Lewis Leonard Forman
Lewis Leonard Forman (29 June 1929 – 16 June 1998) was a British botanist, born in London. He was an expert on spermatophytes, particularly Menispermaceae, and specialised in the plants of Southeast Asia. He graduated from the University of London in 1950 and was appointed to the staff of the Royal Botanic Gardens, Kew in 1951, serving as a senior official there from 1966 to 1989. Forman was honoured with his eponymous species: * (Euphorbiaceae) '' Glochidion formanii'' Airy Shaw * (Lauraceae) '' Litsea formanii'' Kosterm. * (Melastomataceae) '' Medinilla formanii'' Regalado * (Menispermaceae) '' Stephania formanii'' Kundu & S.Guha * (Menispermaceae) '' Tinospora formanii'' Udayan & Pradeep References External links Flora of the Darwin Region {{DEFAULTSORT:Forman, Lewis Leonard 20th-century British botanists Alumni of the University of London 1929 births 1998 deaths ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. 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 of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Tree
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, e.g., including only woody plants with secondary growth, only plants that are usable as lumber, or only plants above a specified height. But wider definitions include taller palms, tree ferns, bananas, and bamboos. Trees are not a monophyletic taxonomic group but consist of a wide variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some trees reaching several thousand years old. Trees evolved around 400 million years ago, and it is estimated that there are around three trillion mature trees in the world currently. A tree typically has many secondary branches supported cle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Irvingiaceae
Irvingiaceae is a small family of flowering plants, consisting of about 13 species; it was erected by Exell and Mendonça in 1951. The family and type genus were named after the Scottish naval surgeon, Edward George Irving.D. Gledhill. ''The Names of Plants''. Cambridge University Press, 2008.

Simaroubaceae
The Simaroubaceae, also known as the quassia family, are a small, mostly tropical, family in the order Sapindales. In recent decades, it has been subject to much taxonomic debate, with several small families being split off. A molecular phylogeny of the family was published in 2007, greatly clarifying relationships within the family. Together with chemical characteristics such as the occurrence of petroselinic acid in ''Picrasma'', in contrast to other members of the family such as ''Ailanthus'', this indicates the existence of a subgroup in the family with ''Picrasma'', ''Holacantha'', and '' Castela''. The best-known species is the temperate Chinese tree-of-heaven ''Ailanthus altissima'', which has become a cosmopolitan weed tree of urban areas and wildlands. Well-known genera in the family include the tropical ''Quassia'' and '' Simarouba''. It is known in English by the common names of the quassia family or ailanthus family.

Allantospermum Borneense
''Allantospermum borneense'' is a tree in the family Irvingiaceae. The specific epithet ' is from the Latin meaning "of Borneo".

Malesia
Malesia is a biogeographical region straddling the Equator and the boundaries of the Indomalayan and Australasian realms. It is a phytogeographical floristic region in the Paleotropical kingdom. It was first recognized as a distinct region in 1857 by Heinrich Zollinger, a Swiss botanist and explorer. The precise boundaries used to define Malesia vary. The broadly defined area used in '' Flora Malesiana'' consists of the countries of Malaysia, Singapore, Indonesia, Brunei, the Philippines, Timor-Leste and Papua New Guinea. The original definition by the World Geographical Scheme for Recording Plant Distributions (WGSRPD) covered a similar area, but New Guinea and some offshore islands were split off as Papuasia in its 2001 version. Floristic region Malesia was first recognized as a distinct floristic region in 1857 by Heinrich Zollinger, a Swiss botanist and explorer. In 1948 and 1950, Cornelius G. G.

Madagascar
Madagascar, officially the Republic of Madagascar, is an island country that includes the island of Madagascar and numerous smaller peripheral islands. Lying off the southeastern coast of Africa, it is the world's List of islands by area, fourth largest island, the List of island countries, second-largest island country, and the List of countries and dependencies by area, 46th largest country overall. Its capital and List of cities in Madagascar, largest city is Antananarivo. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from Africa during the Early Jurassic period, around 180 million years ago, and separated from the Indian subcontinent approximately 90 million years ago. This isolation allowed native plants and animals to evolve in relative seclusion; as a result, Madagascar is a biodiversity hotspot and one of the world's 17 megadiverse countries, with over 90% of its wildlife of Madagascar, wildlife being endemic.

Forest Research Institute Malaysia
The Forest Research Institute Malaysia (FRIM; Malay: ''Institut Penyelidikan Perhutanan Malaysia'') is a statutory agency of the Government of Malaysia, under the Natural Resources and Environmental Sustainability (NRES). FRIM promotes sustainable management and optimal use of forest resources in Malaysia by generating knowledge and technology through research, development and application in tropical forestry. FRIM is located in Kepong, near Kuala Lumpur. FRIM is the world's oldest and largest re-created tropical rain forest. History In 1926, the chief conservator of the forest (equivalent to today's director of forestry), G.E.S Cubitt, asked F.W. Foxworthy to establish a separate forest research unit for the Forestry Department. It was Foxworthy who selected the present site, at Kepong. He was also to become the institute's first chief research officer. The site comprised an area that was practically stripped of its original forest cover except for a few remnant trees ...
