Chrysanthemum Rhombifolium
Chrysanthemums (), sometimes called mums or chrysanths, are flowering plants of the genus ''Chrysanthemum'' in the family Asteraceae. They are native to East Asia and northeastern Europe. Most species originate from East Asia and the center of diversity is in China.Liu, P. L., et al. (2012)Phylogeny of the genus ''Chrysanthemum'' L.: Evidence from single-copy nuclear gene and chloroplast DNA sequences.''PLOS One'' 7(11), e48970. . Countless horticultural varieties and cultivars exist. Description The genus ''Chrysanthemum'' are perennial herbaceous flowering plants, sometimes subshrubs. The leaves are alternate, divided into leaflets and may be pinnatisect, lobed, or serrate (toothed) but rarely entire. The compound inflorescence is an array of several flower heads, or sometimes a solitary head. The head has a base covered in layers of phyllaries. The simple row of ray florets is white, yellow, or red. The disc florets are yellow. Pollen grains are approximately 34 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Serrate
Serration is a saw-like appearance or a row of sharp or tooth-like projections. A serrated cutting edge has many small points of contact with the material being cut. By having less contact area than a smooth blade or other edge, the applied pressure at each point of contact is greater and the points of contact are at a sharper angle to the material being cut. This causes a cutting action that involves many small splits in the surface of the material being cut, which cumulatively serve to cut the material along the line of the blade. In nature, serration is commonly seen in the cutting edge on the teeth of some species, usually sharks. However, it also appears on non-cutting surfaces, for example in botany where a toothed leaf margin or other plant part, such as the edge of a carnation petal, is described as being serrated. A serrated leaf edge may reduce the force of wind and other natural elements. Probably the largest serrations on Earth occur on the skylines of mountains (th ...

Rhodanthemum
''Rhodanthemum'' syn. ''Chrysanthemopsis'', ''Pyrethropsis'' (Moroccan daisy), is a genus of flowering plants in the family Asteraceae, mostly native to exposed rocky places in Northern Africa (Morocco and Algeria). Formerly included in either '' Chrysanthemum'' or ''Leucanthemum'', the 10 or 15 species of ''Rhodanthemum'' display many similarities to their former congeners, with composite daisy-like flowers. They are mat-forming, prostrate perennials or subshrubs, and some are cultivated as ornamental plants. The botanical name comes from the Greek ''ῥόδον'' (rose) + ''ἄνθεμον'' (flower). Species The International Plant Names Index The International Plant Names Index (IPNI) describes itself as "a database of the names and associated basic bibliographical details of seed plants, ferns and lycophytes."

Leucanthemum
''Leucanthemum'' is a genus of flowering plants in the aster family, Asteraceae. It is mainly distributed in southern and central Europe. Some species are known on other continents as introduced species, and some are cultivated as ornamental plants. The name ''Leucanthemum'' derives from the Greek words ''λευκός – leukos'' ("white") and ''ἄνθεμον – anthemon'' ("flower"). Common names for ''Leucanthemum'' species usually include the name daisy (e.g. ox-eye daisy, Shasta daisy), but "daisy" can also refer to numerous other genera in the Asteraceae family. Description ''Leucanthemum'' species are perennial plants growing from red-tipped rhizomes. The plant produces one erect stem usually reaching 40 to 130 centimeters tall, but known to exceed 2 meters at times. It is branching or unbranched and hairy to hairless. Some species have mainly basal leaves, and some have leaves along the stem, as well. Some leaves are borne on petioles, and others are sessile, attach ...

Glebionis
''Glebionis'' is a small genus of flowering plants in the family Asteraceae, native to Europe and the Mediterranean region. The species were formerly treated in the genus '' Chrysanthemum'', but a 1999 ruling of the International Botanical Congress has resulted in that genus being redefined to cover the species related to the economically important florist's chrysanthemum, thereby excluding the species now included in ''Glebionis''. ''Glebionis'' species have been hybridized with related '' Argyranthemum'' species to create cultivars of garden marguerites. ;Species *''Glebionis coronaria'' (syn.

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

International Botanical Congress
International Botanical Congress (IBC) is an international meeting of botanists in all scientific fields, authorized by the International Association of Botanical and Mycological Societies (IABMS) and held every six years, with the location rotating between different continents. The current numbering system for the congresses starts from the year 1900; the XVIII IBC was held in Melbourne, Australia, 24–30 July 2011, and the XIX IBC was held in Shenzhen, China, 23–29 July 2017. The IBC has the power to alter the ICN ( International Code of Nomenclature for algae, fungi, and plants), which was renamed from the International Code of Botanical Nomenclature (ICBN) at the XVIII IBC. Formally the power resides with the Plenary Session; in practice this approves the decisions of the Nomenclature Section. The Nomenclature Section meets before the actual Congress and deals with all proposals to modify the Code: this includes ratifying recommendations from sub-committees on conservation. ...

Botanical Authority
In botanical nomenclature, author citation is the way of citing the person or group of people who validly published a botanical name, i.e. who first published the name while fulfilling the formal requirements as specified by the '' International Code of Nomenclature for algae, fungi, and plants'' (''ICN''). In cases where a species is no longer in its original generic placement (i.e. a new combination of genus and specific epithet), both the authority for the original genus placement and that for the new combination are given (the former in parentheses). In botany, it is customary (though not obligatory) to abbreviate author names according to a recognised list of standard abbreviations. There are differences between the botanical code and the normal practice in zoology. In zoology, the publication year is given following the author names and the authorship of a new combination is normally omitted. A small number of more specialized practices also vary between the recommendations ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Achene
An achene (; ), also sometimes called akene and occasionally achenium or achenocarp, is a type of simple dry fruit produced by many species of flowering plants. Achenes are monocarpellate (formed from one carpel) and indehiscent (they do not open at maturity). Achenes contain a single seed that nearly fills the pericarp, but does not adhere to it. In many species, what is called the "seed" is an achene, a fruit containing the seed. The seed-like appearance is owed to the hardening of the fruit wall (pericarp), which encloses the solitary seed so closely as to seem like a seed coat. Examples The fruits of buttercup, buckwheat, caraway, quinoa, amaranth, and cannabis are typical achenes. The achenes of the strawberry are sometimes mistaken for seeds. The strawberry is an accessory fruit with an aggregate of achenes on its outer surface, and what is eaten is accessory tissue. A rose produces an aggregate of achene fruits that are encompassed within an expanded hypanthium (aka f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
