Quinoa is a flowering plant in the amaranth family. It is a herbaceous annual plant grown as a crop primarily for its edible seeds; the seeds are rich in protein, dietary fiber, B vitamins and dietary minerals in amounts greater than in many grains. Quinoa is not a grass but rather a pseudocereal botanically related to spinach and amaranth, and originated in the Andean region of northwestern South America. It was first used to feed livestock 5,200–7,000 years ago, and for human consumption 3,000–4,000 years ago in the Lake Titicaca basin of Peru and Bolivia.
Chili peppers, also spelled chile or chilli, are varieties of berry-fruit plants from the genus Capsicum, which are members of the nightshade family Solanaceae, cultivated for their pungency. Chili peppers are widely used in many cuisines as a spice to add "heat" to dishes. Capsaicin and the related capsaicinoids give chili peppers their intensity when ingested or applied topically. Chili peppers exhibit a range of heat and flavors. This diversity is the reason behind the availability of different types of chili powder, each offering its own taste and heat level.
Ullucus is a genus of flowering plants in the family Basellaceae, with one species, Ullucus tuberosus, a plant grown primarily as a root vegetable, secondarily as a leaf vegetable. The name ulluco is derived from the Quechua word ulluku, but depending on the region, it has many different names. These include illaco, melloco, chungua or ruba, olluco or papalisa, or ulluma.
Capsicum pubescens is a plant of the genus Capsicum (pepper). The species name, pubescens, refers to the hairy leaves of this pepper. The hairiness of the leaves, along with the black seeds, make Capsicum pubescens distinguishable from other Capsicum species. Capsicum pubescens has pungent yellow, orange, red, green or brown fruits.
Capsicum annuum, commonly known as paprika, chili pepper, red pepper, sweet pepper, jalapeño, cayenne, or bell pepper, is a fruiting plant from the family Solanaceae (nightshades), within the genus Capsicum which is native to the northern regions of South America and to southwestern North America. The plant produces berries of many colors including red, green, and yellow, often with pungent taste. It is also one of the oldest cultivated crops, with domestication dating back to around 6,000 years ago in regions of Mexico. The genus Capsicum has over 30 species but Capsicum annuum is the primary species in its genus, as it has been widely cultivated for human consumption for a substantial amount of time and has spread across the world. This species has many uses in culinary applications, medicine, self defense, and can even be ornamental.
Chenopodium pallidicaule, known as cañihua, canihua or cañahua and also kañiwa or kaniwa, is a species of goosefoot, similar in character and uses to the closely related quinoa.
Capsicum frutescens is a wild chili pepper having genetic proximity to the cultivated pepper Capsicum chinense native to Central and South America. Pepper cultivars of C. frutescens can be annual or short-lived perennial plants. Flowers are white with a greenish white or greenish yellow corolla, and are either insect- or self-pollinated. The plants' berries typically grow erect; ellipsoid-conical to lanceoloid shaped. They are usually very small and pungent, growing 10–20 millimetres (0.39–0.79 in) long and 3–7 millimetres (0.12–0.28 in) in diameter. Fruit typically grows a pale yellow and matures to a bright red, but can also be other colors. C. frutescens has a smaller variety of shapes compared to other Capsicum species. C. frutescens has been bred to produce ornamental strains because of its large quantities of erect peppers growing in colorful ripening patterns.
Capsicum chinense, commonly known as a "habanero-type pepper", is a species of chili pepper native to the Americas. C. chinense varieties are well known for their unique flavors and, in many cases, exceptional heat. The hottest peppers in the world are members of this species, with a Scoville Heat Unit score of 2.69 million measured in the C. chinense cultivar Pepper X in 2023.
Domesticated plants of Mesoamerica, established by agricultural developments and practices over several thousand years of pre-Columbian history, include maize and capsicum. A list of Mesoamerican cultivars and staples:
During 10,000 years of cultivation, numerous forms of wheat, many of them hybrids, have developed under a combination of artificial and natural selection. This diversity has led to much confusion in the naming of wheats. Genetic and morphological characteristics of wheat influence its classification; many common and botanical names of wheat are in current use.
The Eastern Agricultural Complex in the woodlands of eastern North America was one of about 10 independent centers of plant domestication in the pre-historic world. Incipient agriculture dates back to about 5300 BCE. By about 1800 BCE the Native Americans of the woodlands were cultivating several species of food plants, thus beginning a transition from a hunter-gatherer economy to agriculture. After 200 BCE when maize from Mexico was introduced to the Eastern Woodlands, the Native Americans of the eastern United States and adjacent Canada slowly changed from growing local indigenous plants to a maize-based agricultural economy. The cultivation of local indigenous plants other than squash and sunflower declined and was eventually abandoned. The formerly domesticated plants returned to their wild forms.
Capsicum baccatum is a member of the genus Capsicum, and is one of the five domesticated chili pepper species. The fruit tends to be very pungent, and registers 30,000 to 50,000 on the Scoville heat unit scale.
The following outline is an overview of and topical guide to botany, the biological academic discipline involving the study of plants.
Pamela Soltis is an American botanist. She is a distinguished professor at the University of Florida, curator at the Florida Museum of Natural History, principal investigator of the Laboratory of Molecular Systematics and Evolutionary Genetics at the Florida Museum of Natural History, and founding director of the University of Florida Biodiversity Institute.
Capsicum is a genus of flowering plants in the nightshade family Solanaceae, native to the Americas, cultivated worldwide for their edible fruit, which are generally known as "peppers" or "capsicum". Chili peppers grow on five species of Capsicum. Sweet or bell peppers and some chili peppers are Capsicum annuum, making it the most cultivated species in the genus.
Capsicum cardenasii is a plant species in the genus Capsicum and the family Solanaceae. It is a diploid with 2n=2x=24. It is a member within the C. pubescens complex, a group of closely related Capsicum species. It is closely related to C. eximium. It is native to the Andes, and it can be found in Bolivia and Peru. The native name is ulupica.
Capsicum eximium is a member of the genus Capsicum with 2n=2x=24, and native to the New World, specifically the Andean region of South America. It is one of the "purple-flowered" Capsicums along with Capsicum cardenasii and Capsicum pubescens. Like most other chili peppers, it is both pungent and self-compatible. It is a member of the Pubescenscomplex, a natural group of highly related Capsicums. Natural hybrids between C. pubescens as well as C. tovarii have been found, further supporting the relationship of these species.
Barbara Lynette Rye is an Australian botanist born in 1952.
Charles Bixler Heiser Jr. (1920–2010) was a professor of botany, known as a leading expert on the sunflower genus Helianthus. He is also noteworthy as the author of a "series of popular books that did much to promote botany to the general public."
