An aril called an arillus, is a specialized outgrowth from a seed that or covers the seed. An arillode or false aril is sometimes distinguished: whereas an aril grows from the attachment point of the seed to the ovary, an arillode forms from a different point on the seed coat; the term "aril" is sometimes applied to any fleshy appendage of the seed in flowering plants, such as the mace of the nutmeg seed. Arils and arillodes are edible enticements that encourage animals to transport the seed, thereby assisting in seed dispersal. Pseudarils are aril-like structures found on the pyrenes of Burseraceae species that develop from the mesocarp of the ovary; the fleshy, edible pericarp splits neatly in two halves falling away or being eaten to reveal a brightly coloured pseudaril around the black seed. The aril may create a fruit-like structure, called a false fruit. False fruit are found in numerous Angiosperm taxa; the edible false of the longan and ackee fruits are developed arils surrounding the seed rather than a pericarp layer.
Such arils are found in a few species of gymnosperms, notably the yews and related conifers such as the lleuque and the kahikatea. Instead of the woody cone typical of most gymnosperms, the reproductive structure of the yew consists of a single seed that becomes surrounded by a fleshy, cup-like covering; this covering is derived from a modified cone scale. In European yew plants, the aril starts out as a small, green band at the base of the seed turns brown to red as it enlarges and surrounds the seed becoming fleshy and scarlet in color at maturity; the aril is non-toxic. All other parts of the yew are toxic, including the seed housed inside the aril. If the seed is crushed, breaks or splits in the stomach of a human, bird or another animal, it will result in poisoning. Birds digest the fleshy aril as a food source, pass the seeds out in their droppings, promoting dispersal of the seeds; the kahikatea tree, Dacrycarpus dacrydioides, is native to New Zealand. In pre-European times the aril of the kahikatea was a food source for Māori.
The washed arils were eaten raw. Elaiosome Sarcotesta, a fleshy epidermal layer of a seed coat, as in pomegranate Anderson, E. & Owens, J. N.. Analysing the reproductive biology of Taxus: should it be included in Coniferales? Acta Hort. 615: 233–234
The Magnoliales comprise an order of flowering plants. The Magnoliales include six families: Annonaceae Degeneriaceae Eupomatiaceae Himantandraceae Magnoliaceae Myristicaceae The APG system, APG II system, APG III system place this order in the clade magnoliids, circumscribed as follows: In these systems, published by the APG, the Magnoliales are a basal group, excluded from the eudicots; the Cronquist system placed the order in the subclass Magnoliidae of class Magnoliopsida and used this circumscription: order Magnoliales family Annonaceae family Austrobaileyaceae family Canellaceae family Degeneriaceae family Eupomatiaceae family Himantandraceae family Lactoridaceae family Magnoliaceae family Myristicaceae family WinteraceaeThe Thorne system placed the order in superorder Magnolianae, subclass Magnoliidae, in the class Magnoliopsida and used this circumscription: order Magnoliales family Amborellaceae family Annonaceae family Aristolochiaceae family Austrobaileyaceae family Calycanthaceae family Canellaceae family Chloranthaceae family Degeneriaceae family Eupomatiaceae family Gomortegaceae family Hernandiaceae family Himantandraceae family Illiciaceae family Lactoridaceae family Lauraceae family Magnoliaceae family Monimiaceae family Myristicaceae family Piperaceae family Saururaceae family Schisandraceae family Trimeniaceae family WinteraceaeThe Engler system, in its update of 1964, placed the order in subclassis Archychlamydeae in class Dicotyledoneae and used this circumscription: order Magnoliales family Amborellaceae family Annonaceae family Austrobaileyaceae family Calycanthaceae family Canellaceae family Cercidiphyllaceae family Degeneriaceae family Eupomatiaceae family Eupteleaceae family Gomortegaceae family Hernandiaceae family Himantandraceae family Illiciaceae family Lauraceae family Magnoliaceae family Monimiaceae family Myristicaceae family Schisandraceae family Trimeniaceae family Tetracentraceae family Trochodendraceae family WinteraceaeThe Wettstein system, latest version published in 1935, did not use this name although it had an order with a similar circumscription with the name Polycarpicae.
