A description of Crataegus uniflora is provided in The Flora of North America. This species has been described as a small, tree-like, scraggly scrub.[2]
Distribution
Found from New York and New Jersey south to north Florida, west to east Texas and northeast to south Missouri.[3]
Ecology
Habitat
This species has been observed in semi open, mixed hardwood woodlands, sandy ridges, slopes, and within stands of slash pine on sandy soils. Thrives in open light and shaded environments in moist loamy soils, dry sand, and loamy sands. It also occurs in disturbed sandy soils associated with sand pine, longleaf pine, and turkey oak community.[2] However it was found to be a decreaser in its long-term response following cessation of repeated soil disturbance.[4]
Associated species includes slash pine, sand pine, longleaf pine, turkey oak, red oak, post oak, mockernut hickory, magnolia, Viburnum rufidulum, and others.[2]
