Flowers solitary in axils of deciduous bracts on new shoots. Pedicel ca. 1.5 mm. Flowers scaly outside, scales mostly silvery, some brown. Calyx tube campanulate, ca. 3 mm; lobes broadly ovate, both surfaces with rust-colored and silvery scales. Filaments very short; anthers ellipsoid, ca. 2 × as long as filaments.

● On rocks. Sichuan.

The placement of this species is very uncertain, as the leaf blade is said to be stiff and leathery but also deciduous, and there is no information on the time of flowering. The very small, Buxus-like leaves seem distinctive.
