Crataegus beata is a rare, variable taxon that here comprises all the 20-stamen forms of ser. Populneae and may be more widespread than indicated. Syntype material has resemblances to C. schuettei and C. stolonifera. The very small amount of material available to the author is characterized by tan or very dark (brownish to blackish) one-year old wood and one-year thorns, sharply dissected, narrower, C. levis-like leaves, or more shallowly incised (except in extension shoots) C. populnea-like coriaceous foliage and glandular-serrate sepals. In these, the anthers are pink to red and the pomes large, oblong-orbicular, and red. The young leaves are densely short, scabrous hairy adaxially when young.
