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[1][2] with tunicate bulbs[3] and basal, glabrous,[4] annual to perennial leaves.[1] These bulbs can be very large. A species which Chitendon and Synge list as Crinum crassipes (a synonym of Crinum variabile[5]) can have a bulb Template:Cvt high and Template:Cvt thick.,[6] exceeded only by Worsleya procera.

The bisexual,[3][1] sessile or pedicellate,[3][2] zygomorphic or actinomorphic flowers[2] are borne one umbellate or solitary inflorescences[1][2] with solid scapes.[2]

Cytology

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]

Taxonomy

It was published by Carl Linnaeus in 1753.[8][9] The lectotype Crinum americanum L.Script error: No such module "Check for unknown parameters". was designated in 1923.[9]

Hybrids

  • × Amarcrinum hybridised with Amaryllis
  • C. × powellii[12] (garden hybrid between C. bulbispermum and C. moorei) - pale pink, fragrant, lily-like flowers produced in late summer
    • C. × powellii 'Album'[13] (white flowered cultivar)

Etymology

The generic name Crinum comes from the Ancient Greek κρίνον (krinon), meaning lily, via the Latin crinum.[14]

Uses

Several species are used in aquariums and in aquascaping. These include Crinum calamistratum, Crinum malabaricum, Crinum natans, and Crinum thaianum.[15]
