The Labellum is large and conspicuous. It is covered all over with hairs, which begin as bead-like Calli at the top , becoming longer towards the tip. The tip is extended into a slender strap, but this is still covere with hairs. The Column is broad, green in colour and has two conspicuous red Glands on either side of its base.
