Discussion

Crataegus spathulata is locally common across the southern states from southern Missouri to Virginia south to eastern Texas to Florida.

Mature Crataegus spathulata has very attractive, often honey-colored, exfoliating bark. The illustration herein depicts an atypically large, unusually shaped, herbaceous bracteole.
