Shrubs evergreen to semievergreen, 1–2 m tall. Leaf blade elliptic to elliptic-obovate, 5–10 mm or slightly longer, abaxially gray tomentose, apex usually acute and mucronate. Inflorescences 3–5(–9)-flowered, rarely flowers solitary. Pedicels, hypanthium, and sepals abaxially densely and persistently strigose-tomentose.

Zhou & Wu (Acta Bot. Yunnan. 23: 29–36. 2001) treated Cotoneaster buxifolius f. vellaeus as a synonym of Cotoneaster poluninii G. Klotz (from Nepal) and recognized C. delavayanus G. Klotz as a distinct species. Although sometimes aligned here, we consider both Cotoneaster astrophoros J. Fryer & E. C. Nelson and C. delavayanus as doubtful species.
