⚠ Version 1.1 of The Plant List has been superseded and should no longer be used.
The new version is available at http://www.worldfloraonline.org. The new version is enhanced, using more data sources including Taxonomic Expert Networks and will be more frequently updated.
The record derives from RJP (data supplied on ) which reports it as a synonym (record 1609) with original publication details: Supplementum prodromi florae hispanicae Supplementum prodromi florae hispanicae; 1893 221 1893.
This name record (from RJP) was not included in version 1 of The Plant List. It is possible the same name was included from a different data source, to check this you can search for Crataegus boissieri in version 1 of The Plant List.
