Discussion

Varieties 2 (1 in the flora).

Crataegus monogyna was introduced early to North America to be used for agricultural hedges, a practice now discontinued on this continent.

Cultivar 'Crimson Cloud,' often under an incorrect species name, is widely cultivated as an ornamental.

Crataegus furtiva is concentrated in Georgia and South Carolina with records from Alabama, Florida, and North Carolina. The species, as it is usually seen, has among the smallest leaves of the thick-twigged group (subser. Robustae) and is one of the most densely hairy of all members of ser. Lacrimatae when young. Its usually wide, obtrullate leaves are distinctive. The type form, which is also common, represents a narrower-leaved form. In spite of some variability in leaf shape and fruit size, shape, and residual indumentum, C. furtiva is usually easily recognized.
