peoples Regions of Ethiopia. History Illubabor was, by the late 19th century, an Oromo state facing the prospect of forcibly being absorbed into the Ethiopian Empire, whose reconsolidation of authority over long-abandoned peripheral territories had been intensifying since the ascension of Menelik II, who had begun his southern ...

Kaffa Province
Kaffa ( Amharic: ከፋ) was a province on the southwestern side of Ethiopia; its capital city was Bonga. It was named after the former Kingdom of Kaffa or "Kefa". Kaffa was bordered on the west by Sudan, on the northwest by Illubabor, on the north by Walega, on the northeast by Shewa, on the east by Sidamo, and on the southeast by Gamu-Gofa. Legendary accounts state that the etymology of Kaffa is from the Arabic ''qahwah'' meaning "a drink from berries". According to legend, ancestors of today's Kaffa people in southwest Ethiopia were the first to cultivate the coffee plant and recognise the energising effect of the coffee beverage. See also * Kingdom of Kaffa * History of Ethiopia Ethiopia is one of the oldest countries in Africa, the emergence of Ethiopian civilization dates back thousands of years. Due to migration and imperial expansion, it grew to include many other primarily Afro-Asiatic-speaking communities, includ ... References {{Coord, 7, N, 37, E, ...
