Species

About 180 species, see text.

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.

Description

Crinum leaves are basal, typically long and strap-shaped, with colors ranging from light green to green.

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. [2]

Taxonomy

As of July 2014, the World Checklist of Selected Plant Families lists 105 species of Crinum. [3] Amongst these are:

Hybrids

Uses

Several species are used in aquariums and in aquascaping. These include Crinum calamistratum , Crinum malabaricum , Crinum natans , and Crinum thaianum . [7]

<i>Amaryllis</i> Genus of plants

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.

<i>Erythronium</i> Genus of flowering plants

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.

<i>Hippeastrum</i> Genus of flowering plants in the family Amaryllidaceae

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.

<i>Anthericum</i> Genus of flowering plants belonging to the agave, yucca, and Joshua tree subfamily

Anthericum is a genus of about 65 species, rhizomatous perennial plants in the family Asparagaceae, subfamily Agavoideae. It was formerly placed in its own family, Anthericaceae. The species have rhizomatous or tuberous roots, long narrow leaves and branched stems carrying starry white flowers. The members of this genus occur mainly in the tropics and southern Africa and Madagascar, but are also represented in Europe.

<i>Amaryllis belladonna</i> Species of flowering plant in the family Amaryllidaceae

Amaryllis belladonna, the Jersey lily, belladonna-lily, naked-lady-lily, or March lily, is a plant species native to Cape Province in South Africa but widely cultivated as an ornamental. It is reportedly naturalized in many places: Corsica, Portugal, the Azores, Madeira, the Canary Islands, the Scilly Isles of Great Britain, the Democratic Republic of the Congo, Ascension Island, Australia, New Zealand, Mexico, Cuba, Haiti, the Dominican Republic, Chile, California, Texas, Louisiana, Mississippi, Michigan and the Juan Fernández Islands.

<i>Crinum pedunculatum</i> Species of flowering plant

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.

<i>Crinum bulbispermum</i> Species of flowering plants in the family Amaryllidaceae

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.

<i>Crinum thaianum</i> Species of aquatic plant

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.

<i>Crinum asiaticum</i> Species of flowering plant in the family Amaryllidaceae

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.

<i>Ammocharis</i> Genus of flowering plants

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.

<i>Cyrtanthus</i> Genus of flowering plants

Cyrtanthus is a genus of perennial, herbaceous and bulbous plants in the family Amaryllidaceae, subfamily Amaryllidoideae.

<i>× Amarcrinum</i> Genus of flowering plants

The scientific name × Amarcrinum is applied to those hybrid plants obtained from artificial crosses between the genera Amaryllis and Crinum, although as of March 2014, the World Checklist of Selected Plant Families regards the name as "unplaced". They are grown as ornamental plants in gardens.

<i>Nerine bowdenii</i> Species of flowering plant

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.

<i>Spodoptera picta</i> Species of moth

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 in from India, South-east Asia and Japan through Indonesia and the western part of South Pacific ocean to Fiji.

<i>Cyrtanthus obliquus</i> Species of flowering plant

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.

<i>Cyrtanthus falcatus</i> Species of flowering plant

Cyrtanthus falcatus, the falcate fire lily, is a species of flowering plant in the amaryllis family Amaryllidaceae from the Natal region of South Africa. A bulbous perennial growing to 30 cm (12 in), it has glossy, strap-shaped leaves and erect burgundy-coloured stems. These bear umbels of 8-10 narrowly-flared, pendulous tubular flowers in shades of red, green and cream in spring and summer. The umbels are bent over in a curious crook or sickle shape. The plant goes dormant in winter. The bulb, shaped like a bowling pin, rests with its neck above the soil line.
