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.
