Butterfly-bearing Biscuit-root, Butterfly-bearing Desert Parsley
Lomatium papilioniferum
Synonym: Lomatium grayi, in part
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.
