Calyx of 5 linear sepals, 4-10 × ca. 1 mm, ciliate with stiff hairs.

The Chinese specimens were previously named as Abelia buddleioides by W. W. Smith (Notes Roy. Bot. Gard. Edinburgh 9: 75. 1915-1916). The type specimen Forrest 12636 from Yunnan is similar to the type of A. triflora var. parvifolia (Clarke) Hisauchi & H. Hara from Pakistan. Nevertheless, the group shows much variation in the size and shape of the leaves and sepals.
