may hawthorn
Crataegus aestivalis (Walter) Torr. & A.Gray
May hawthorn belongs to the seasonally wet landscapes of the southeastern United States. Its reproductive year starts early: flowers can appear while many other woody plants are still moving toward spring. The later, rounded fruits are pomes, the same broad fruit type as apples, although here they are much smaller. The common name mayhaw connects the plant with that early fruiting season.

Recognizing the plant
Flora of North America describes flower clusters with two to four blossoms. Individual flowers are about twelve to thirty millimetres across, with pink anthers and usually four or five styles. The shiny fruits measure roughly eight to twenty millimetres and are generally red, sometimes yellow. Four or five hard seed-containing stones lie within the flesh, a useful detail when comparing related hawthorns. Flora of North America: Crataegus aestivalis
