The usually free sepals are more or less equal and are usually 3 veined. The petals are single veined and have entire to erose, glabrous to papillose margins. The mobile, undivided, fleshy lip is on a thin ligament, the column stigma is often proximally protruding and the column foot is with or without an apical dorsal tooth. The stelida are often with a dorsal tooth along the upper or lower margin. The anterior suface of the anther is concave or not and the anterior margin can be drawn out into a beak or not and there are 2 or 4 pollina.

There are only 2 species in this section confined to Sulawesi at elevations up to 1200 meters within montane forests.
