An onion, also known as the bulb onion or common onion, is a vegetable that is the most widely cultivated species of the genus Allium. The shallot is a botanical variety of the onion which was classified as a separate species until 2011. Its close relatives include garlic, scallion, leek, and chive.
In botany, a bulb is structurally a short stem with fleshy leaves or leaf bases that function as food storage organs during dormancy.
Lilium is a genus of herbaceous flowering plants growing from bulbs, all with large prominent flowers. They are the true lilies. Lilies are a group of flowering plants which are important in culture and literature in much of the world. Most species are native to the Northern Hemisphere and their range is temperate climates and extends into the subtropics. Many other plants have "lily" in their common names, but do not belong to the same genus and are therefore not true lilies.
Narcissus is a genus of predominantly spring flowering perennial plants of the amaryllis family, Amaryllidaceae. Various common names including daffodil, narcissus and jonquil, are used to describe all or some members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by a cup- or trumpet-shaped corona. The flowers are generally white and yellow, with either uniform or contrasting coloured tepals and corona.
Hippeastrum is a genus of about 90 species and over 600 hybrids and cultivars of perennial herbaceous bulbous plants. They generally have large fleshy bulbs and tall broad leaves, generally evergreen, and large red or purple flowers.
Caladium is a genus of flowering plants in the family Araceae. They are often known by the common name elephant ear, heart of Jesus, and angel wings. There are over 1000 named cultivars of Caladium bicolor from the original South American plant.
Eucrosia aurantiaca is a species of plant which is endemic to Ecuador. Its natural habitats are subtropical or tropical dry forests and subtropical or tropical dry shrubland. It is threatened by habitat loss.
Eucrosia is a genus of herbaceous, perennial and bulbous plants in the Amaryllis family distributed from Ecuador to Peru. The name is derived from the Greek eu, beautiful, and krossos, a fringe, referring to the long stamens. As circumscribed in 2020, the genus contains six species. Phaedranassa and Rauhia are the genera most closely related to Eucrosia.
Urceolina dodsonii, formerly known as Eucrosia dodsonii, is a species of plant that is endemic to Ecuador. Its natural habitat is subtropical or tropical moist montane forests. It is threatened by habitat loss.
Eucrosia stricklandii is a species of plant which is endemic to Ecuador. Its natural habitats are subtropical or tropical dry forests and subtropical or tropical dry shrubland. It is threatened by habitat loss.
Phaedranassa is a genus of South American and Central American plants in Amaryllis family, subfamily Amaryllidoideae.
Ismene, or Peruvian daffodil, is a genus of South American plants in the Amaryllis family. The species are native to Peru and Ecuador and widely cultivated elsewhere as ornamentals because of their large, showy flowers.
Tulips (Tulipa) are a genus of spring-blooming perennial herbaceous bulbiferous geophytes. The flowers are usually large, showy, and brightly coloured, generally red, orange, pink, yellow, or white. They often have a different coloured blotch at the base of the tepals, internally. Because of a degree of variability within the populations and a long history of cultivation, classification has been complex and controversial. The tulip is a member of the lily family, Liliaceae, along with 14 other genera, where it is most closely related to Amana, Erythronium, and Gagea in the tribe Lilieae.
Eucrosia bicolor is a species of plant found in Ecuador and Peru. Its natural habitats are seasonally dry lowland areas. It was the first species of Eucrosia to be scientifically described, in 1817, and the first to be introduced into cultivation in Europe, flowering outside its homeland for the first time in 1817. It is the most widely grown species of Eucrosia.
Eucrosia eucrosioides is a species of plant that is found in south west Ecuador and north Peru. Its natural habitats are seasonally dry lowland areas.
Eucrosia mirabilis is a species of plant from Ecuador. In the original scientific description in 1869, it was believed to be from Peru, but there is little evidence it ever grew there. The plant disappeared from cultivation until it was found in Ecuador in 1997. Its natural habitats are seasonally dry lowland areas to elevations of 1500 m.
Stenomesson tubiflorum is a species of plant which is endemic to Peru.
Oziroe is a genus of bulbous South American plants in the squill subfamily within the asparagus family. Within the Scilloideae, it is the sole member of the tribe Oziroëeae and the only genus in the subfamily to be found in the New World.
Urceolina is a genus of South American plants in the amaryllis family native to Bolivia, Brazil, Colombia, Costa Rica, Ecuador, Guatemala, Panama, and Peru. It has also been introduced to many South and Central American states, as well as India and Sri Lanka. The formerly accepted genera Eucharis and Caliphruria are now regarded as synonyms of this genus. Many species of this genus share the common name Amazon lily.
The two palpal bulbs – also known as palpal organs and genital bulbs – are the copulatory organs of a male spider. They are borne on the last segment of the pedipalps, giving the spider an appearance often described as like wearing boxing gloves. The palpal bulb does not actually produce sperm, being used only to transfer it to the female. Palpal bulbs are only fully developed in adult male spiders and are not completely visible until after the final moult. In the majority of species of spider, the bulbs have complex shapes and are important in identification.
