For butterfly-loving desert parsley, the individual leaf segments are generally 1-5 mm long, dagger-shaped, and a blue-gray green color. There often numerous minute glands on the leaf segments (visible with a hand lens). The foliage also often looks denser than that of Klickitat desert parsley (Lomatium klickitatense). In contrast, the leaf segments of Klickitat desert parsley are longer (6-10mm long), more needle-shaped and a glabrous green (rarely any glands on the segments). Mature butterfly-loving desert parsleys have an irregular shape and are about half (or less) the size of Klickitat desert parsley which generally has a rounded shape.

What appears to be butterfly-bearing biscuit-root as observed on scablands several hundred meters east of the east rim of Canyon Creek, Klickitat Wildlife Area. I will need to return at a later date in the season to confirm it's identity.
