Comments: San Felipe Dogweed is both a Mojave and Sonoran deserts species. Through its numerous resin glands this species emits a pungent rather unpleasant odor.

At a quick glance San Felipe Dogweed looks superficially like its closely related cousin Odora, Porophyllum gracile, which has significant differences in the flower head. They both have strong disagreeable odors.
