Iris foetidissima lutea is not a recognized variety. Iris foetidissima var. lutescens was, at one time recognized as a separate variety of Iris foetidissima, but it has since been determined to be not distinct enough to warrant varietal status.
Iris foetidissima var. citrina is a misnamed version of Iris citrina (which itself has been reclassified as a synonym of
Species Iris (Iris tenuissima) ) so that entry actually needs to be removed from the database.
To make a long story short
, the
Species Iris (Iris foetidissima) entry would be the proper place for your pictures.
