Leaves simple; petiole 7–10 mm, pubescent, with sparse, curved minute prickles; stipules free, brown, oblong-lanceolate or elliptic-lanceolate, 1–1.4 cm × 3–5 mm, margin entire or sparsely shallowly serrate; blade oblong-lanceolate, 7–13 × 2–3 cm, lateral veins 8–11 pairs, prominent abaxially, abaxially sparsely pubescent only along veins, with remote curved minute prickles along midvein, adaxially glabrous except pubescent along midvein, base rounded, margin coarsely sharply serrate, apex acuminate. Inflorescences terminal or axillary, narrow cymose panicles, few flowered, axillary ones shorter, or flowers few in clusters; rachis and pedicels pubescent, with sparse, curved minute prickles; bracts similar to stipules but sometimes apically lobed; lobes linear to lanceolate, apex acuminate. Pedicel 5–8 mm. Flowers 7–9 mm in diam. Calyx abaxially pubescent; sepals ovate-lanceolate, margin tomentose, apex acuminate; outer sepals often laciniate at apex, lobes lanceolate or linear, inner sepals entire.
