Discussion
Crataegus pinetorum is found from south-central Mississippi through Alabama to northern Georgia; it appears to be scarce. The species is most similar to C. pulcherrima, differing in its sharply, rather than obtusely, lobed leaves, often densely glandular petioles, exceptionally small leaf marginal teeth and red pomes. The species also somewhat resembles the more deeply incised forms of C. gilva.
