Discussion

In the flora area, Acalypa chamaedrifolia is native to Miami-Dade and Monroe counties but has been sparingly, and apparently accidentally, introduced farther north.

Plants from the United States have nearly always been called Acalypha lindheimeri, distinguished from A. phleoides on the basis of leaf shape and bract lobing. Although plants from Texas generally can be distinguished from plants from central Mexico southward, plants from intervening regions in the United States and Mexico include a full range of intermediates (G. A. Levin 1999b).
