Reports of Cotoneaster simonsii from Ohio (M. A. Vincent and A. W. Cusick 1998; T. S. Cooperrider et al. 2001) are here referred to C. divaricatus. The binomial C. symondsii T. Moore was proposed as an earlier name for C. simonsii (A. Kumar and G. Panigrahi 1992; W. B. Dickoré and G. Kasperek 2010), but J. Fryer and P. F. Zika (2014) typified C. symondsii so that it is a synonym of the high Himalayan species C. marginatus Lindley ex Loudon.
