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 rivuloadamensis is known only from the western half of the Cypress Hills and is most abundant at elevations above 1150 m. The extremely dark young wood and short and conic thorns show strong resemblance to species of the Eurasian sect. Sanguineae Zabel ex C. K. Schneider. The unpitted pyrenes are a marked difference. The petals appear to be pale cream rather than pure white. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
