I. bracteata: Perianth cream to buff-yellow; floral tube (4)8-9(10)mm; sepals width (15-)25mm; petals (7)8-15(20)mm wide; basal leaves (4)8-10(18)mm wide, many; (1)3-6 cauline leaves imbricate, bractlike; growing in shady forests;

I. innominata: Perianth usually dark golden yellow, cream, pink, lavender, or purple; floral tube 15-26(30)mm; sepal width (15)17-26(30)mm; petals (8)9-14(16)mm wide; basal leaves (2)3-4(6)mm wide; (1)2-3(4) cauline leaves; growing in sunny to partly shaded woods.

Now here's my reasoning...perianth color of either species fits these plants (due to variability of innominata), but seems a better match for typical bracteata, as does the habitat. I didn't take absolute measurements in the field, but can measure relative length from my photos. From the description info, the ratio of sepal width to floral tube length ranges roughly from 2.5-3.75 for bracteata vs approximately 1 for innominata. I measured the ratios in three flowers visible in the images to be: 1.7, 2.1, and 2.2. Also, the ratio of petal width to basal leaf width ranges roughly from 1.1-1.75 for bracteata vs 2.7-4 for innominata. Measurements from my photos are closer to bracteata here. Also note that at the end of the JM2 description of innominata they remark that that species ''may not occur in CA'' and it is ''sometimes confused...with narrow leaf forms of Iris bracteata''. As far as number of cauline leaves, my images don't show any complete stems...but I counted 4 imbricate cauline leaves on the visible portions of two stems. That's consistent with both descriptions but 'more so' with bracteata (at least in JM2).

PS: If any north coast CNPSer's and/or botanists know these two species well and can confirm or correct me here, I'd appreciate your input!
