Lasia Spinosa
''Lasia'' is a genus of flowering plants in the family Araceae, native to Asia and New Guinea. The genus contains only two known species, ''Lasia spinosa'' and ''Lasia concinna''. ''Lasia'' was believed to be a monotypic genus until 1997 when a wild population of ''Lasia concinna'' was discovered in a farmer's paddy field in West Kalimantan, Indonesia. The farmer had been growing them for their edible young leaves. This species of ''Lasia'' had been known of previously only from a single specimen at the Bogor Botanic Gardens, formally described in 1920. Prior to 1997, the specimen was believed to have been a hybrid between ''Lasia spinosa'' and ''Cyrtosperma merkusii''. The subsequent discovery by Hambali and Sizemore led to the realization that it was in fact a distinct species.

João De Loureiro
João de Loureiro (1717, Lisbon – 18 October 1791) was a Portuguese Jesuit missionary and botanist. Biography After receiving admission to the Jesuit Order, João de Loureiro served as a missionary in Goa, capital of Portuguese India (3 years) and Macau (4 years). In 1742 he traveled to Cochinchina, remaining there for 35 years. Here he worked as a mathematician and naturalist for the king of Cochinchina, acquiring knowledge on the properties and uses of native medicinal plants. In 1777, he journeyed to Canton, in Bengal, returning to Lisbon four years later. During this period, the Captain Thomas Riddel gave Loureiro the books ''Systema Naturae'', ''Genera Plantarum'' and ''Philosophia Botanica'' by Carl Linnaeus, which greatly influenced the Portuguese botanist. The first 40 years he stayed in Vietnam, João de Loureiro was inventorying indigenous herbal remedies. His local garden contained 1,000 unique herbal species, making him one of the greatest botanist collectors o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paddy Field
A paddy field is a flooded field (agriculture), field of arable land used for growing Aquatic plant, semiaquatic crops, most notably rice and taro. It originates from the Neolithic rice-farming cultures of the Yangtze River basin in southern China, associated with Austronesian peoples#Neolithic China, pre-Austronesian and Hmong–Mien languages, Hmong-Mien cultures. It was spread in prehistoric times by the Austronesian peoples#Austronesian expansion, expansion of Austronesian peoples to Island Southeast Asia, Southeast Asia including Northeastern India, Madagascar, Melanesia, Micronesia, and Polynesia. The technology was also acquired by other cultures in mainland Asia for rice farming, spreading to East Asia, Mainland Southeast Asia, and South Asia. Fields can be built into steep hillsides as Terrace (agriculture), terraces or adjacent to depressed or steeply sloped features such as rivers or marshes. They require a great deal of labor and materials to create and need l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cyrtosperma Merkusii
''Cyrtosperma merkusii'' or giant swamp taro, is a crop grown throughout Oceania and into South and Southeast Asia. It is a riverine and "swamp crop" similar to taro, but "with bigger leaves and larger, coarser roots." There are no demonstrably wild populations today, but it is believed to be native to Indonesia. It is known as ''puraka'' in Cook Islands, ''lak'' in Yap (Federated States of Micronesia), ''babai'' in Kiribati, ''iaraj'' in the Marshall Islands, ''brak'' in Palau, ''baba'' in the Marianas Islands, ''pula’a'' in Samoa, ''via kana'', Pulaka in Lau, Lovo in Fiji, ''pulaka'' in Tokelau and Tuvalu, ''mwahng'' in Pohnpei, ''pasruk'' in Kosrae, ''simiden'' in Chuuk, ''swam taro'' in Papua New Guinea, ''navia'' in Vanuatu and ''palawan'' in the Philippines. The same species is also known by the names ''Cyrtosperma lasioides'', ''Cyrtosperma chamissonis'' and ''Cyrtosperma edule''.

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bogor Botanical Gardens
The Bogor Botanical Gardens ( id, Kebun Raya Bogor) is a botanical garden located in Bogor, Indonesia, 60 km south of central Jakarta. It is currently operated by Indonesian Institute of Sciences (Indonesian: ''Lembaga Ilmu Pengetahuan Indonesia'' or LIPI). The garden is located in the city center and adjoin the presidential palace compound of Istana Bogor. It covers an area of and contains 13,983 different kinds of trees and plants of various origin. The geographic position of Bogor means it rains almost daily, even in the dry season. This makes the garden an advantageous location for the cultivation of tropical plants. Founded in 1817 by the order of the government of the Dutch East Indies, the garden thrived under the leadership of many renowned botanists including Johannes Elias Teijsmann, Rudolph Herman Christiaan Carel Scheffer, and Melchior Treub. Since its foundation, the Bogor botanical garden has served as a major research center for agriculture and horticulture. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda. ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...
