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.

Perennial Plant
A perennial plant or simply perennial is a plant that lives more than two years. The term ('' per-'' + '' -ennial'', "through the years") is often used to differentiate a plant from shorter-lived annuals and biennials. The term is also widely used to distinguish plants with little or no woody growth (secondary growth in girth) from trees and shrubs, which are also technically perennials. Perennialsespecially small flowering plantsthat grow and bloom over the spring and summer, die back every autumn and winter, and then return in the spring from their rootstock or other overwintering structure, are known as herbaceous perennials. However, depending on the rigours of local climate (temperature, moisture, organic content in the soil, microorganisms), a plant that is a perennial in its native habitat, or in a milder garden, may be treated by a gardener as an annual and planted out every year, from seed, from cuttings, or from divisions. Tomato vines, for example, live several y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of The Bonin Islands
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms ''gut flora'' or ''skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de Phyt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cirsium
''Cirsium'' is a genus of perennial and biennial flowering plants in the Asteraceae, one of several genera known commonly as thistles. They are more precisely known as plume thistles. These differ from other thistle genera ('' Carduus'', ''Silybum'' and ''Onopordum'') in having feathered hairs to their achenes. The other genera have a pappus of simple unbranched hairs. They are mostly native to Eurasia and northern Africa, with about 60 species from North America (although several species have been introduced outside their native ranges). Thistles are known for their effusive flower heads, usually purple, rose or pink, also yellow or white. The radially symmetrical disc flowers are at the end of the branches and are visited by many kinds of insects, featuring a generalised pollination syndrome. They have erect stems and prickly leaves, with a characteristic enlarged base of the flower which is commonly spiny. The leaves are alternate, and some species can be slightly hairy. E ...

Cirsium Toyoshimae
is an extinct species of thistle in the family Asteraceae that was endemic to the Bonin Islands of Tōkyō Metropolis, Japan. Taxonomy The species was first described by Japanese botanist Gen-ichi Koidzumi in 1919. Description ''Cirsium toyoshimae'' had pale purple flowers and soft spines and was somewhat smaller than the extant ''Cirsium boninense''. It used to grow in wooded areas near the coast. Conservation status ''Cirsium toyoshimae'' is classed as extinct Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and ... on the Ministry of the Environment Red List.

Japanese Red List
The Japanese is the Japanese domestic counterpart to the IUCN Red List of Threatened Species. The national Red List is compiled and maintained by the Ministry of the Environment, alongside a separate Red List for marine organisms. Similarly drawing on the relevant scientific authorities, NGOs, and local governments, the Ministry of the Environment also prepares and publishes a that provides further information on species and habitats. The first Red List was published by the then Environmental Agency as part of the first Red Data Book in 1991; in 2020, the fifth edition of the fourth version of the Red List was published. In line with the Marine Biodiversity Conservation Strategy, decided upon by the Ministry in 2011, in 2017 the first Marine Life Red List was published, excluding species subject to international agreements, such as those within the remit of the Western and Central Pacific Fisheries Commission (WCPFC) (''e.g.'', Pacific bluefin tuna) and International Whaling C ...

Ministry Of The Environment (Japan)
The is a Cabinet-level ministry of the government of Japan responsible for global environmental conservation, pollution control, and nature conservation. The ministry was formed in 2001 from the sub-cabinet level Environmental Agency established in 1971. The Minister of the Environment is a member of the Cabinet of Japan and is chosen by the Prime Minister, usually from among members of the Diet. In March 2006, the then-Minister of the Environment Yuriko Koike, created a ''furoshiki'' cloth to promote its use in the modern world. In August 2011, the Cabinet of Japan approved a plan to establish a new energy watchdog under the Environment Ministry, and the Nuclear Regulation Authority was founded on September 19, 2012.

Tokyo Metropolitan Government
The is the government of the Tokyo Metropolis. One of the 56 prefectures of Japan, the government consists of a popularly elected governor and assembly. The headquarters building is located in the ward of Shinjuku. The metropolitan government administers the special wards, cities, towns and villages that constitute part of the Tokyo Metropolis. With a population closing in on 14 million living within its boundaries, and many more commuting from neighbouring prefectures, the metropolitan government wields significant political power within Japan.

Thistle
Thistle is the common name of a group of flowering plants characterised by leaves with sharp prickles on the margins, mostly in the family Asteraceae. Prickles can also occur all over the planton the stem and on the flat parts of the leaves. These prickles are an adaptation that protects the plant from being eaten by herbivores. Typically, an involucre with a clasping shape similar to a cup or urn subtends each of a thistle's flower heads. The comparative amount of spininess varies dramatically by species. For example, ''Cirsium heterophyllum'' has minimal spininess while ''Cirsium spinosissimum'' is the opposite. Typically, species adapted to dry environments have greater spininess. The term thistle is sometimes taken to mean precisely those plants in the tribe Cardueae (synonym: Cynareae), especially the genera '' Carduus'', ''Cirsium'', and ''Onopordum''. However, plants outside this tribe are sometimes called thistles. Biennial thistles are particularly noteworthy for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
