Discussion | Plants with pedicels 2.8–4.7 cm, and flowers light purple or bluish violet have been recognized as subsp. australis. Plants having a 3-flowered inflorescence unit, leaves about 1 cm wide, and pale yellow flowers with golden yellow veining have been called subsp. columbiana. Plants having both flowers open at the same time rather than consecutively, pedicels averaging only 1 cm, long narrow style arms and crests, and floral tubes 1.2–1.5 cm have been named subsp. pinetorum. Iris hartwegii hybridizes with I. douglasiana, I. innominata, I. macrosiphon, I. munzii, I. tenax, and I. tenuissima. It is known from Butte County to Kern County.

Iris innominata hybridizes with I. bracteata, I. chrysophylla, I. douglasiana, I. fernaldii, I. macrosiphon, I. munzii, I. purdyi, and I. tenax. It is known only from southwestern Oregon and Del Norte County in northwestern California. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
