Belamcanda chinensis and Pardanthopsis dichotoma have been reclassified. Belamcanda chinensis is now called Iris domestica. Pardanthopsis dichotoma is now named Iris dichotoma. Goldblatt and Mabberley. Novon 15:128-132, 2005
I suppose Iris x norrisii is likely since there probably wasn't one with that species name already, although there HAVE been alot of iris species named.
