Shrubs, 30–50 dm. Stems: twigs: new growth reddish early, glabrous, 1-year old deep tan, 2-years old tan to deep reddish brown, older dull gray; thorns on twigs at 1-year old shiny, dark brown to nearly black, stout or slender, 4–6 cm. Leaves: petiole slender, length 40–60% blade, sparsely pubescent or glabrous, eglandular or sessile-glandular; blade short-ovate to ovate, broadly elliptic to narrowly rhombic, or ± trullate, 3–8 cm, base rounded to cuneate, lobes 3–5 per side, margins serrate, veins 5–7(or 8) per side, apex acute, abaxial surface glabrous, adaxial sparsely to densely appressed-pubescent young, glabrescent. Inflorescences 6–10-flowered; branches glabrous or villous. Flowers 15–18 mm diam.; hypanthium glabrous or pubescent; sepals narrowly triangular, margins subentire or glandular-serrate; stamens 7 or 8(–10), anthers pink; styles 3 or 4. Pomes reddish or orange-red, suborbicular, 6–9 mm diam., pruinose, glabrous or slightly pubescent; sepals spreading to ± erose; pyrenes 2–4, sides often pitted. 2n = 51.

Discussion
Varieties 4 (4 in the flora).
Crataegus scabrida is variable in leaf shape and size, as well as in pubescence of adaxial leaf surfaces and pedicels. The species falls into four reasonably well-marked varieties, only the first two of which are frequent. The range of the species as a whole is somewhat poorly documented because of frequent incorrect identification.
Selected References
None.
