Discussion | Iris macrosiphon hybridizes with I. chrysophylla, I. douglasiana, I. fernaldii, I. hartwegii, I. innominata, I. munzii, I. purdyi, I. tenax, and I. tenuissima. The invalid name “Iris californica” Leichtlin has sometimes been applied to a portion of this species. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
No natural hybrids of Iris munzii are known, but horticultural hybrids have been made with I. bracteata, I. douglasiana, I. hartwegii, I. innominata, and I. macrosiphon. It is known only from Tulare County, California. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
