Synonyms: C. chippewaensis Sargent C. holmesina var. chippewaensis (Sargent) E. J. Palmer C. illecebrosa Sargent
Treatment appears in FNA Volume 9. Treatment on page 560. Mentioned on page 559.

Leaf-blades broadly elliptic to elliptic-ovate, 4–7 cm (length/width = 1.2), usually plane, rarely concavo-convex, base rounded to broadly cuneate, lobe sinuses often shallow. Stamens 20. Pomes usually suborbicular.


Phenology: Flowering May; fruiting Sep–Oct.
Habitat: Brush, woodland margins, fencerows, overgrown pastures
Elevation: 10–300 m

Discussion

The leaf shape of var. fulleriana is somewhat intermediate between var. coccinea, var. pringlei, and Crataegus holmesiana. In J. A. Macklin (2001), the placement of var. fulleriana indicates it is not simply a 20-stamen variant of one of the 5–10-stamen entities. Crataegus confragosa Sargent may represent a glabrate form. Very rare convex-leaved forms might also be interpreted as mutants of var. pringlei.
