Seongsan Ilchulbong
Seongsan Ilchulbong, also called ‘Sunrise Peak’, is an archetypal tuff cone formed by hydrovolcanic eruptions upon a shallow seabed about 5 thousand years ago. Situated on the eastern seaboard of Jeju Island and said to resemble a gigantic ancient castle, this tuff cone is 182 meters high, has a preserved bowl-like crater and also displays diverse inner structures resulting from the sea cliff. These features are considered to be of geologic worth, providing information on eruptive and depositional processes of hydromagmatic volcanoes worldwide as well as past volcanic activity of Seongsan Ilchulbong itself. Geological characteristics Seongsan Ilchulbong Tuff Cone was formed by Surtseyan-type hydrovolcanic activity upon a shallow seabed about 5,000 years ago when the sea level was same as the present. Most volcanic cones or ''oreum''s (Jeju dialect for volcanic cones) were formed by piles of scoria cones which are created by Hawaiian eruptions or Strombolian eruptions. ...

Taxa
In biology, a taxon ( back-formation from '' taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hallasan
Hallasan is a shield volcano on Jeju Island in South Korea; it is the highest point of South Korea and the second-highest mountain in Korea overall, after Paektu Mountain. The area around the mountain is a designated national park, the Hallasan National Park (, ). Hallasan is commonly considered to be one of the three main mountains of South Korea, along with Jirisan and Seoraksan. Names Hallasan is the highest mountain in South Korea and is worshipped by people as they believe that gods and spirits live on the mountain. Alternate English names for the mountain include Hanla Mountain or Mount Halla and older English sources refer to the peak as Mount Auckland. Hallasan is written in Hangul as if it were ''Hanrasan'' (); however, it is still pronounced as ''Hallasan''. In the past, Hallasan has been known by numerous other names in Korean including ''Buak'' (/), ''Wonsan'' (/), ''Jinsan'' (/), ''Seonsan'' (/), ''Dumuak'' (/), ''Burasan'' (/), ''Yeongjusan'' (/), and ''Hyeolman ...

Glehnia Littoralis
''Glehnia'' is a genus of plants in the carrot family, Apiaceae. It is monotypic, being represented by the single species, ''Glehnia littoralis'', commonly known as beach silvertop and American silvertop. The genus was named after Russian botanist Peter von Glehn. Description It is a long-taprooted plant forming a basal patch of leaves, with each leaf made up of several rounded, lobular segments. It reaches a maximum height exceeding , with the North American subspecies only reported to reach . The plant's erect stem is topped with an umbel of carrotlike white flowers. Chemistry The plant contains naphthisoxazole A. Taxonomy Two subspecies exist, one in Asia and one in North America; the latter is named ''leiocarpa''. Distribution and habitat It is native to eastern Asia, particularly eastern China, Japan, and far-eastern Russia, and western North America from Alaska to northern California. It can be found on sandy beaches and dunes. Uses The plant is perhaps best kno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arisaema Heterophyllum
''Arisaema heterophyllum'', the dancing crane cobra lily, belongs to the monocotyledonous flowering family Araceae. It is a perennial, rhizomatous herb native to East Asia. It has a spadix inflorescence and can be recognized by its green spathe and comparatively smaller central leaflet. The rhizome is often used in Chinese traditional medicine as a treatment for coughs, epilepsy, and tetanus. It is prepared using ginger and potassium aluminum sulphate for purifying purposes. Description The roots are tubular, depressed globose shaped, and around 2–6 cm in diameter. The usually solitary leaves are around 30–60 cm long, with glaucous petioles and sheathing adjacent to the pseudostem. They are sedately divided, adaxially dull green and abaxially pale green, and contain 4 or 5 cataphylls and multiple leaflets, ranging from 11 to 21 in number. The central leaflet is 3–15 cm long and 0.7-5.8 cm wide; the outermost leaflets are smaller. The distance between ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 par ...

Orobanche Coerulescens
''Orobanche'', commonly known as broomrape, is a genus of over 200 species of small parasitic herbaceous plants, mostly native to the temperate Northern Hemisphere. It is the type genus of the broomrape family Orobanchaceae. Description Broomrapes are generally small, only tall depending on species. They are best recognized by the yellow- to straw-coloured stems completely lacking chlorophyll, bearing yellow, white, or blue snapdragon-like flowers. The flower shoots are scaly, with a dense terminal spike of 10-20 flowers in most species, although single in one-flowered broomrape (''Orobanche uniflora''). The leaves are merely triangular scales. The seeds are minute, tan or brown, blackening with age. These plants generally flower from late winter to late spring. When they are not flowering, no part of the plants is visible above the surface of the soil. Parasitism As they have no chlorophyll, the broomrapes are totally dependent on other plants for nutrients. Broomrape seed ...

Aeginetia Indica
''Aeginetia indica'', commonly known as Indian broomrape or forest ghost flower, is a holoparasitic herb or root parasite of the plant family Orobanchaceae. It grows in moist deciduous and semi-evergreen forests of tropical and subtropical Asia and New Guinea.Aeginetia indica (forest ghost flower), Vélez-Gavilán J, 2019Invasive Species Compendium Wallingford, UK It parasitises plants of the families Cannaceae, Commelinaceae, Cyperaceae, Juncaceae, Poaceae, and Zingiberaceae. In many regions, including the Nepal Eastern Himalayas, ''Aeginetia indica'' is used for medicinal and ritual purposes. For example, the entire plant is placed in shrines or on altars during the Teej festival as a symbol of Shiva and Parvati Parvati ( sa, पार्वती, ), Uma ( sa, उमा, ) or Gauri ( sa, गौरी, ) is the Hindu goddess of power, energy, nourishment, harmony, love, beauty, devotion, and motherhood.

Parasitic Plant
A parasitic plant is a plant that derives some or all of its nutritional requirements from another living plant. They make up about 1% of angiosperms and are found in almost every biome. All parasitic plants develop a specialized organ called the haustorium, which penetrates the host plant, connecting them to the host vasculature – either the xylem, phloem, or both. For example, plants like '' Striga'' or '' Rhinanthus'' connect only to the xylem, via xylem bridges (xylem-feeding). Alternately, plants like '' Cuscuta'' and some members of ''Orobanche'' connect to both the xylem and phloem of the host. This provides them with the ability to extract water and nutrients from the host. Parasitic plants are classified depending on the location where the parasitic plant latches onto the host (root or stem), the amount of nutrients it requires, and their photosynthetic capability. Some parasitic plants can locate their host plants by detecting volatile chemicals in the air or soil gi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neofinetia Falcata
''Vanda falcata'', the wind orchid, is a species of orchid found in China, Korea, and Japan. It was formerly classified in the genus ''Neofinetia''. *风兰 (feng lan) China (N Fujian, S Gansu, SW Hubei, W Jiangxi, Sichuan, Zhejiang) *풍란 (pungnan) Korea *風蘭 (fūran) Japan (Honshu from the Kantō region westwards; Shikoku; Kyushu; and Ryukyu Islands.) Named cultivars selected for characteristics including variegation, flower color or form, and vegetative form are often referred to as 富貴蘭 (fūkiran) in Japan. Due to these highly variable mutant forms this species has been proposed as a model organism for floral development in orchids. Description Plants are 8–12 cm tall on monopodial stems of 1–6 cm. There are usually between 4 and 20 narrowly oblong-falcate (hence the epithet) leaves of 5–12 cm. that are leathery and sheathed at the base. The inflorescence, including flowers, is 5–8 cm. long, suberect, and carries as few as two, and as m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