This was placed in the Dialypetalae in subclass Choripetalae of class Dicotyledones.. From the above it will be clear that the plants included in this order by APG have always been seen as related, they have always been placed in the order Magnoliales. The difference is that earlier systems have included other plants, which have been moved to neighbouring orders by APG
Guangdong is a province in South China, on the South China Sea coast. Guangdong surpassed Henan and Shandong to become the most populous province in China in January 2005, registering 79.1 million permanent residents and 31 million migrants who lived in the province for at least six months of the year. This makes it the most populous first-level administrative subdivision of any country outside of South Asia, as its population is surpassed only by those of the Pakistani province of Punjab and the Indian states of Bihar and Uttar Pradesh; the provincial capital Guangzhou and economic hub Shenzhen are among the most populous and important cities in China. The population increase since the census has been modest, the province registering 108,500,000 people in 2015. Most of the historical Guangdong Province is administered by the People's Republic of China. However, the archipelagos of Pratas in the South China Sea are controlled by the Republic of China, were part of Guangdong Province before the Chinese Civil War.
Since 1989, Guangdong has topped the total GDP rankings among all provincial-level divisions, with Jiangsu and Shandong second and third in rank. According to state statistics, Guangdong's GDP in 2017 reached 1.42 trillion US dollars, making its economy the same size as Mexico. The province contributes 12% of the PRC's national economic output, is home to the production facilities and offices of a wide-ranging set of Chinese and foreign corporations. Guangdong hosts the largest import and export fair in China, the Canton Fair, hosted in the provincial capital of Guangzhou. "Guǎng" means "wide" or "vast", has been associated with the region since the creation of Guang Prefecture in AD 226. The name "Guang" came from Guangxin, an outpost established in Han dynasty near modern Wuzhou, whose name is a reference to an order by Emperor Wu of Han to "widely bestow favors and sow trust". Together and Guangxi are called Loeng gwong During the Song dynasty, the Two Guangs were formally separated as Guǎngnán Dōnglù and Guǎngnán Xīlù, which became abbreviated as Guǎngdōng Lù and Guǎngxī Lù. "Canton", though etymologically derived from Cantão, refers only to the provincial capital instead of the whole province, as documented by authoritative English dictionaries.
The local people of the city of Guangzhou and their language are called Cantonese in English. Because of the prestige of Canton and its accent, Cantonese sensu lato can be used for the phylogenetically related residents and Chinese dialects outside the provincial capital; the Neolithic era began in the Pearl River Delta 7,000 years before present, with the early period from around 7000 to 5000 BP, the late period from about 5000 to 3500 BP. In coastal Guangdong, the Neolithic was introduced from the middle Yangtze River area. In inland Guangdong, the neolithic appeared in Guangdong 4,600 years before present; the Neolithic in northern inland Guangdong is represented by the Shixia culture, which occurred from 4600–4200 BP. Inhabited by a mixture of tribal groups known to the Chinese as the Baiyue, the region first became part of China during the Qin dynasty. Under the Qin Dynasty, Chinese administration began and along with it reliable historical records in the region. After establishing the first unified Chinese empire, the Qin expanded southwards and set up Nanhai Commandery at Panyu, near what is now part of Guangzhou.
The region was a independent kingdom as Nanyue between the fall of Qin and the reign of Emperor Wu of Han. The Han dynasty administered Guangdong and northern Vietnam as Jiaozhi Province, southernmost Jiaozhi Province was used as a gateway for traders from the west—as far away as the Roman Empire. Under the Wu Kingdom of the Three Kingdoms period, Guangdong was made its own province, the Guang Province, in 226 CE; as time passed, the demographics of what is now Guangdong shifted to Chinese dominance as the populations intermingled due to commerce along the great canals, abruptly shifted through massive migration from the north during periods of political turmoil and nomadic incursions from the fall of the Han dynasty onwards. For example, internal strife in northern China following the rebellion of An Lushan resulted in a 75% increase in the population of Guangzhou prefecture between the 740s–750s and 800s–810s; as more migrants arrived, the local population was assimilated to Han Chinese culture or displaced.
