Crataegus collina

Crataegus collina is a type of hawthorn that is closely related to C. punctata, the dotted hawthorn, and sometimes considered to be the same species. A sample of C. collina and C. punctata has suggested that C. collina is polyploid, and C. punctata is diploid, but a wider sample is needed to confirm that this is generally the case.
