Crinum is a genus of about 180 species of perennial plants that have large showy flowers on leafless stems, and develop from bulbs. They are found in seasonally moist areas, including marshes, swamps, depressions and along the sides of streams and lakes in tropical and subtropical areas worldwide.
Crinum are bulbous perennial herbs [3] [4] with tunicate bulbs [5] and basal, glabrous, [6] annual to perennial leaves. [3]
The bisexual, [5] [3] sessile or pedicellate, [5] [4] zygomorphic or actinomorphic flowers [4] are borne one umbellate or solitary inflorescences [3] [4] with solid scapes. [4]
Cytological studies have shown that 27 species of Crinum are diploid, having a typical chromosome count of 2n = 22. Abilio Fernandes found that the Orange River Crinum bulbispermum had a count of 2n = 66, and some desert Crinum macowanii 2n = 44. These polyploid species produce seeds that are often parthenogenetic triploid or diploids, lack vigour and seldom grow to mature plants. [7]
It was published by Carl Linnaeus in 1753. [8] [2] The lectotype Crinum americanum L. was designated in 1923. [2]
As of July 2014 [update] , the World Checklist of Selected Plant Families lists 105 species of Crinum. [9] Amongst these are:
The generic name Crinum comes from the Ancient Greek κρίνον (krinon), meaning lily, via the Latin crinum. [13]
Several species are used in aquariums and in aquascaping. These include Crinum calamistratum , Crinum malabaricum , Crinum natans , and Crinum thaianum . [14]
Amaryllis is the only genus in the subtribe Amaryllidinae. It is a small genus of flowering bulbs, with two species. The better known of the two, Amaryllis belladonna, is a native of the Western Cape region of South Africa, particularly the rocky southwest area between the Olifants River Valley and Knysna.
Erythronium, the fawn lily, trout lily, dog's-tooth violet or adder's tongue, is a genus of Eurasian and North American plants in the lily family, most closely related to tulips. The name Erythronium derives from Ancient Greek ἐρυθρός (eruthrós) "red" in Greek, referring to the red flowers of E. dens-canis. Of all the established species, most live in North America; only six species are found in Europe and Asia.
Theobroma is a genus of flowering plants in the mallow family, Malvaceae. It was previously classified as a member of Sterculiaceae, which has been incorporated into Malvaceae to make it monophyletic. It contains roughly 20 species of small understory trees native to the tropical forests of Central and South America.
Nuphar lutea, the yellow water-lily, brandy-bottle, or spadderdock, is an aquatic plant of the family Nymphaeaceae, native to northern temperate and some subtropical regions of Europe, northwest Africa, and western Asia. This species was used as a food source and in medicinal practices from prehistoric times with potential research and medical applications going forward.
Crinum pedunculatum also known as the swamp lily, river lily or mangrove lily, is a bulbous perennial found in stream and tidal areas of the Northern Territory, Queensland and New South Wales, Australia as well as New Guinea and some Pacific Islands. It is unclear whether it is native or introduced to Norfolk Island.
Crinum bulbispermum is a herbaceous plant native to South Africa, Lesotho and Eswatini. It is naturalized in the Lesser Antilles, Honduras, Cuba, Florida, Texas, Louisiana, Alabama, South Carolina and North Carolina. Crinum bulbispermum is the floral emblem of the Free State province of South Africa.
Crinum thaianum, also called the Thai onion plant or water onion, is an emergent plant species, endemic to the coastal plain of Ranong and Phang Nga Provinces, Thailand. Its natural habitat is to grow along the banks of flowing, medium- to fast-running streams, where its roots and bulb are submerged in the sediment, while its leaves grow long in the current and can access fresh air at the surface. When in bloom, the flower is an umbel of large, showy blossoms above the waterline. These growth habits make it a wonderful addition for tropical aquaria, and it is sold in many regions to be used specifically for growth within displays of tropical fish. It also serves the added benefit of oxygenating the water and absorbing ammonia, which is toxic to most aquatic animals. In nature, however, the species is threatened with extinction, and diminishing rapidly, due to habitat destruction.
Tulipa gesneriana, the Didier's tulip or garden tulip, is a species of plant in the lily family, cultivated as an ornamental in many countries because of its large, showy flowers. This tall, late-blooming species has a single blooming flower and linear or broadly lanceolate leaves. This is a complex hybridized neo-species, and can also be called Tulipa × gesneriana. Most of the cultivars of tulip are derived from Tulipa gesneriana. It has become naturalised in parts of central and southern Europe and scattered locations in North America.
Crinum asiaticum, commonly known as poison bulb, giant crinum lily, grand crinum lily, or spider lily, is a plant species widely planted in many warmer regions as an ornamental. It is a bulb-forming perennial producing an umbel of large, showy flowers that are prized by gardeners. However, all parts of the plant are poisonous if ingested. Some reports indicate exposure to the sap may cause skin irritation.
Ammocharis is a small genus from sub-Saharan Africa, in the family Amaryllidaceae which includes seven species distributed in Africa. The plant grows as above-ground bulb, preferring seasonally wet, hot, sandy soils and full sun.
Abroma augustum, sometimes written Abroma augusta, Devil's cotton, is a species of Abroma. It has dark red flowers with a characteristic and unusual appearance. It is widely distributed in Asia. It was previously thought to grow in north Queensland but the most recent survey did not find it.
Lycoris radiata, known as the red spider lily, red magic lily, corpse flower, or equinox flower, is a plant in the amaryllis family, Amaryllidaceae, subfamily Amaryllidoideae. It is originally from China, Japan, Korea and Nepal and spread from there to the United States and elsewhere. It is considered naturalized in Seychelles and in the Ryukyu Islands. It flowers in the late summer or autumn, often in response to heavy rainfall. The common name hurricane lily refers to this characteristic, as do other common names, such as resurrection lily; these may be used for the genus as a whole.
Nerine bowdenii is a species of flowering plant in the family Amaryllidaceae. It is an herbaceous bulbous perennial, growing to 45 cm (18 in) tall by 8 cm (3 in), with strap-shaped leaves and large umbels of lily-like pink flowers in late summer and autumn. The common names of the species are Cornish lily, Cape flower, Guernsey lily, and Bowden lily. However, it is neither a true lily nor from Cornwall or Guernsey, but originates from South Africa. Confusingly the name “Guernsey lily” is also applied to a related species, Nerine sarniensis.
Spodoptera picta, the lily caterpillar, is a moth of the family Noctuidae. It was described by Félix Édouard Guérin-Méneville in 1838. It is found from India, South-east Asia and Japan through Indonesia and the western part of South Pacific ocean to Fiji.
Crinum flaccidum, known variously as the Darling lily, Murray lily or Macquarie lily, is a species of flowering plant in the family Amaryllidaceae. It is native to inland Australia. The Darling river people — the Paakantyi — called this plant paalampaltharu.
Cyrtanthus obliquus, the Knysna lily, is a species of flowering plant in the amaryllis family. It has spiralling leaves and large pendulous flowers. It is native to coastal grasslands from KwaZulu-Natal to the Eastern Cape, South Africa.
Crinum macowanii is a species of flowering plant in the Amaryllidaceae family. It is a deciduous bulbous plant species native to Africa that has been used in traditional medicine throughout southern Africa.
