Acer Morifolium
''Acer morifolium'', the mulberry-leaf maple, is a species of flowering plant in the family Sapindaceae. It is endemic to the island of Yakushima, Japan. A tree reaching , it is found in forests from sea level up to the highest point on the island; . As its common and scientific names suggest, its leaves are very unlike most maples, and instead resemble the unlobed leaves of mulberries. Although rare in commerce, and confined to a island in the wild, it is assessed as Least Concern A least-concern species is a species that has been evaluated and categorized by the International Union for Conservation of Nature (IUCN) as not being a focus of wildlife conservation because the specific species is still plentiful in the wil ....

Gen-ichi Koidzumi
was a Japanese botanist, author of several papers and monographs on phytogeography including work on roses and Amygdaloideae (Rosaceae), maples (Aceraceae), mulberries (the genus '' Morus''), and many other plants. His name is sometimes transliterated as Gen’ichi or Gen-Iti, or as Koizumi. Biography Gen-ichi Koidzumi was born in Yonezawa in Yamagata Prefecture in 1883. After graduating from the Sapporo Agricultural College, he studied biology at Tokyo Imperial University from 1905, continuing his studies there under Matsumura Jinzō, and receiving his doctorate in 1916. In 1919, he was appointed assistant professor at Kyoto Imperial University, where he remained (other than for a tour of the herbaria of Europe and the United States from 1925 to 1927) until his retirement in 1943; he was promoted to full professor in 1936. In 1932, he founded the Societas Phytogeographica and the journal '' Acta Phytotaxonomica et Geobotanica''. Koidzumi died in his hometown of Yonezawa in 19 ...

Sapindaceae
The Sapindaceae are a family (biology), family of flowering plants in the order Sapindales known as the soapberry family. It contains 138 genera and 1,858 accepted species. Examples include Aesculus, horse chestnut, maples, ackee and lychee. The Sapindaceae occur in temperate to tropical regions, many in laurel forest habitat, throughout the world. Many are Glossary of botanical terms#laticiferous, laticiferous, i.e. they contain latex, a milky sap, and many contain mildly Toxicity, toxic saponins with soap-like qualities in either the foliage and/or the seeds, or roots. The largest genera are ''Serjania'', ''Paullinia'', ''Allophylus'' and ''Maple, Acer''. Description Plants of this family have a variety of habits, from trees to herbaceous plants to lianas. The leaves of the tropical genera are usually spirally alternate, while those of the temperate maples (''Maple, Acer), Aesculus'', and a few other genera are opposite. They are most often leaf shape, pinnately compound, but a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yakushima
is one of the Ōsumi Islands in Kagoshima Prefecture, Japan. The island, in area, has a population of 13,178. It is accessible by hydrofoil ferry, car ferry, or by air to Yakushima Airport. Administratively, the island consists of the town of Yakushima, which extends to the neighbouring island of Kuchinoerabujima. 42% of the island is within the borders of the Yakushima National Park. Yakushima's electricity is more than 50% hydroelectric, and surplus power has been used to produce hydrogen gas in an experiment by Kagoshima University. The island has been a test site for Honda's hydrogen fuel cell vehicle research. World Heritage designation In 1980, an area of was designated a UNESCO Man and the Biosphere Reserve. In 1993, of wetland at Nagata-hama was designated a Ramsar site. Yakushima is the largest nesting ground for the endangered loggerhead sea turtle in the North Pacific. The island's unique remnant of warm/temperate ancient forest has been a natural World ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mulberries
''Morus'', a genus of flowering plants in the family Moraceae, consists of 19 species of deciduous trees commonly known as mulberries, growing wild and under cultivation in many temperate world regions. Generally, the genus has 64 subordinate taxa, though the three most common are referred to as white, red, and black, originating from the color of their dormant buds and not necessarily the fruit color (''Morus alba'', '' M. rubra'', and '' M. nigra'', respectively), with numerous cultivars and some taxa currently unchecked and awaiting taxonomic scrutiny. ''M. alba'' is native to South Asia, but is widely distributed across Europe, Southern Africa, South America, and North America. ''M. alba'' is also the species most preferred by the silkworm. It is regarded as an invasive species in Brazil, the United States and some states of Australia. The closely related genus ''Broussonetia'' is also commonly known as mulberry, notably the paper mulberry (''Broussonet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Least Concern
A least-concern species is a species that has been evaluated and categorized by the International Union for Conservation of Nature (IUCN) as not being a focus of wildlife conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the " Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15,636) in the IUCN database still use the code "LR/lc", which indicates they have not been re- ...

Maple
''Acer'' is a genus of trees and shrubs commonly known as maples. The genus is placed in the soapberry family Sapindaceae.Stevens, P. F. (2001 onwards). Angiosperm Phylogeny Website. Version 9, June 2008 nd more or less continuously updated since http://www.mobot.org/MOBOT/research/APweb/. There are approximately 132 species, most of which are native to Asia, with a number also appearing in Europe, northern Africa, and North America. Only one species, '' Acer laurinum'', extends to the Southern Hemisphere.Gibbs, D. & Chen, Y. (2009The Red List of Maples Botanic Gardens Conservation International (BGCI) The type species of the genus is the sycamore maple ''Acer pseudoplatanus'', one of the most common maple species in Europe.van Gelderen, C.

Endemic Flora Of Japan
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...
