Kalmia latifolia, the mountain laurel, calico-bush, or spoonwood, is a species of flowering plant in the heath family Ericaceae, that is native to the eastern United States. Its range stretches from southern Maine south to northern Florida, and west to Indiana and Louisiana. Mountain laurel is the state flower of Connecticut and Pennsylvania. It is the namesake of Laurel County in Kentucky, the city of Laurel, Mississippi, and the Laurel Highlands in southwestern Pennsylvania.
Rice is a cereal grain, and in its domesticated form is the staple food for over half of the world's human population, particularly in Asia and Africa, due to the vast amount of soil that is able to grow rice. Rice is the seed of the grass species Oryza sativa or, much less commonly, O. glaberrima. Asian rice was domesticated in China some 13,500 to 8,200 years ago, while African rice was domesticated in Africa some 3,000 years ago. Rice has become commonplace in many cultures worldwide; in 2021, 787 million tons were produced, placing it fourth after sugarcane, maize, and wheat. Only some 8% of rice is traded internationally. China, India, and Indonesia are the largest consumers of rice. A substantial amount of the rice produced in developing nations is lost after harvest through factors such as poor transport and storage. Rice yields can be reduced by pests including insects, rodents, and birds, as well as by weeds, and by diseases such as rice blast. Traditional polycultures such as rice-duck farming, and modern integrated pest management seek to control damage from pests in a sustainable way.
Oryza is a genus of plants in the grass family. It includes the major food crop rice. Members of the genus grow as tall, wetland grasses, growing to 1–2 metres (3–7 ft) tall; the genus includes both annual and perennial species.
Oryza sativa, also known as rice, is the plant species most commonly referred to in English as rice. It is the type of farmed rice whose cultivars are most common globally, and was first domesticated in the Yangtze River basin in China 13,500 to 8,200 years ago.
Typha latifolia, better known as broadleaf cattail, is a perennial herbaceous plant in the genus Typha. It is found as a native plant species in North and South America, Eurasia, and Africa. The T. latifolia genome was published in 2022.
Sagittaria latifolia is a plant found in shallow wetlands and is sometimes known as broadleaf arrowhead, duck-potato, Indian potato, or wapato. This plant produces edible tubers that have traditionally been extensively used by Native Americans.
Fraxinus latifolia, the Oregon ash, is a member of the ash genus Fraxinus, native to western North America.
Lysimachia borealis, the starflower, is a North American woodland perennial that blooms between May and June.
Typha angustifolia L. is a perennial herbaceous plant of genus Typha. This cattail is an "obligate wetland" species that is commonly found in the northern hemisphere in fresh water or brackish locations.
Oryza barthii, also called Barth's rice, wild rice, or African wild rice, is a grass in the rice genus Oryza. It is an annual, erect to semierect grass. It has leaves with a short ligule, and panicles that are compact to open, rarely having secondary branching. The inflorescence structure are large spikelets, 7.7–12.3 millimetres long and 2.3–3.5 millimetres wide, with strong awns, usually red. The inflorescences have anthers 1.5–3 millimetres long.
Oryza rufipogon, known as brownbeard rice, wild rice, and red rice, is a member of the genus Oryza.
Oryza longistaminata is a perennial species of grass from the same genus as cultivated rice. It is native to most of sub-Saharan Africa and Madagascar. It has been introduced into the United States, where it is often regarded as a noxious weed. Its common names are longstamen rice and red rice.
Arnica latifolia is a species of arnica in the sunflower family, known by the common names broadleaf arnica, broad leaved arnica, mountain arnica, and daffodil leopardbane. It is native to western North America from Alaska east to Northwest Territories and south to Mono County, California, and Taos County, New Mexico. It grows in mountain habitat such as forest and meadows.
Oryza nivara is a wild progenitor of the cultivated rice Oryza sativa. It is found growing in swampy areas, at edge of pond and tanks, beside streams, in ditches, in or around rice fields. Grows in shallow water up to 0.3 metres, in seasonally dry and open habitats.
Porteresia coarctata is a species of grass in the family Poaceae, native to India, Sri Lanka, Bangladesh, and Myanmar.
Lavandula latifolia, known as broadleaved lavender, spike lavender, aspic lavender or Portuguese lavender, is a flowering plant in the family Lamiaceae, native to the western Mediterranean region, from central Portugal to northern Italy (Liguria) through Spain and southern France. Hybridization can occur in the wild with English lavender.
Oryza brachyantha is a grass in the rice genus Oryza, distantly related to cultivated rice O. sativa, and native to tropical Africa. It is an annual grass that grows as a tuft.
Oryza punctata is an annual grass in the rice genus Oryza, also known as red rice, related to cultivated rice O. sativa. O. punctata forms clumps or tussocks from 50–120 cm tall. It is a native to tropical Africa and Madagascar but is also found in Thailand and other parts of Indochina. O. punctata is a weed species in commercial rice growing operations although it appears to be rare in its native range. O. punctata has an IUCN status of least concern. It is not generally eaten or used as fodder by farmers but there is some evidence that it has been used as such during periods of famine. Due to the importance of the crop varieties of rice globally, the evolution of the Oryza genus as a whole has been studied extensively. A lot of information about O. punctata has been elucidated as a secondary benefit to this commercial research. O. punctata evolved some 5 million years ago in the second of two rapid radiation events that occurred in the Oryza L. genus.
Zizania latifolia, known as Manchurian wild rice, is the only member of the wild rice genus Zizania native to Asia. It is used as a food plant. Both the stem and grain are edible. Gathered in the wild, Manchurian wild rice was an important grain in ancient China. A wetland plant, Manchurian wild rice is now very rare in the wild, and its use as a grain has completely disappeared in Asia, though it continues to be cultivated for its stems. A measure of its former popularity is that the surname Jiǎng, one of the most common in China, derives from this crop.
Amazon wild rice refers to either of the two native (endemic) species of rice (Oryza) found in the Amazon region of South America and adjacent tropical areas, Oryza glumaepatula and Oryza latifolia. It also can refer to the cultivated form Oryza sp. which was domesticated from one or both of the wild forms some 4,000 years ago by the indigenous people of the Amazon region. South America actually has 4 indigenous wild rice species, Oryza alta, Oryza latifolia, Oryza grandiglumis, and Oryza glumaepatula, all of which can be found in the Amazon basin of Brazil and could therefore be considered Amazonian wild rice.
