Spikes subcapitate, 1-2.7 cm × 8-9 mm; bracts purple, lanceolate, slightly longer than calyx, margin gray villous. Calyx ca. 1 × 0.8 mm, pilose, glandular, 5-sulcate. Corolla reddish, ca. 2 × as long as calyx. Stamens much exserted. Nutlets unknown.

Aquatic, marshy streamsides; 900-1500 m. Yunnan [India]

Specimens from Yunnan do not have the slender, erect stems and slender spikes as described by C. B. Clarke for Indian plants. This may be due to local variation.
