Description

Erect herbs, 20-30 cm tall. Stem subquadrangular, grooved and rounded on angles, puberulous to glabrescent. Branches decumbent, rooting at lower nodes. Petiole 4-5 mm long, puberulous; blade membranous or chartaceous, ovate or ovate-oblong, 30-55 x 15-25 mm, glabrous, acuminate at apex, abruptly contracted into petiole; primary vein and secondary veins (4-5 pairs) shortly and sparingly adpressed pubescent.
