|discussion=<p>Varieties 4 (4 in the flora).</p><!--
--><p><i>Crataegus schuettei</i> ranges from Wisconsin through the southern Great Lakes to southern New England, to North Carolina. Recent discoveries add the Ozarks and may add Minnesota (see discussion under <i>C. fluviatilis</i>) to the documented range. Variety schuettei closely resembles <i>C. macrosperma</i>, differing principally in its often larger flowers, 20 stamens, usually glandular-serrate sepal margins, and larger fruit but is not nearly so variable as <i>C. macrosperma</i>; the other varieties are very rare. Still, the four varieties are fairly distinct. <i>Crataegus</i> basilica appears to be the southern form of the type variety and is very like sympatric <i>C. macrosperma</i> except for stamen number.</p>
