: rotundifolia, Michx. ? (C. rhomboidea, DC. var. purpurea, Torr.) 
Our plant does not agree with the description of C. rotundifolia 
in Gray’s Manual, nor with specimens from Penn. Nor is the 
plant likely to be C. pzspurea, Cham & Schlecht., which seems 
to be a species growing far northward. In giving it Michaux’s 
name, we follow Watson, but with much doubt.
