The descriptive text, below the map, is from the Cornish Red Data Book (2009). The map on this web page depicts the organisms distribution and shows the records made pre-2000 and those made since.
Range & Status
(syn. B. pyriferum Crundw. & H.Whitehouse). Collected in the Isles of Scilly by the late
R.A. Finch in 2005 and identified by C.D. Preston (Preston & Finch, 2006). This remains the only British locality for a species that is likely to be an accidental introduction. It is otherwise known in Europe by a few records from S. Portugal, S. Spain and the Canary Islands, with a wider range in N. Africa (Libya, Sudan) and N. and S. America.
Known only from two small fields on St. Agnes.
Habitat & Ecology
Found only on acidic, sandy soil in traditionally managed flower fields.
Abandonment of the flower fields or changes to the traditional style of management (see Preston & Finch, 2006) may pose threats.
