Nepenthes Sumatrana
''Nepenthes sumatrana'' is a tropical pitcher plant endemism, endemic to the Indonesian island of Sumatra, after which it is named. Discovery and taxonomy ''Nepenthes sumatrana'' was first collected by Johannes Elias Teijsmann in February 1856, near the port town of Sibolga.Teijsmann, J.E. 1857. Dagverhaal eener botanische reis over de westkust van Sumatra. ''Natuurkundig Tijdschrift voor Nederlandsch Indië'' XIV: 249–376. Teijsmann wrote the following account of his discovery: Among the plants collected to-day and the day before yesterday [February 3rd and 1st], there were 4 species of ''Nepenthes'' (''katoepat baroek'', ''tjalong baroek'', or ''taau-taau''), growing here on the very coast between the scrub in a thin layer of humus, under which pure sea sand, or against steep rocks and the coast, when there was only some earth or moss for the germination. Some species are very common and luxuriant here and abound in flowers and fruits. The plants are all transported to Buit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Friedrich Anton Wilhelm Miquel
Friedrich Anton Wilhelm Miquel (24 October 1811 – 23 January 1871) was a Dutch botanist, whose main focus of study was on the flora of the Dutch East Indies. Early life Miquel was born in Neuenhaus and studied medicine at the University of Groningen, where, in 1833, he received his doctorate. After starting work as a doctor at the Buitengasthuis Hospital in Amsterdam, in 1835, he taught medicine at the clinical school in Rotterdam. In 1838 he became correspondent of the Royal Institute, which later became the Royal Netherlands Academy of Arts and Sciences, and in 1846 he became member. He was professor of botany at the University of Amsterdam (1846–1859) and Utrecht University (1859–1871). He directed the Rijksherbarium (National Herbarium) at Leiden from 1862. In 1866, he was elected a foreign member of the Royal Swedish Academy of Sciences. Research Miquel did research on the Taxonomy (biology), taxonomy of plants. He was interested in the flora of the Dutch Empire, speci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adolf Engler
Heinrich Gustav Adolf Engler (25 March 1844 – 10 October 1930) was a German botanist. He is notable for his work on alpha taxonomy, plant taxonomy and phytogeography, such as ''Die natürlichen Pflanzenfamilien'' (''The Natural Plant Families''), edited with Karl Anton Eugen Prantl, Karl A. E. von Prantl. Even now, his system of plant classification, the Engler system, is still used by many Herbarium, herbaria and is followed by writers of many manuals and Flora (plants), floras. It is still the only system that treats all 'plants' (in the wider sense, algae to flowering plants) in such depth. Engler published a prodigious number of taxonomic works. He used various artists to illustrate his books, notably Joseph Pohl (1864–1939), an illustrator who had served an apprenticeship as a wood-engraver. Pohl's skill drew Engler's attention, starting a collaboration of some 40 years. Pohl produced more than 33 000 drawings in 6 000 plates for ''Die naturlichen Pflanzenfamilien''. He ...

Variety (botany)
In botanical nomenclature, variety (abbreviated var.; in la, varietas) is a taxonomic rank below that of species and subspecies, but above that of form. As such, it gets a three-part infraspecific name. It is sometimes recommended that the subspecies rank should be used to recognize geographic distinctiveness, whereas the variety rank is appropriate if the taxon is seen throughout the geographic range of the species. Example The pincushion cactus, ''Escobaria vivipara'' (Nutt.) Buxb., is a wide-ranging variable species occurring from Canada to Mexico, and found throughout New Mexico below about . Nine varieties have been described. Where the varieties of the pincushion cactus meet, they intergrade. The variety ''Escobaria vivipara'' var. ''arizonica'' is from Arizona, while ''Escobaria vivipara'' var. ''neo-mexicana'' is from New Mexico. See also '' Capsicum annuum var. glabriusculum'' Definitions The term is defined in different ways by different authors. However, the I ...

