Rafflesia Lawangensis
''Rafflesia lawangensis'' is a species of parasitic plant in the genus '' Rafflesia''. It is exclusively found in Bukit Lawang, a small tourist village in Mount Leuser National Park, North Sumatra, Indonesia. Previously misidentified as ''Rafflesia arnoldii'', photographs taken in 2005 led to the eventual separation of ''Rafflesia lawangensis'' as a distinct species in 2010. Discovery ''Rafflesia lawangensis'' was first described in Volume 13 of the Journal ''Reinwardtia'' in 2010. The first description was written by K. Mat-Salleh, Ridha Mahyuni, Agus Susatya, and J.F. Veldkamp. The location of Bohorok, Bukit Lawang, was previously thought to be a possible habitat for ''Rafflesia'' plants, judging by similar floristic composition to the area of Lokop. Eventually, reports of ''Rafflesia'' plants in the area of Bohorok were noted, and were erroneously referred as members of ''Rafflesia arnoldii''. However, there was no physical material in herbariums, nor photographs taken of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 given ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rafflesia Arnoldii
''Rafflesia arnoldii'', the corpse flower or giant padma, is a species of flowering plant in the parasitic genus ''Rafflesia''. It is noted for producing the largest individual flower on Earth. It has a strong and unpleasant odor of decaying flesh. It is native to the rainforests of Sumatra and Borneo. Although there are some plants with larger flowering organs like the titan arum (''Amorphophallus titanum'') and talipot palm (''Corypha umbraculifera''), those are technically clusters of many flowers. ''Rafflesia arnoldii'' is one of the three national flowers in Indonesia, the other two being the white jasmine (''Jasminum sambac'') and moon orchid (''Phalaenopsis amabilis''). It was officially recognized as a national "rare flower" ( id, puspa langka) in Presidential Decree No. 4 in 1993. Taxonomy The first European to find ''Rafflesia'' was the ill-fated French explorer Louis Auguste Deschamps. He was a member of a French scientific expedition to Asia and the Pacific, deta ...

Endemic Flora Of Sumatra
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Locality (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost a ...

Tetrastigma Coriaceum
''Tetrastigma'' is a genus of plants in the grape family, Vitaceae. The plants are lianas that climb with tendrils and have palmately compound leaves. Plants are dioecious, with separate male and female plants; female flowers are characterized by their four-lobed stigmas. The species are found in subtropical and tropical regions of Asia, Malaysia, and Australia, where they grow in primary rainforest, gallery forest and monsoon forest and moister woodland. Species of this genus are notable as being the sole hosts of parasitic plants in the family Rafflesiaceae, one of which, '' Rafflesia arnoldii'', produces the largest single flower in the world. ''Tetrastigma'' is the donor species for horizontal gene transfer to '' Sapria'' and '' Rafflesia'' due to multiple gene theft events. Within the Vitaceae, ''Tetrastigma'' has long been considered closely related to ''Cayratia'' and ''Cyphostemma'' and is now placed in the tribe Cayratieae. Fossil record A fossil seed frag ...

Sumatra
Sumatra is one of the Sunda Islands of western Indonesia. It is the largest island that is fully within Indonesian territory, as well as the sixth-largest island in the world at 473,481 km2 (182,812 mi.2), not including adjacent islands such as the Simeulue, Nias, Mentawai, Enggano, Riau Islands, Bangka Belitung and Krakatoa archipelago. Sumatra is an elongated landmass spanning a diagonal northwest–southeast axis. The Indian Ocean borders the northwest, west, and southwest coasts of Sumatra, with the island chain of Simeulue, Nias, Mentawai, and Enggano off the western coast. In the northeast, the narrow Strait of Malacca separates the island from the Malay Peninsula, which is an extension of the Eurasian continent. In the southeast, the narrow Sunda Strait, containing the Krakatoa Archipelago, separates Sumatra from Java. The northern tip of Sumatra is near the Andaman Islands, while off the southeastern coast lie the islands of Bangka and Belitung, Karim ...

Rafflesia Micropylora
''Rafflesia micropylora'' is a parasitic plant species of the genus ''Rafflesia''. It is endemic to Sumatra in Indonesia. This species was named because of the small opening of its diaphragm or Glossary of botanical terms#corona, corona. This is one of the giant species of Rafflesia; the largest specimen being one found by ecologist/author Arnold Newman and his son Gandhi at Gunung Leuser, northern Sumatra in 1983, a whole year before publication of the official description. This one measured 38 in (97 cm) in width, and estimated by Newman senior to weigh 36 lbs (16.3 kg)Arnold Newman, "Tropical Rainforest", (New York: Facts on File, 1990) pp. 64-66 plus photo p.65 and an excellent photo on inside back dust cover. Unlike the bold markings of species like R. arnoldi, R. micropylora is covered with a myriad of tiny markings. The very small aperture of the corona suggests that its pollination strategy may also be quite different. References External links Parasiti ...

Rafflesia Kerrii
''Rafflesia kerrii'' is a member of the genus '' Rafflesia''. It is found in the rainforest of southern Thailand and peninsular Malaysia, with notable populations in Khao Sok National Park and Khlong Phanom National Park. Local Thai names are บัวผุด (''bua phut''), ย่านไก่ต้ม (''yan kai tom'') and บัวตูม (''bua tum''). The red flowers typically have a diameter of and smell awfully of rotten meat to attract flies for pollination. This species has some claim to being the world's largest flower, for although the average size of ''R. arnoldii'' is greater than the average ''R. kerrii'', there have been two recent specimens of R. kerrii of exceptional size: One specimen found in the Lojing Highlands of peninsular Malaysia on April 7, 2004 by Prof. Dr. Kamarudin Mat-Salleh, and Mat Ros measured in width, while another found in 2007 in Kelantan State, peninsular Malaysia by Dr. Gan Canglin measured .

Rafflesia
''Rafflesia'' () is a genus of parasitic flowering plants in the family Rafflesiaceae. The species have enormous flowers, the buds rising from the ground or directly from the lower stems of their host plants; one species has the largest flowers in the world. Plants of the World Online lists up to 41 species from this genus, all of them are found throughout Southeast Asia. Western Europeans first learned about plants of this genus from French surgeon and naturalist Louis Deschamps when he was in Java between 1791 and 1794; but his notes and illustrations, seized by the British in 1803, were not available to western science until 1861. The first British person to see one was Joseph Arnold in 1818, in the Indonesia rainforest in Bengkulu, Sumatra, after a Malay servant working for him discovered a flower and pointed it out to him. The flower, and the genus, was later named after Stamford Raffles, the leader of the expedition and the founder of the British colony of Singapore. The f ...
