Discussion

Cotoneaster crispii was collected recently wild in Yunnan. The species is often treated as a hybrid of garden origin between C. frigidus and C. pannosus. Plants of it differ from those of C. frigidus in their smaller and persistent leaves, and it has larger leaves and fruits than C. pannosus. The species was overlooked in the Flora of China (L. Lingdi and A. R. Brach 2003).
