The RHS Advisory Committee on Nomenclature and agreed to adopt for the 2011–2012 edition of the RHS Finder the generic circumscriptions found in Goldblatt & Manning (2008). Two previously recognised monotypic genera, Belamcanda and Pardanthopsis, have now been sunk into Iris. Pardanthopsis dichotoma had previously been known as I. dichotoma, so no recombination was needed. On the other hand, as the epithet “chinensis” was already in use under Iris for a different species, Belamcanda chinensis needed the new name of I. domestica (L.) Goldblatt & Mabb. (Goldblatt & Mabberley, 2005).

However, there is also a between these two species, which is widely grown in horticulture under the common name candy lily. It was raised by Samuel Norris in 1967 by pollinating flowers of Iris dichotoma with pollen from I. domestica Avalon Hybrids. It was described by Lee Lenz some five years later as the bigeneric hybrid × Pardancanda norrisii. As this hybrid binomial does not appear to have a valid name under Iris, the requisite combination is published here.
