An excerpt from "SIGNA checklist":

KASHMIR WHITE (I. kashmiriana Baker X TB) 2n=50.
Foster was uncertain of the parentage of the cross producing Kashmir White
and Miss Wilmott. Although he believed that Iris kashmiriana was a parent,
Geddes Douglas in AIS Bulletin #87, p.. 40-44 presents another view. F.Denis
believed that Miss Wilmott came not from Iris kashmiriana but from a cross
of I. cypriana and I. pallida Dalmatica. He was able to synthesize his
hypothesis by crossing I. cypriana X I. pallida and getting a goodly
proportion of albinos. Since there is a yet no definitive proof either in
favor of Denis's belief or Foster's we have chosen arbitrarily to go with
Foster. These plants were at the base of most modern white TB lines...
