Facts About

Yellow hawthorn is one species of Crataegus whose genetic profile has been studied in some detail, in an effort to understand its relationship to other North American and Asian hawthorn species. It is somewhat distinctive among hawthorns in that its infloresences are largely hairless.

Habitat

Anthropogenic (man-made or disturbed habitats), forest edges, forests, meadows and fields

Sometimes Confused With

Crataegus lumaria:
inflorescence and sometimes the hypanthium sparsely pubescent, and pomes obloid to obovoid (vs. C. flavida, with the inflorescence and hypanthium glabrous, and pomes subglobose to short-obloid).
Crataegus dodgei:
leaf blades on short-shoots rounded to obtuse at the apex, with rounded to obtuse lobes, usually borne on eglandular petioles, and sepals entire to weakly glandular-serrate (vs. C. flavida, with leaf blades on short shoots obtuse to subactue at the apex, with acute lobes, usually borne on glandular petioles, and sepals weakly to somewhat prominently glandular-serrate).

14.  Crataegus flavida Sarg. N

yellow hawthorn. Crataegus chrysocarpa Ashe var. phoenicea Palmer, sensu New England authors; C. dodgei Ashe var. flavida (Sarg.) P.G. Sm. & J.B. Phipps; C. grossa Sarg. • CT, MA, ME, NH, RI, VT. Fields, forest borders, roadsides, early successional forests. Glabrous forms of Crataegus chrysocarpa have long been called C. chrysocarpa var. phoenicea, a problematic name given its absence of a type. Plants labeled as this variety in regional herbaria clearly belong to a separate species (here called C. flavida) as evidenced by glabrous inflorescences and pomes, less prominent teeth on sepals, and differences in leaf blade outline.
