• Spine-tipped leaves
  
• Sap toxic and an irritant to people and possibly also animals

• Seeds dispersed by dehiscent capsules and people (but possibly rarely produced)
  
• Limited ecological information from native and introduced ranges makes accurate risk predications difficult

Low Risk Traits:
