False mayweed (Tripleurospermum inodorum) is currently known in the Boise Front only from Hubbard Reservoir.  It superficially resembles the somewhat more common true mayweed (Anthemis cotula), but has more finely divided leaves, distinctively 4-angled achenes, and no spike-like bracts on the receptacle.
