SUBGENUS Ancipitia SECTION Ancipitia Luer 1986

Characterized by the sharply laterally compressed, ancipitous ramicauls except in one species that is 4 angled, the cordate and sessile leaves and the long pedicellate single flowers produced in a fasscile at the base of the leaf without an annulus. The sepals are more or less membraneous with the laterals connate. The petals are thickened towards the apex and the lips are diversely modified, often into bizarre shapes resembling insect and animal horns and ears. The morphology of the some parts of the flowers is quite variable among the species but the ramicauls, leaves, peduncles, sepals and petals are quite consistently the same.
