Range: Western Cascade Range from mid to southern Oregon; the southern Cascades, Klamath and Siskiyou mountains in northern California; 1000 to above 5000 feet elevation.
Original material: Grant's Pass, Josephine County, Oregon 1887
Key identifying features:
Flower color: White, cream to pale yellow, sometimes a yellow central eyespot; dark golden, reddish-brown or maroon-lavender veins.
Habitat: Road banks, meadows and similar exposed, sunny sites in pine or fir woodlands.
Name: By Thomas Jefferson Howell, Oregon's first pioneer botanist and collector of the original specimens, for the plant's yellowish-green leaves (chryso=golden + phyllo=leaf).
Comments: Long, slender style crests on delicate white to pale yellow or cream color flowers help distinguish I. chrysophylla from other similar wild iris, except its close relative Iris tenuissima. The relationship and distribution of these two in northern California calls out for further study. Unlike tenuissima, the floral tube in I. chrysophylla remains the same diameter from top to bottom - the top portion is not visibly dilated.
