Lavergne, Christophe (2006)
"Cultivé/naturalisé"

Comments:  Invasive in northern Queensland.  "It thrives around Townsville (-15 deg. latitude) which has a comparatively low rainfall, more a dry monsoon area and rampages around Cooktown (-19 deg. latitude) where the summer rainfall can be measured in metres, giving it quite a broad climate range.  I believe that it occurs on a range of soil types.  It is most definitely an environmental weed. Given the situations I have personally observed it I believe that it would have some degree of shade tolerance in it's earlier life stages.  it will definitely reproduce by vegetative fragmentation.  Given it's distribution around Cooktown I believe that the seeds would be dispersed in floodwaters.  It is extremely likely to be bird and pig dispersed"  (Louise Hucks, Northern Australia Quarantine Strategy, Australian Quarantine and Inspection Service, pers. com.).
