Discussion | Pluchea foetida var. imbricata has not been treated as distinct from typical P. foetida by recent authors (e.g., A. Cronquist 1980; R. K. Godfrey and J. W. Wooten 1981; R. P. Wunderlin et al. 1996). Although plants similar to the type can be found scattered in Florida and Georgia, a populational integrity does not appear to occur, and intermediate forms exist. Nevertheless, field biologists should be aware of the putative distinctions of var. imbricata to make more critical observations regarding its status.
