Shrubs, sprawling, 0.5(–1.5) m.

Cotoneaster hodjingensis sometimes is synonymized with C. buxifolius Wallich ex Lindley (Zhou L. H. and Wu Z. Y. 2001; L. Lingdi and A. R. Brach 2003), a species from southern India with elliptic to ovate-elliptic, usually obtuse (rarely short-acute) leaves to 17 mm, petioles to 4 mm, 1–9 flowers per inflorescence (to 20 on end shoots), and a tomentose hypanthium. Here, C. hodjingensis is treated as separable by its normally narrower leaves no longer than 11 mm, usually acute, with petioles to 2 mm, solitary flowers (2 or 3 flowers per inflorescence on end shoots), and villous hypanthium becoming glabrate (G. Klotz 1963).
