Discussion | Crataegus holmesiana ranges from Wisconsin and Illinois through the southern Great Lakes region to southern Quebec and Maine, and to Pennsylvania; it is common in much of its range and should be expected in West Virginia. In its usual form, Crataegus holmesiana is readily distinguished from C. coccinea vars. coccinea and pringlei, though occasional intermediates occur. Crataegus robesoniana Sargent [C. pedicellata var. robesoniana (Sargent) E. J. Palmer] is one and perhaps C. amicta Ashe [C. holmesiana var. amicta (Ashe) E. J. Palmer] is another. Crataegus holmesiana is routinely interpreted as a typical member of ser. Coccineae, thus, a villous inflorescence taxon with serrate sepals. However, the protologue by Ashe (authentic material not located) states that the inflorescences are glabrous and the sepals are nearly entire, causing confusion with C. tenuifolia Britton (ser. Tenuifoliae). Current usage for C. holmesiana became fixed after Ashe erected a var. villosa with serrate sepals and villous inflorescences.

Crataegus floridana is frequent in north-central Florida and extends through much of Georgia with single records from Kershaw County, South Carolina, and Brunswick County, North Carolina. Crataegus floridana resembles C. quaesita in its more or less obtrullate, but distally lobed leaves (which can always be observed fluttering in the wind) and longer petioles. The largest leaves in subser. Tenues may be found in Crataegus floridana; there is considerable size variation. The depth and sharpness of the lobes is variable, with a maximum in the proportionately broadest leaves, these having been called C. anisophylla. Differences from 146. C. meridiana are noted there.
