|discussion=<p>Variety vigintistamina is similar to var. chrysocarpa except with 20 stamens; it is frequent in parts of Minnesota, where it has the intermediate indumentum mentioned under var. chrysocarpa and var. faxonii. Crataegus divergens (Peck) Sargent, a prior name, with 10 to 18 stamens according to Sargent, is known from New York; its type (C. H. Peck 70) has ten stamens, preventing the name from being used for the current taxon.</p>
