Facts
Crataegus handyae is a very rare hawthorn in New England. It is intermediate in morphology between C. macracantha and C. pruinosa, which suggests it may be of hybrid origin.
Habitat
Anthropogenic (man-made or disturbed habitats), forest edges, forests, meadows and fields
New England distribution
Adapted from BONAP data
Native: indigenous.
Non-native: introduced (intentionally or unintentionally); has become naturalized.
County documented: documented to exist in the county by evidence (herbarium specimen, photograph). Also covers those considered historical (not seen in 20 years).
State documented: documented to exist in the state, but not documented to a county within the state. Also covers those considered historical (not seen in 20 years).
Note: when native and non-native populations both exist in a county, only native status is shown on the map.

18. Crataegus handyae Sarg. NC
Handy’s hawthorn. Crataegus chadsfordiana Sarg.; Crataegus spatiosa Sarg. • CT, MA. Fields, forest borders, roadsides, early successional forests. This rare taxon appears to be derived through hybridization between a member of series Macracanthae (e.g., Crataegus macracantha) and a member of series Pruinosae (e.g., C. pruinosa). Most of the collections shows non-anthocyanic anthers; however, rare collections show anthocyanic anthers. Though these collections were considered synonymous by Sargent (under the name C. chadsfordiana), they are better treated as a new variety but are currently lacking a published name.
Native to North America?
Yes
Sometimes confused with
- Crataegus umbratilis:
- flowers with 12-20 stamens with anthers mostly 1.8–2.3 mm long (vs. C. handyae, with flowers with 5-10 stamens with anthers 1.2-1.5 mm long).
- Crataegus macracantha:
- leaf blades sparsely to moderately pubescent adaxially during flowering and pyrenes with deep excavations on the inner surfaces (vs. C. handyae, with leaf blades leaf blades glabrous or very sparsely pubescent adaxially during flowering).
Synonyms
- Crataegus chadsfordiana Sarg.
- Crataegus spatiosa Sarg.
