Ambrosia bidentata Michx.
Isolated populations of this Midwestern ragweed occur in the Virginia, North Carolina, and South Carolina Piedmont on soils (especially hardpans) weathered from mafic or calcareous rocks. However, the plants generally occur in weedy habitats, and it is not clear whether they represent non-native or native, disjunct populations. Recently discovered in the outer Coastal Plain of Virginia (York County).
Fields, clearings, and roadsides, especially on calcareous metasedimentary and mafic substrates. Rare (but locally common) in the s. Piedmont and c. Coastal Plain.
