Botanical Synonyms:



Pacific Coast Native, Californicae (D. Kramb, 05-OCT-03)

Common Names:

Yellow-leaf Iris (D. Kramb, 05-JAN-04)

Chromosome Count:

2n=40 according to the SIGNA Checklist of Iris Species (D. Kramb, 14-SEP-04)

General Description:

4"-10" (10-25cm), cream of very pale yellow with dark veining (D. Kramb, 05-OCT-03)

Creamy white to pale yellow, with dark golden or reddish-brown veins. Delicate white to pale yellow flowers with narrow parts and long, slender style crests show the close kinship of this iris with I. tenuissima in the long floral tube group of PCNIs. Unlike that species, I. chrysophylla lacks a distinctively dilated floral tube. (D. Kramb, 05-JAN-04)

Distinguishing Features:

Long, narrow floral tube (2 to 4 inches), slightly swollen only at top. Broad spathes, enclosing floral tube. Style crests very long and narrow, only slightly bent upward. Standards often spread outward. Thin, fragile-looking cream color flowers, with reddish-brown veins. Slender, light green leaves, with reddish pigment toward base. (D. Kramb, 05-JAN-04)

Preferred Habitat:

Roadbanks, meadows and similar exposed, sunny sites in pine/fir woodlands. (D. Kramb, 05-JAN-04)
