Derivation of the botanical name:
Gynandriris, Greek gyne, female and andros, male; refers to the united pistil and stamens.
sisyrinchium, Greek σίσύρα sisyra, 'a cloak of shaggy goat's skin' and was applied to this plant because of the thick covering of coarse fibres which surrounds the corm.
Moraea, in honor of (esquire of Shropshire) Robert More (1703-1780), an English amateur botanist and natural historian.
  • The standard author abbreviation L. is used to indicate Carl Linnaeus (1707 – 1778), a Swedish botanist, physician, and zoologist, the father of modern taxonomy.
  • The standard author abbreviation Parl. is used to indicate Filippo Parlatore (1816 – 1877), an Italian botanist.
The flowers are short-lived, opening around midday but closing again in the evening and not re-opening the following day.
