Flowers 10–20 mm diam.; hypanthium glabrous; sepals narrowly triangular, margins glandular-serrate, abaxial surface glabrous; stamens 10, anthers cream, sometimes pale-pink; styles 3–5. Pomes pale orange, strongly pruinose, or deep red, suborbicular, 10 mm diam., glabrous; flesh soft when mature; sepals patent-reflexed; pyrenes 3–5, dorsally grooved, sides plane.

Discussion

Crataegus ×sicca is a poorly understood taxon from scattered locations in southern Missouri and southern Ohio. It is likely an interserial hybrid between C. margarettae and one or more entities in the C. pruinosa complex.
