Crataegus aestivalis (Walter) Torrey & A. Gray. Eastern Mayhaw. Phen: Mar-Apr; Jun-Jul. Hab: Swamp forests, generally where flooded for much of the year, often flowering and fruiting while standing in water, often associated with Taxodium distichum, Nyssa aquatica, Nyssa biflora, and Planera aquatica, uncommon but sometimes locally abundant; occasionally growing as groves or stands in ‘mayhaw flats’. Dist: Se. NC south to n. FL and se. AL. A historic report of C. aestivalis in VA appears to be based on a single specimen collected 22 July 1934 by M.L. Fernald & B. Long, in Princess Anne County; this specimen is actually C. crus-galli.
