Crataegus wattiana is the only Asiatic hawthorn known to have escaped from cultivation in North America. The species is one of the relatively few usually yellowish-fruited hawthorns.
The depth of sinuses of the leaf blades in Crataegus wattiana is variable, ranging between 3 or 4, more or less equally shallow to moderately deep lobes per side to deeply incised at the proximal two sinuses.
