A perennial 10–50 cm tall, growing at the edges of woods in hilly areas.
The stem stands erect from a short underground stem and is densely covered with downward-pointing hairs.
Leaves are simple and opposite, 1.5–5 cm long and 1–4 cm wide, broadly ovate to triangular-ovate, with wavy teeth on the margin.
Both surfaces of the leaves are fairly densely covered with soft hairs.
The upper leaves are larger and have glandular dots on the underside.
The leaf stalk is 1–2 cm long.
A short raceme at the stem tip bears flowers in pairs, turned to one side.
The inflorescence adheres to the upper leaves.
The corolla is pale purple and about 2 cm long; it is a lipped flower whose tube bends at the base and rises upward, with a hood-shaped upper lip and a 3-lobed lower lip.
