Gossypium herbaceum, commonly known as Levant cotton, [1] is a species of cotton native to the semi-arid regions of sub-Saharan Africa and Arabia, where it still grows perennially in the wild as a shrub.
G. herbaceum has high stems that grow 60 to 180 centimetres (2 to 6 ft) high with wide, hairy leaves. Their flowers are small and yellow with a purple center. The plant exhibits extrafloral nectaries [2] (calyculal nectaria, found on the receptacle, near the base of the calyculus).
When ripe and in warm weather, the flower capsule will burst and expose the cotton surrounding the seeds firmly. The cotton produced by this plant is short, about 25 millimetres (1 in) long and is firmly attached to the seed, which is covered in hairy down. Cotton fibres grow from the surface of the seeds and can be separated from these by hand or mechanically; the long fibres are called lint. The cotton fibres consist of nearly pure cellulose. The expected yield is 340 kilograms per hectare (300 pounds per acre). [3]
The main use of cotton lint is to produce textiles for clothing. The fibres are spun into yarns and these are woven into fabrics, in the farm or house or in factories. Cotton as a fabric is much appreciated because of its comfortable, breathable properties, its resistance[ clarification needed ] and also because it is easily stained.
The cotton plant itself has medicinal uses, and can be cultivated traditionally, in house backyards, for, e.g., women's menstrual cycle pains and irregular bleeding. It is also known to be used after birth to expel the placenta and to increase the lactation, as well as for gastrointestinal issues, such as hemorrhages and diarrhea, for nausea, fevers and headaches.[ citation needed ]
In the Levant seeds of Gossypium herbaceum were also used for food, feed or oil extraction. Cotton seeds, containing up to 20% oil and 20% proteins, are potentially highly rich as food or feed. Nevertheless, small glands present in all the plant organs of the Gossypium species, except the roots, and especially abundant in the seeds, contain toxic chemicals, in particular the polyphenolic compound gossypol. The gossypol is highly toxic to animals and is an element of the plant direct defence system against herbivorous arthropods. It can cause severe growth and development disorders in humans as well as domestic animals, particularly monogastric animals, while polygastrics are more or less tolerant. For this reason, using oil or whole seeds for human nutrition is dependent upon some way of elimination of the gossypol, through heating or other treatment. The gossypol extracted from cotton seeds has a potential use as a male contraceptive but can cause irreversible infertility after repeated use. In lab rat studies, it has been able to stop early pregnancies. [3] [4]
Cotton is a soft, fluffy staple fiber that grows in a boll, or protective case, around the seeds of the cotton plants of the genus Gossypium in the mallow family Malvaceae. The fiber is almost pure cellulose, and can contain minor percentages of waxes, fats, pectins, and water. Under natural conditions, the cotton bolls will increase the dispersal of the seeds.
Gossypium is a genus of flowering plants in the tribe Gossypieae of the mallow family, Malvaceae, from which cotton is harvested. It is native to tropical and subtropical regions of the Old and New Worlds. There are about 50 Gossypium species, making it the largest genus in the tribe Gossypieae, and new species continue to be discovered. The name of the genus is derived from the Arabic word goz, which refers to a soft substance.
Flax, also known as common flax or linseed, is a flowering plant, Linum usitatissimum, in the family Linaceae. It is cultivated as a food and fiber crop in regions of the world with temperate climates. In 2022, France produced 75% of the world's supply of flax.
Ricinus communis, the castor bean or castor oil plant, is a species of perennial flowering plant in the spurge family, Euphorbiaceae. It is the sole species in the monotypic genus, Ricinus, and subtribe, Ricininae. The evolution of castor and its relation to other species are currently being studied using modern genetic tools. It reproduces with a mixed pollination system which favors selfing by geitonogamy but at the same time can be an out-crosser by anemophily or entomophily.
Gossypol is a natural phenol derived from the cotton plant. Gossypol is a phenolic aldehyde that permeates cells and acts as an inhibitor for several dehydrogenase enzymes. It is a yellow pigment. The structure exhibits atropisomerism, with the two enantiomers having different biochemical properties.
Kenaf [etymology: Persian], Hibiscus cannabinus, is a plant in the family Malvaceae also called Deccan hemp and Java jute. Hibiscus cannabinus is in the genus Hibiscus and is native to Africa, though its exact origin is unknown. The name also applies to the fibre obtained from this plant. Kenaf is one of the allied fibres of jute and shows similar characteristics.
