This is another insect-trapping orchid. The "spring" to which the lip is attached can be clearly seen and when an insect lands on the lip it flips up after a few seconds trapping the insect for the purpose of pollination. These odd flowers are from Ecuador and are slightly over a half inch in size. There are more pictures of the flowers with the lip "closed" and of the plant at the link below.
