Ecological impact detail
The establishment of species closely-related to threatened endemics is highly undesirable, due to the risk of hybridisation (in this case with Ascension Island spurge E. origaniodes). (Lambdon, P. & Darlow, A. (2008) Botanical Survey of Ascension Island and St. Helena 2008. RSPB);
