Description from Jepson Desert Manual: Odor unpleasant. Leaves strigose-canescent Ray flowers fertile (that is bad, but the keys in Arizona Flora indicate otherwise).
Strigose is hairs laying flat on the surface. The top of the leaf is like this, the underside is much more dense, and I would call it canescent.
