Plagiolirion is a monotypic genus in the family Amaryllidaceae endemic to Colombia.[2] It has only one known species, Plagiolirion horsmannii,[2] which is rare in the wild and was thought to be extinct until it was rediscovered in the Río Cauca Valley in 1989.[3]

Cytology
[edit | edit source]The diploid chromosome number of Plagiolirion horsmannii is 2n = 46.[3][10]

Etymology
[edit | edit source]The generic name Plagiolirion, from plagios meaning 'oblique' and leirion meaning 'lily',[7] is derived from the floral morphology.[6] The specific epithet horsmannii honours Fred Horsman,[8] who imported the species to Colchester, United Kingdom.[9][6][7]
