Discussion

Crataegus buckleyi is pink-anthered like C. neobushii, but its leaf form is more like that of the common forms of sympatric C. intricata (cream anthers). Beadle suggested on some herbarium labels that C. buckleyi is usually a larger plant than the former, has relatively later anthesis, and stipitate glands along the proximal margins of the calyx. Crataegus communis is a related form with a more broadly elliptic leaf and stems only 10–20 dm.
