Discussion
Cotoneaster magnificus was synonymized with C. multiflorus Bunge by L. Lingdi and A. R. Brach (2003). Flowers of the latter are 9–10 mm wide in clusters of 10–20, the flowering pedicels are to 7 mm, and the leaves are smaller, thinner, and tend to be ovate. Plants of C. magnificus have flowers 12–14 mm wide in clusters of 5–12, flowering pedicels are to 12 mm, and the leaves are larger, thicker, and mostly elliptic. Reports of wild C. multiflorus from Illinois (F. Swink and G. S. Wilhelm 1994; J. T. Kartesz and C. A. Meacham 2003) and Iowa (W. R. Norris et al. 2001; Kartesz and Meacham) are referred to C. magnificus.
