Spatholirion Elegans
''Spatholirion'' is a genus of climbing or rosette (botany), rosette monocotyledonous flowering plants in the Commelinaceae, dayflower family. It is distributed from China in the north, south to Thailand, Vietnam, and northern Peninsular Malaysia. It has four to eight seeds per carpel, unlike the closely related ''Streptolirion'', which has only two, and white or purple petals. The inflorescence axis of ''Spatholirion longifolium'' and all of its branches are a bright purple, probably aiding in visual pollinator attraction. The genus was first described in 1896 by Henry Nicholas Ridley, the father of the commercial rubber industry, from plants sent to Kew Gardens from the Malay Peninsula near the border between Thailand and Malaysia. All species have a diploid chromosome number of 20. ; Species * ''Spatholirion calcicola'' K.Larsen & S.S.Larsen - Thailand * ''Spatholirion decumbens'' Fukuoka & N.Kurosaki - Thailand * ''Spatholirion elegans'' (Cherfils) C.Y.Wu - Yunnan, Vietnam * ...

Henry Nicholas Ridley
Henry Nicholas Ridley CMG (1911), MA (Oxon), FRS, FLS, F.R.H.S. (10 December 1855 – 24 October 1956) was an English botanist, geologist and naturalist who lived much of his life in Singapore. He was instrumental in promoting rubber trees in the Malay Peninsula that led to a level of rapid deforestation, instrumental in the 1926 Great Flood. For the fervour with which he pursued this work he came to be known as "Mad Ridley". Life Henry Ridley was the second son and third child born to Louisa Pole Stuart and Oliver Matthew Ridley in West Harling in Norfolk, where his father was the Rector. At the age of three his mother died and his father moved to Cobham in Kent. He studied at Tonbridge School and then went to Haileybury where his brother Stuart also studied. At Cobham, he had taken to the idea of collecting insects and he continued this at Haileybury where the school encouraged him to publish a "List of the Mammals and Coleoptera of Haileybury". The two brothers left Ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malay Peninsula
The Malay Peninsula is located in Mainland Southeast Asia. The landmass runs approximately north–south, and at its terminus, it is the southernmost point of the Asian continental mainland. The area contains Peninsular Malaysia, Southern Thailand, and the southernmost tip of Myanmar (Kawthaung District, Kawthaung). The island country of Singapore also has historical and cultural ties with the region. The Titiwangsa Mountains are part of the Tenasserim Hills system and form the backbone of the peninsula and the southernmost section of the central cordillera, which runs from Tibet through the Kra Isthmus, the peninsula's narrowest point, into the Malay Peninsula. The Strait of Malacca separates the Malay Peninsula from the Indonesian island of Sumatra, and the south coast is separated from the island of Singapore by the Straits of Johor. Etymology The Malay term ''Tanah Melayu'' is derived from the word ''Tanah'' (land) and ''Melayu'' (Malays (ethnic group), Malays), thus ...

Flora Of China
The flora of China consists of a diverse range of plant species including over 39,000 vascular plants, 27,000 species of fungi and 3000 species of bryophytes.Wu, Z. Y., P. H. Raven & D. Y. Hong, eds. 2006. Flora of China. Vol. 22 (Poaceae). Science Press, Beijing, and Missouri Botanical Garden Press, St. Louis - http://www.efloras.org/volume_page.aspx?volume_id=2022&flora_id=2 More than 30,000 plant species are native to China, representing nearly one-eighth of the world's total plant species, including thousands found nowhere else on Earth. China's land, extending over 9.6 million km, contains a variety of ecosystems and climates for plants to grow in. Some of the main climates include shores, tropical and subtropical forests, deserts, elevated plateaus and mountains. The events of the continental drift and early Paleozoic Caledonian movement also play a part in creating climatic and geographical diversity resulting in high levels of endemic vascular flora. These landscapes prov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commelinaceae Genera
Commelinaceae is a family of flowering plants. In less formal contexts, the group is referred to as the dayflower family or spiderwort family. It is one of five families in the order Commelinales and by far the largest of these with about 731 known species in 41 genera. Well known genera include ''Commelina'' (dayflowers) and ''Tradescantia'' (spiderworts). The family is diverse in both the Old World tropics and the New World tropics, with some genera present in both. The variation in morphology, especially that of the flower and inflorescence, is considered to be exceptionally high amongst the angiosperms. The family has always been recognized by most taxonomists. The APG III system of 2009 (unchanged from the APG system of 1998), also recognizes this family, and assigns it to the order Commelinales in the clade commelinids in the monocots. The family counts several hundred species of herbaceous plants. Many are cultivated as ornamentals. The stems of these plants are generall ...

Chromosome
A chromosome is a package of DNA containing part or all of the genetic material of an organism. In most chromosomes, the very long thin DNA fibers are coated with nucleosome-forming packaging proteins; in eukaryotic cells, the most important of these proteins are the histones. Aided by chaperone proteins, the histones bind to and condense the DNA molecule to maintain its integrity. These eukaryotic chromosomes display a complex three-dimensional structure that has a significant role in transcriptional regulation. Normally, chromosomes are visible under a light microscope only during the metaphase of cell division, where all chromosomes are aligned in the center of the cell in their condensed form. Before this stage occurs, each chromosome is duplicated ( S phase), and the two copies are joined by a centromere—resulting in either an X-shaped structure if the centromere is located equatorially, or a two-armed structure if the centromere is located distally; the jo ...

Diploid
Ploidy () is the number of complete sets of chromosomes in a cell, and hence the number of possible alleles for autosomal and pseudoautosomal genes. Here ''sets of chromosomes'' refers to the number of maternal and paternal chromosome copies, respectively, in each homologous chromosome pair—the form in which chromosomes naturally exist. Somatic cells, tissues, and individual organisms can be described according to the number of sets of chromosomes present (the "ploidy level"): monoploid (1 set), diploid (2 sets), triploid (3 sets), tetraploid (4 sets), pentaploid (5 sets), hexaploid (6 sets), heptaploid or septaploid (7 sets), etc. The generic term polyploid is often used to describe cells with three or more sets of chromosomes. Virtually all sexually reproducing organisms are made up of somatic cells that are diploid or greater, but ploidy level may vary widely between different organisms, between different tissues within the same organism, and at different stages in a ...
