Broadleaf Hawthorn

Crataegus dilatata

Some members of the Crataegus genus are challenging to classify and identify because of the tendency to hybridize – over 1200 entities of Crataegus have been identified. C. dilatata has been viewed as a variety of C. coccinioides but it is classified as a separate species based on differences in its fruit and flower structure.
