Cytology
The diploid chromosome number of Plagiolirion horsmannii is 2n = 46.[3][10]
Taxonomy
The genus and species were first described by John Gilbert Baker in 1883.[4] The genus is placed in the tribe Eucharideae.[11]
Etymology
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]