Cottonseed oil is cooking oil from the seeds of cotton plants of various species, mainly Gossypium hirsutum and Gossypium herbaceum, that are grown for cotton fiber, animal feed, and oil.
Textile manufacturing or textile engineering is a major industry. It is largely based on the conversion of fibre into yarn, then yarn into fabric. These are then dyed or printed, fabricated into cloth which is then converted into useful goods such as clothing, household items, upholstery and various industrial products.
Cottonseed is the seed of the cotton plant.
Datura innoxia, known as pricklyburr, recurved thorn-apple, downy thorn-apple, Indian-apple, lovache, moonflower, nacazcul, toloatzin, toloaxihuitl, tolguache or toloache, is a species of flowering plant in the family Solanaceae. It is more rarely called sacred datura, a common name which is applied more often to the closely related Datura wrightii. It is native to the Southwestern United States, Central and South America, and introduced in Africa, Asia, Australia and Europe. The scientific name is often cited as D. innoxia. When English botanist Philip Miller first described the species in 1768, he misspelled the Latin word innoxia (inoffensive) when naming it D. inoxia. The name Datura meteloides was for some time erroneously applied to some members of the species, but that name has now been abandoned.
Dipsacus fullonum, syn. Dipsacus sylvestris, is a species of flowering plant known by the common names wild teasel or fuller's teasel, although the latter name is usually applied to the cultivated variety D. fullonum var. sativus. It is native to Eurasia and North Africa, but it is known in the Americas, southern Africa, Australia and New Zealand as an introduced species.
Gossypium sturtianum, or Sturt's desert rose, is a woody shrub, closely related to cultivated cotton, found in most mainland states of Australia and the Northern Territory. It is also known as the Darling River rose, cotton rosebush and Australian cotton.
Gossypium barbadense is one of several species of cotton. It is in the mallow family. It has been cultivated since antiquity, but has been especially prized since a form with particularly long fibers was developed in the 19th century. Other names associated with this species include Sea Island, Egyptian, Pima, and extra-long staple (ELS) cotton.
Gossypium hirsutum, also known as upland cotton or Mexican cotton, is the most widely planted species of cotton in the world. Globally, about 90% of all cotton production is of cultivars derived from this species. In the United States, the world's largest exporter of cotton, it constitutes approximately 95% of all cotton production. It is native to Mexico, the West Indies, northern South America, Central America and possibly tropical Florida.
Gossypium arboreum, commonly called tree cotton, is a species of cotton native to Indian subcontinent and other tropical and subtropical regions of the Old World. There is evidence of its cultivation as long ago as the Indus Valley Civilisation of the Indus River for the production of cotton textiles. The shrub was included in Linnaeus's Species Plantarum published in 1753. The holotype was also supplied by him, which is now in the Linnean Herbarium in the Swedish Museum of Natural History.
Malva nicaeensis is a species of flowering plant in the mallow family known by the common names bull mallow and French mallow.
Crotalaria cunninghamii, also known as green birdflower, birdflower ratulpo, parrot pea or regal birdflower, is a plant of the legume family Fabaceae, named Crotalaria after the Greek word for rattle, because their seeds rattle, and cunninghamii after early 19th century botanist Allan Cunningham. Crotalaria cunninghamii is known as Mangarr to the Nyangumarta Warrarn Indigenous group.
Ipomoea lacunosa, the whitestar, white morning-glory or pitted morning-glory, is a species that belongs to the genus Ipomoea. In this genus most members are commonly referred to as "morning glories". The name for the genus, Ipomoea, has root in the Greek words ips and homoios, which translates to worm-like. This is a reference to the plant's vine-like growth. Lacunosa comes from a Latin word meaning air spaces, correlating with the venation of the leaves. Ipomoea lacunosa is native to the United States and grows annually. The flowers of this species are usually white and smaller than most other morning glories.
Lint is the common name for visible accumulations of textile fibers, hair and other materials, usually found on and around clothing. Certain materials used in the manufacture of clothing, such as cotton, linen, and wool, contain numerous, very short fibers bundled together. During the course of normal wear, these fibers may either detach or be jostled out of the weave of which they are part. This is the reason why heavily used articles such as shirts and towels become thin over time and why such particles accumulate in the lint screen of a clothes dryer.
Dysdercus cingulatus is a species of true bug in the family Pyrrhocoridae, commonly known as the red cotton stainer. It is a serious pest of cotton crops, the adults and older nymphs feeding on the emerging bolls and the cotton seeds as they mature, transmitting cotton-staining fungi as they do so.
