Discussion

Crataegus attrita is known only from southeastern Mississippi (Lowndes County), southeastern Alabama (Dale and Greene counties), and adjacent Florida (Washington County). It is most similar to C. florens and C. teres and is more or less intermediate between the two; its dense tufts of hair in the abaxial vein axils are reminiscent of C. aestivalis.
