| CAYUGA FLORA (1926) NOTES: Dry fields, roadsides, and waste places, in various soils; very common. Aug. 15-Sept. 15. N. S. to B. C, southw. to Fla. and Mex., including the Atlantic Coastal Plain. The native range is now obscure, but the species was probably not indigenous east of the Allegheny Mts. This plant is believed to be the principal cause of autumnal hay fever. The pollens of this and other species of Ambrosia, as well as that of Iva, are equally virulent. |
