|discussion=<p><i>Crataegus ×collicola</i> and C. ×verruculosa are two different putative hybrids, both of which are expected to possess parentage suggested by E. J. Palmer (1952) of <i>C. collina</i> and <i>C. crus-galli</i>. <i>Crataegus ×collicola</i> has thorns 4–8 mm, young twigs glabrous, leaf blade broadly elliptic to obovate, 2 or 3 lobes, and 4–6 veins per side, glabrous inflorescence branches, entire sepal margins, and pomes orange to dull red, depressed orbicular, and 8–11 mm diam. <i>Crataegus</i> ×verruculosa has thorns 2–2.5 mm, young twigs hairy, leaf blades narrowly obovate, unlobed, veins 3–5 per side, hairy inflorescence branches, sparingly glandular-serrate sepal margins, and pomes dark red, orbicular, 10–13 mm diam. If these are considered to be the same hybrid species, separate nothovariety names should be erected to maintain distinction.</p>
