Discussion | G. Klotz (1963) emended the diagnosis of Cotoneaster conspicuus to recognize erect plants as var. conspicuus and more decumbent plants as var. decorus. This variation in habit is not significant taxonomically and not unusual for an outcrossing diploid, so the emended description by Klotz of the species is superfluous.