Line (length)
The line (abbreviated L or l or ‴ or lin.) was a small English unit of length, variously reckoned as , , , or of an inch. It was not included among the units authorized as the British Imperial system in 1824. Size The line was not recognized by any statute of the English Parliament but was usually understood as of a barleycorn, which itself was recognized by statute as of an inch. The line was eventually decimalized as of an inch, without recourse to barleycorns. The US button trade uses the same or a similar term but defined as one-fortieth of the US-customary inch (making a button-maker's line equal to 0.635 mm). In use Botanists formerly used the units (usually as inch) to measure the size of plant parts. Linnaeus's ''Philosophia botanica'' (1751) includes the Linea in its summary of units of measurements, defining it as "Linea una Mensurae parisinae"; Stearns gives its length as 2.25 mm. Even after metrication, British botanists continued to employ tool ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sibolga
Sibolga (formerly sometimes Siboga) is a city and a port located in the natural harbor of Sibolga Bay on the west coast of North Sumatra province, in Indonesia. It is located on the western side of North Sumatra, facing the Indian Ocean and is a transit harbor to the Nias island which was hard hit during the 2004 Indian Ocean earthquake. Sibolga is also a semi-enclave within Central Tapanuli Regency, as Sibolga borders with Central Tapanuli Regency in the north, east, and south, while it borders with the Mentawai Strait in the west.

Johannes Elias Teijsmann
Johannes Elias Teijsmann (1 June 1808 – 22 June 1882) was a biologist, botanist and plant collector. He was born in Arnhem, The Netherlands. His surname is sometimes spelled ''Teysmann'', although he himself spelled it ''Teijsmann''. Teijsmann travelled to Java in 1830 as gardener of Governor General Johannes van den Bosch. He was appointed the director - ''hortulanus'' - of the 's Lands Plantentuin in Buitenzorg (now Bogor) the following year, a post he held until 1869. He took part in important botanical expeditions throughout maritime Southeast Asia. Teijsmann was also part of a Dutch fact-finding mission to Siam (presently Thailand). He is notable for the introduction of cassava plants (from the island of Bantam, near Sumatra) as a food source to alleviate famines in the then Dutch East Indies. Together with his collaborator Justus Carl Hasskarl, he introduced the cultivation of Cinchona trees (from Peru) for the production of quinine to treat malaria (ca. 1852/1854). There ...

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 ...

Endemism
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] |
Pitcher Plant
Pitcher plants are several different carnivorous plants which have modified leaves known as pitfall traps—a prey-trapping mechanism featuring a deep cavity filled with digestive liquid. The traps of what are considered to be "true" pitcher plants are formed by specialized leaves. The plants attract and drown their prey with nectar. Types The term "pitcher plant" generally refers to members of the Nepenthaceae and Sarraceniaceae families, but similar pitfall traps are employed by the monotypic Cephalotaceae and some members of the Bromeliaceae. The families Nepenthaceae and Sarraceniaceae are the most species-rich families of pitcher plants. The Nepenthaceae contains a single genus, '' Nepenthes'', containing over 100 species and numerous hybrids and cultivars. In this genus of Old World pitcher plants, the pitchers are borne at the end of tendrils that extend from the midrib of an otherwise unexceptional leaf. Old World pitcher plants are typically characterized as havin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nepenthes Longifolia
''Nepenthes longifolia'' () is a tropical pitcher plant endemic to Sumatra, where it grows at elevations of between 300 and 1100 m above sea level. The specific epithet ''longifolia'', formed from the Latin words ''longus'' (long) and ''folius'' (leaf), refers to the exceptionally large leaves of this species.Clarke, C.M. 2001. ''Nepenthes of Sumatra and Peninsular Malaysia''. Natural History Publications (Borneo), Kota Kinabalu. Botanical history The first known collection of ''N. longifolia'' was made by Willem Meijer in 1957. The specimen ''Meijer 6913'' was collected on August 24, 1957, in a sandstone region of the river Tjampo near Taram in West Sumatra, at an altitude of 500–1000 m. The plant was growing in forest on the slope of a river valley. The specimen is sheet H.L.B. 958.85111 at the National Herbarium of the Netherlands in Leiden. In 1986, Rusjdi Tamin and Mitsuru Hotta invalidly described ''Nepenthes rafflesiana'' var. ''longicirrhosa''. Charles Cl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
