Dear Jim, No there is not a single word about Iris susiana in those papers. From what I know Iris susiana has been for long in cultivation in Turkey. According to Mathew it bears a great resemblace to iris sofarana and Iris basaltica and may be a form of one of these. They seem to be some more information in the following paper : Avishai?M. &?Zohary D. 1980. Genetic affinities among the Oncocyclus irises. Botanical Gazette, Vol. 141, No. 1, pp. 107-115 but I have not purchased that paper yet. I will carry on searching for more info and let you know. Luc
