Lvs sessile or subsessile, 3-8 × 0.5-3 mm, elliptic but appearing linear because of revolute margins, densely hairy, with abundant oil globules, tomentose along midrib below.

Calyx 3-4 mm long, campanulate, green or purplish, hairy, dotted with oil globules, with tuft of white hairs in throat; teeth of upper lip ovate, not ciliate; teeth of lower lip linear-subulate, long-ciliate. Corolla 4-6 mm long, white or mauve; tube not exserted, hairy outside; upper lip with large, broad, oblong-elliptic to obovate lobes, sparsely hairy or glabrous; lower lip at right angles to upper. Stamens not or scarcely exserted; anthers purplish. Nutlets 6-8 mm diam., broad-ellipsoid to sub-spherical, dark brown.
