Crataegus delawarensis, commonly known as the Delaware hawthorn [3] was a hawthorn species endemic to northern Delaware. [4] Crataegus delawarensis can be differentiated from other members of its series by its narrower leaf blades and yellow anthers. [4] It was a tree-like shrub that could grow up to 30 ft. in height. [3] There is only one known occurrence between Newport and New Castle, Delaware. Despite searches, Crataegus delawarensis has not been seen since 1903. [1] Due to its limited range and intermediate characteristics, Crataegus delawarensis is assumed to have been of hybrid origin between Crataegus pruinosa and C. populnea . [5]
