Crataegus ×mohrii Beadle. Mohr’s Hawthorn. Phen: May; Sept.-Oct. Hab: Hardwood and pine-hardwood forest understories. Dist: Rare and sporadic from MS to GA, n. to TN.

Origin/Endemic status: Endemic

Taxonomy Comments: The combination of short (2-4 cm), suborbicular terminal shoot leaves and 3-5 styles suggests an affinity to C. reverchonii Sargent, as per Phipps (2014d); alternatively, C. ×mohrii could be considered an intraserial intermediate of C. reverchonii and another member of Crus-galli, due to range considerations and its pilose inflorescences and yellow anthers.