Together with Guangxi, Guangdong was made part of Lingnan Circuit, or Mountain-South Circuit, in 627 during the Tang dynasty. The Guangdong part of Lingnan Circuit was renamed Guangnan East Circuit guǎng nán dōng lù in 971 during the Song dynasty. "Guangnan East" is the source of the name "Guangdong". As Mongols from the north engaged in their conquest of China in the 13th century, the Southern Song court fled southwards from its capital in Hangzhou; the defeat of the Southern Song court by Mongol naval forces in The Battle of Yamen 1279 in Guangdong marked the end of the Southern Song dynasty. During the Mongol Yuan dynas
Flora of China
The flora of China is diverse. More than 30,000 plant species are native to China, representing nearly one-eighth of the world's total plant species, including thousands found nowhere else on Earth. China contains a variety of forest types. Both northeast and northwest reaches contain mountains and cold coniferous forests, supporting animal species which include moose and Asiatic black bear, along with some 120 types of birds. Moist conifer forests can have thickets of bamboo as an understorey, replaced by rhododendrons in higher montane stands of juniper and yew. Subtropical forests, which dominate central and southern China, support an astounding 146,000 species of flora. Tropical rainforest and seasonal rainforests, though confined to Yunnan and Hainan Island, contain a quarter of all the plant and animal species found in China; the flora of China has an online database which gives both its taxonomy.

Nutmeg is the seed or ground spice of several species of the genus Myristica. Myristica fragrans is a dark-leaved evergreen tree cultivated for two spices derived from its fruit: nutmeg, from its seed, mace, from the seed covering, it is a commercial source of an essential oil and nutmeg butter. The California nutmeg, Torreya californica, has a seed of similar appearance, but is not related to Myristica fragans, is not used as a spice. If consumed in amounts exceeding its typical use as a spice, nutmeg powder may produce allergic reactions, cause contact dermatitis, or have psychoactive effects. Although used in traditional medicine for treating various disorders, nutmeg has no known medicinal value. Nutmeg is the spice made by grinding the seed of the fragrant nutmeg tree into powder; the spice has a distinctive pungent fragrance and a warm sweet taste. The seeds are dried in the sun over a period of six to eight weeks. During this time the nutmeg shrinks away from its hard seed coat until the kernels rattle in their shells when shaken.
The shell is broken with a wooden club and the nutmegs are picked out. Dried nutmegs are grayish brown ovals with furrowed surfaces; the nutmegs are egg-shaped, about 20.5–30 mm long and 15–18 mm wide, weighing 5–10 g dried. Two other species of genus Myristica with different flavors, M. malabarica and M. argentea, are sometimes used to adulterate nutmeg as a spice. Mace is the spice made from the reddish seed covering of the nutmeg seed, its flavour is more delicate. In the processing of mace, the crimson-colored aril is removed from the nutmeg seed that it envelops and is flattened out and dried for 10 to 14 days, its color changes to pale orange, or tan. Whole dry mace consists of flat pieces—smooth and brittle—about 40 mm long; the most important commercial species is the common, true or fragrant nutmeg, Myristica fragrans, native to the Banda Islands in the Moluccas of Indonesia. It is cultivated on Penang Island in Malaysia, in the Caribbean in Grenada, in Kerala, a state known as Malabar in ancient writings as the hub of spice trading, in southern India.
In the 17th-century work Hortus Botanicus Malabaricus, Hendrik van Rheede records that Indians learned the usage of nutmeg from the Indonesians through ancient trade routes. Nutmeg trees are dioecious plants and asexually. Sexual propagation yields 50 % male seedlings; as there is no reliable method of determining plant sex before flowering in the sixth to eighth year, sexual reproduction bears inconsistent yields, grafting is the preferred method of propagation. Epicotyl grafting, approach grafting, patch budding have proved successful, with epicotyl grafting being the most adopted standard. Air layering is an alternative though not preferred method because of its low success rate; the first harvest of nutmeg trees takes place seven to nine years after planting, the trees reach full production after twenty years. Nutmeg and mace have similar sensory qualities, with nutmeg having a sweeter and mace a more delicate flavour. Mace is preferred in light dishes for the bright orange, saffron-like hue it imparts.
