Rice is a flowering plant that produces small, inconspicuous flowers and seeds encased in a hull or husk. It is an annual plant, meaning it completes its life cycle within a single growing season, and it is adapted to grow in a wide range of environmental conditions, including flooded or waterlogged soils. In addition to being an important food crop, rice is also used for a variety of other purposes, including the production of biofuels, animal feed, and industrial products.
Species of rice and their botanical names.
There are two main species of rice that are cultivated worldwide: Oryza sativa and Oryza glaberrima.
Oryza sativa, also known as Asian rice or cultivated rice, is the most widely cultivated species of rice. It is native to tropical and subtropical regions of Asia and is grown in many countries around the world. There are thousands of varieties of Oryza sativa, which are divided into two main subspecies: Indica and Japonica.
Indica rice is adapted to hot, dry climates and is grown in many countries in South Asia, Southeast Asia, and the Middle East. It has long, slender grains and is typically used for long-grain rice dishes, such as basmati rice and jasmine rice.
Japonica rice is adapted to cool, moist climates and is grown in Japan, Korea, and parts of the United States. It has short, round grains and is typically used for short-grain rice dishes, such as sushi rice and Arborio rice.
Oryza glaberrima, also known as African rice or upland rice, is native to West Africa and is grown in several countries in that region. It is adapted to grow in upland or dryland conditions and is typically grown without irrigation. Oryza glaberrima is not as widely cultivated as Oryza sativa, but it is important in certain regions of West Africa where it is a staple food crop.
In addition to these two main species, there are also a number of other species of rice that are not widely cultivated, but which are important for research and breeding purposes. Some of these species include Oryza barthii, Oryza longistaminata, Oryza meridionalis, and Oryza punctata.
Asian rice - Oryza sativa
This is the most commonly grown species of rice.
Has two major subspecies: the sticky, short-grained japonica or sinica variety, and the nonsticky, long-grained indica rice variety.
Japonica rice varieties of are usually cultivated in dry fields, in temperate East Asia, upland areas of Southeast Asia, and high elevations in South Asia, while indica varieties are mainly lowland rices, grown mostly submerged, throughout tropical Asia.
This Rice occurs in a variety of colors, including white , brown , black, purple , and red rices. Black rice (also known as purple rice) is a range of rice types, some of which are glutinous rice.
An additional subspecies of O. sativa, which is broad-grained and thrives under tropical conditions, was identified based on morphology is known as tropical japonica.
African Rice - Oryza glaberrima
The botanical name of African rice is Oryza glaberrima. This species of rice is mostly grown in Africa.
It is hardy, pest-resistant, low-labour, suited to a variety of African conditions, filling, and has a distinct nutty flavour.
It is a tall rice plant, usually under 120 cm but up to five meters for floating varieties, which may also branch and root from higher stem nodes.
Generally, African rice has small, pear-shaped grain, reddish bran and green to black hulls , straight, simply-branched
panicles , and short, rounded ligules .
Oryza rufipogon
Oryza rufipogon is a species of rice that is native to Asia and is found in a number of countries in that region. It is a perennial grass that grows to a height of 1-2 meters and has long, narrow leaves and small, fragrant flowers.
Oryza rufipogon is not widely cultivated as a food crop, but it is an important plant in terms of plant breeding and genetics. It is one of the wild ancestor species of cultivated rice (Oryza sativa) and is considered a "gene pool" species because it contains a large number of genetic variations that can be used to improve the characteristics of cultivated rice.
Oryza rufipogon is also important for its ecological role as a natural vegetation in some parts of Asia. It is found in a variety of habitats, including wetlands, grasslands, and forests, and it is an important food source for a number of animals, including birds and small mammals.
In some parts of Asia, Oryza rufipogon is also used as a medicinal plant and is believed to have a number of therapeutic properties. It is used to treat a variety of ailments, including fever, inflammation, and respiratory problems.
Oryza australiensis
Oryza australiensis is a species of rice that is native to Australia. It is a perennial grass that grows to a height of 1-2 meters and has long, narrow leaves and small, fragrant flowers.
Oryza australiensis is not widely cultivated as a food crop, and it is not an important source of food for humans. However, it is an important plant in terms of plant breeding and genetics. It is one of the wild ancestor species of cultivated rice (Oryza sativa) and is considered a "gene pool" species because it contains a large number of genetic variations that can be used to improve the characteristics of cultivated rice.
Oryza barthii
Oryza barthii is a species of rice that is native to Africa. It is a perennial grass that grows to a height of 1-2 meters and has long, narrow leaves and small, fragrant flowers.
Oryza latifolia
Also known as broad-leaved rice or broadleaf rice, it is a wild rice grown in central and south America.
Oryza longistaminata
Oryza longistaminata is a species of rice that is native to South America. It is known for its long awns, which are slender, bristle-like appendages that grow from the lemma and palea (the outer and inner bracts, respectively) of the rice grain. The awns of O. longistaminata are longer than those of most other rice species, hence the species name "longistaminata." It is not a major crop, but it is grown in some parts of South America for its edible grains.

Botanical description of rice.
Rice is a grass species (Oryza sativa) that is widely cultivated as a staple food crop. It is the most important grain with regard to human nutrition and caloric intake, providing more than one fifth of the calories consumed worldwide by humans.
Rice plants are annuals that grow to a height of 1.2-1.8 meters, depending on the variety. They have long, narrow leaves that are bright green in color and grow in an upright, slender stalk. The flowers of the rice plant are small and fragrant, and they produce the grains of rice that are harvested.
Rice is typically grown in paddies, which are flooded fields that are used to irrigate the plants. This method of cultivation is called paddy rice cultivation, and it is the most common way to grow rice. There are also several other methods of cultivating rice, including dryland rice cultivation and upland rice cultivation.
Rice is a cereal grain and is a member of the grass family (Poaceae). It is native to tropical and subtropical regions of Asia and Africa, and it is grown in many countries around the world.
The rice plant is an annual grass and grows to about 120 centimetres (4 feet) in height. The leaves are long and flattened and are borne on hollow stems. It has a fibrous root system which is often broad and spreading.
The rice stem known as culm is hollow and is made up of nodes and internodes. Each node bears a leaf and bud, which may grow into a shoot or tiller. Primary tillers grow out of the main culm.
Rice grain is the ripened ovary with lemma and palea firmly adhered to it. The lemma and palea with other smaller components from the hull are removed in shelling rice for consumption.
The inflorescence is made up of spikelets bearing flowers that produce the fruit, or grain.
Varieties differ greatly in the length, shape, and weight of the panicle and the overall productivity of a given plant. This normally serves a great function in the botanical identifications.
Important uses of Rice.
Rice is a staple food for a large portion of the world's population, and it is used in a variety of dishes in many different cultures. It is a versatile grain that can be served as a side dish, used as a base for a main dish, or used to make a variety of baked goods and desserts.
In addition to its use as a food, rice has a number of other important uses. It is used as a source of fuel, either by burning the straw or the husks of the grain. Rice straw is also used as a building material in some parts of the world.
Rice husks, which are the hard outer shells of the rice grain, are used as a source of silicon carbide, which is a very hard material that is used in a number of industrial applications. Rice husks are also used as a feedstock for the production of cellulosic ethanol, which is a type of biofuel.
Rice bran, which is the outer layer of the rice grain, is rich in nutrients and is used as a feed for livestock. It is also used as a source of oil, which is extracted from the bran. Rice bran oil is used in cooking and as a base for cosmetics and other personal care products.
Rice is also used in the production of sake, a type of rice wine that is popular in Japan.
