Field Thistle
''Cirsium discolor'', the field thistle, is a North American species of plants in the tribe Cardueae within the family Asteraceae. It is native to thirty-three states in the United States as well four Canadian provinces. It occurs across much of eastern and central Canada as well as eastern and central United States. It has been found from New Brunswick west to Saskatchewan and south as far as Texas and Georgia (U.S. state), Georgia. Field thistle is a biennial or perennial herb up to tall, producing a large taproot. There is usually only one stem with numerous spiny leaves that are green on the upper side but white and woolly underneath. The plant's flower heads are large and showy and have the pale to medium value purplish magenta coloration (lilac, lavender, pinkish purple, purplish pink) that is especially attractive to butterflies. The same color can be seen in the flowers of the genus ''Liatris'', among many others. Heads have many disc florets but no ray florets. The speci ...

Ray Florets
Asteraceae () is a large family of flowering plants that consists of over 32,000 known species in over 1,900 genera within the order Asterales. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. The Asteraceae were first described in the year 1740 and given the original name Compositae. The family is commonly known as the aster, daisy, composite, or sunflower family. Most species of Asteraceae are herbaceous plants, and may be annual, biennial, or perennial, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions, in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. Their common primary characteristic is compound flower heads, technically known as capitula, consisting of sometimes hundreds ...

Cirsium
''Cirsium'' is a genus of Perennial plant, perennial and Biennial plant, 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 a seed with a Pappus (flower structure), pappus of feathered hairs on 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). The type (biology), lectotype species of the genus is ''Cirsium heterophyllum'' (L.) Hill. ''Cirsium'' 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. Th ...

Cheese
Cheese is a type of dairy product produced in a range of flavors, textures, and forms by coagulation of the milk protein casein. It comprises proteins and fat from milk (usually the milk of cows, buffalo, goats or sheep). During production, milk is usually acidified and either the enzymes of rennet or bacterial enzymes with similar activity are added to cause the casein to coagulate. The solid curds are then separated from the liquid whey and pressed into finished cheese. Some cheeses have aromatic molds on the rind, the outer layer, or throughout. Over a thousand types of cheese exist, produced in various countries. Their styles, textures and flavors depend on the origin of the milk (including the animal's diet), whether they have been pasteurised, the butterfat content, the bacteria and mold, the processing, and how long they have been aged. Herbs, spices, or wood smoke may be used as flavoring agents. Other added ingredients may include black pepper, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rennin
Chymosin or rennin is a protease found in rennet. It is an aspartic endopeptidase belonging to MEROPS A1 family. It is produced by newborn ruminant animals in the lining of the abomasum to curdle the milk they ingest, allowing a longer residence in the bowels and better absorption. It is widely used in the production of cheese. Historically, chymosin was obtained by extracting it from the stomachs of slaughtered calves. Today, most commercial chymosin used in cheese production is produced recombinantly in , ''Aspergillus niger'' var. ''awamori'', and . Occurrence Chymosin is found in a wide range of tetrapods, although it is best known to be produced by ruminant animals in the lining of the abomasum. Chymosin is produced by gastric chief cells in newborn mammals to curdle the milk they ingest, allowing a longer residence in the bowels and better absorption. Non-ruminant species that produce chymosin include pigs, cats, seals,Staff, Online Mendelian Inheritance in Man (O ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bull Thistle
''Cirsium vulgare'', commonly known as spear thistle, bull thistle, or common thistle, is a species of the Asteraceae genus ''Cirsium'', native throughout most of Europe (north to 66°N, locally 68°N), Western Asia (east to the Yenisei Valley), and North Africa, northwestern Africa (Atlas Mountains).''Flora Europaea''''Cirsium vulgare''/ref> It is also naturalisation (biology), naturalised in North America, Africa, and Australia and is an invasive species, invasive weed in several regions. It is the national flower of Scotland. The plant provides a great deal of nectar for pollinators. It was rated in the top 10 for most nectar production (nectar per unit cover per year) in a UK plants survey conducted by the AgriLand project which is supported by the UK Insect Pollinators Initiative. Marsh thistle, ''Cirsium palustre'', was ranked in first place while this thistle was ranked in sixth place. It also was a top producer of nectar sugar in another study in Britain, ranked third wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cardueae
The Cardueae are a tribe (biology), tribe of flowering plants in the daisy family (Asteraceae) and the subfamily Carduoideae. Most of them are commonly known as thistles; four of the best known genera are ''Carduus'', ''Cynara'' (containing the widely eaten artichoke), ''Cirsium'', and ''Onopordum''. They are annual plant, annual, biennial plant, biennial, or perennial plant, perennial Herbaceous plant, herbs. Many species are thorn (botany), thorny on leaves, stems, or Involucral bract, involucre, and some have latex, laticifers or resin conduits. Almost 80 genera comprising 2500 species are assigned to this tribe, native of temperate regions of Europe and Asia (especially the Mediterranean region and Minor Asia), Australia and tropical Africa; only three genera contain species native to the Americas.Bremer 1994 ''Asteraceae'': Cladistic and Classification [Tribe ''Carduae'': 112-156] Taxonomy The correct name for the tribe has been disputed.

Liatris
''Liatris'' (), commonly known as gayfeather and blazing star is a genus of flowering plants in the tribe Eupatorieae within the family Asteraceae native to North America (Canada, United States, Mexico and the Bahamas). Some species are used as ornamental plants, sometimes in flower bouquets. They are perennials, surviving the winter and resprouting from underground corms. ''Liatris'' species are used as food plants by the larvae of some Lepidoptera species such as moths of the genus ''Schinia''. Classification ''Liatris'' is in the tribe Eupatorieae of the aster family. Like other members of this tribe, the flower heads have disc florets and no ray florets. ''Liatris'' is in the subtribe Liatrinae along with '' Trilisa'', '' Carphephorus'', and other genera. ''Liatris'' is closely related to ''Garberia'', a genus with only one species endemic to Florida. The two genera can be distinguished by the shrub form of the latter and by karyotype.