Nutmeg is used for flavouring many dishes, nowadays is found in Western supermarkets in ground or grated form. Whole nutmeg can be ground at home using a grater designed for nutmeg. In Indonesian cuisine, nutmeg is used in various dishes in many spicy soups, such as some variant of soto, oxtail soup, sup iga and sup kambing, it is used in gravy for meat dishes, such as semur beef stew, ribs with tomato, European derived dishes such as bistik and bistik lidah. In Indian cuisine, nutmeg is used in many sweet, as well as savoury, dishes. In Kerala Malabar region, grated nutmeg is used in meat preparations and sparingly added to desserts for the flavour, it may be used in small quantities in garam masala. Ground nutmeg is smoked in India. In traditional European cuisine and mace are used in potato dishes and in processed meat products, it is commonly used in rice pudding. In Dutch cuisine, nutmeg is added to vegetables such as Brussels sprouts and string beans. Nutmeg is a traditional ingredient in mulled cider, mulled wine, eggnog.
In Scotland and nutmeg are both ingredients in haggis. In Italian cuisine, nutmeg is used as part of the stuffing for many regional meat-filled dumplings like tortellini, as well as for the traditional meatloaf. Nutmeg is a common spice for pumpkin pie and in recipes for other winter squashes, such as baked acorn squash. In the Caribbean, nutmeg is used in drinks, such as the Bushwacker and Barbados rum punch, it is a sprinkle on top of the drink. The pericarp is used to make jam, or is finely sliced, cooked with sugar, crystallised to make a fragrant candy. Sliced nutmeg fruit flesh is made as manisan, either wet, seasoned in sugary syrup liquid, or dry coated with sugar, a dessert called manisan pala in Indonesia. In Penang cuisine, dried, sh
In botany, the petiole is the stalk that attaches the leaf blade to the stem. Outgrowths appearing on each side of the petiole in some species are called stipules. Leaves lacking a petiole are called epetiolate; the petiole is a stalk. In petiolate leaves, the leaf stalk may be long, as in the leaves of celery and rhubarb, short or absent, in which case the blade attaches directly to the stem and is said to be sessile. Subpetiolate leaves are nearly petiolate, or have an short petiole, may appear sessile; the broomrape family Orobanchaceae is an example of a family. In some other plant groups, such as the speedwell genus Veronica and sessile leaves may occur in different species. In the grasses the leaves are apetiolate, but the leaf blade may be narrowed at the junction with the leaf sheath to form a pseudopetiole, as in Pseudosasa japonica. In plants with compound leaves, the leaflets are attached to a continuation of the petiole called the rachis; each leaflet may be attached to the rachis by a short stalk called the petiolule.
There may be swollen regions at either end of the petiole known as pulvina that are composed of a flexible tissue that allows leaf movement. Pulvina are common in the prayer plant family Marantaceae. A pulvinus on a petiolule is called a pulvinulus. In some plants, the petioles are flattened and widened, to become phyllodes or phyllodia, or cladophylls and the true leaves may be reduced or absent. Thus, the phyllode comes to serve the functions of the leaf. Phyllodes are common in the genus Acacia the Australian species, at one time put in Acacia subgenus Phyllodineae. In Acacia koa, the phyllodes are leathery and thick, allowing the tree to survive stressful environments; the petiole allows submerged hydrophytes to have leaves floating at different depths, the petiole being between the node and the stem. In plants such as rhubarb, celery and cardoons the petioles are cultivated as edible crops; the petiole of rhubarb produces the leaf at its end. Botanically it is culinarily used as a fruit. Petiole comes from Latin petiolus, or peciolus "little foot", "stem", an alternative diminutive of pes "foot".
The regular diminutive pediculus is used for "foot stalk". Hyponastic response Pedicel "Petiole". Collier's New Encyclopedia. 1921
United States Department of Agriculture
The United States Department of Agriculture known as the Agriculture Department, is the U. S. federal executive department responsible for developing and executing federal laws related to farming and food. It aims to meet the needs of farmers and ranchers, promote agricultural trade and production, work to assure food safety, protect natural resources, foster rural communities and end hunger in the United States and internationally. 80% of the USDA's $141 billion budget goes to the Food and Nutrition Service program. The largest component of the FNS budget is the Supplemental Nutrition Assistance Program, the cornerstone of USDA's nutrition assistance; the current Secretary of Agriculture is Sonny Perdue. Many of the programs concerned with the distribution of food and nutrition to people of America and providing nourishment as well as nutrition education to those in need are run and operated under the USDA Food and Nutrition Service. Activities in this program include the Supplemental Nutrition Assistance Program, which provides healthy food to over 40 million low-income and homeless people each month.
