Discussion

Of conservation concern.

Crataegus nitida is found from southern Illinois to eastern Arkansas along the Mississippi River flood plain; it appears to be rare. The species differs only slightly from C. viridis var. viridis, mainly in the larger fruit, more pronounced leaf marginal teeth, and more coriaceous mature leaves. Horticultural plants labeled C. nitida are usually a C. crus-galli × C. viridis cross.
