Description

Herb to 40 cm high. Stem subquadrangular, sulcate, densely to sparsely hirsute to glabrescent, cystoliths inconspicuous. Leaves sessile to subsessile; blade linear to narrowly lanceolate, to 6.5 cm long and 1.2(-1.5) cm wide, acute to obtusish (tip itself blunt), narrowed at base, both surfaces densely to sparsely hirsute; primary vein and secondary veins (5-8 pairs) usually prominent on lower surface; cystoliths obscure. Inflorescence of sessile, solitary or paired flowers in axils of terminal leaves, often opposite; bracts 0; bracteoles linearto 6.5 mm long and 0.8 mm wide, hirsute.