USDA is a member of the United States Interagency Council on Homelessness, where it is committed to working with other agencies to ensure these mainstream benefits are accessed by those experiencing homelessness. The USDA is concerned with assisting farmers and food producers with the sale of crops and food on both the domestic and world markets, it plays a role in overseas aid programs by providing surplus foods to developing countries. This aid can go through USAID, foreign governments, international bodies such as World Food Program, or approved nonprofits; the Agricultural Act of 1949, section 416 and Agricultural Trade Development and Assistance Act of 1954 known as Food for Peace, provides the legal basis of such actions. The USDA is a partner of the World Cocoa Foundation. Early in its history, the economy of the United States was agrarian. Officials in the federal government had long sought new and improved varieties of seeds and animals for import into the United States. In 1837 Henry Leavitt Ellsworth, a Yale-educated attorney interested in improving agriculture, became Commissioner of Patents, a position within the Department of State.
He began collecting and distributing new varieties of seeds and plants through members of the Congress and agricultural societies. In 1839, Congress established the Agricultural Division within the Patent Office and allotted $1,000 for "the collection of agricultural statistics and other agricultural purposes." Ellsworth's interest in aiding agriculture was evident in his annual reports that called for a public depository to preserve and distribute the new seeds and plants, a clerk to collect agricultural statistics, statewide reports about crops in different regions, the application of chemistry to agriculture. Ellsworth was called the "Father of the Department of Agriculture."In 1849, the Patent Office was transferred to the newly created Department of the Interior. In the ensuing years, agitation for a separate bureau of agriculture within the department or a separate department devoted to agriculture kept recurring. On May 15, 1862, Abraham Lincoln established the independent Department of Agriculture to be headed by a commissioner without Cabinet status, the agriculturalist Isaac Newton was appointed to be the first such commissioner.
Lincoln called it the "people's department." In 1868, the Department moved into the new Department of Agriculture Building in Washington, D. C. designed by famed DC architect Adolf Cluss. Located on Reservation No.2 on the National Mall between 12th Street and 14th SW, the Department had offices for its staff and the entire width of the Mall up to B Street NW to plant and experiment with plants. In the 1880s, varied advocacy groups were lobbying for Cabinet representation. Business interests sought a Department of Commerce and Industry, farmers tried to raise the Department of Agriculture to Cabinet rank. In 1887, the House of Representatives and Senate passed bills giving Cabinet status to the Department of Agriculture and Labor, but the bill was defeated in conference committee after farm interests objected to the addition of labor. On February 9, 1889, President Grover Cleveland signed a bill into law elevating the Department of Agriculture to Cabinet level. In 1887, the Hatch Act provided for the federal funding of agricultural experiment stations in each state.
The Smith-Lever Act of 1914 funded cooperative extension services in each state to teach agriculture, home economics, other subjects to the public. With these and similar provisions, the USDA reached out to every county of every state. During the Great Depression, farming remained a common way of life for millions of Americans; the Department of Agriculture's Bureau of Home Economics, established in 1923, published shopping advice and recipes to stretch family budgets and make food go farther. USDA helped ensure that food continued to be produced and distributed to those who needed it, assisted with loans for small landowners, contributed to the education of the rural youth, it was revealed on August 27th, 2018 that the U. S. Department of Agriculture would be providing U. S. farmers with a farm aid package, which will total $4.7 billion in direct payments to American farmers. This package is meant to offset the losses farmers are expected to incur from retaliatory tariffs placed on American exports during the Trump tariffs.
The Department of Agriculture was authorized a budget for Fiscal Year 2015 of $139.7 billion. The budget authorization is broken down as follows: Agricultural Stabilization and Conservation Service Animal Damage Control (
