Euphorbia hyberna in England: native or naturalised?
Keywords:status; Cornwall; Devon; Lusitanian; horticulture
Most modern authorities have considered Euphorbia hyberna to be native in Britain but with the possibility that it could have been introduced from Ireland. The results from a literature survey, on the historical occurrence of the species, strongly suggest that it was introduced and has become naturalised at a few locations in south-west England.
