Discussion

Fleischmannia sonorae was reported for Arizona by T. H. Kearney and R. H. Peebles (1960) and F. Shreve and I. L. Wiggins (1964) as Eupatorium pycnocephalum Lessing [= Fleischmannia pycnocephala (Lessing) R. M. King & H. Robinson)]; revised concepts of this species group (B. L. Turner 1996+, vol. 2) place F. pycnocephala as a related species in Mexico and Central America, not reaching northwestward to Arizona.
