C. biflorus could be an apomict. More studies on DNA level are planned. A more intensive international sampling program is set up for C. biflorus as well as A. arenaria. When molecular methods become applicable the spread from original areas of both species may be traced. It produces seeds that may be easily dispersed and wounds live stock and wildlife.
Local farmers regard the plant as a serious pest.
