Mediocalcar decoratum

This little orchid is one of my favorites for its brightly colored, candy-corn-like flowers.  The individual growths are only 2cm but grow on top of each other, so the plant tends to ramble.  The growths have little cylindrical pseudobulbs with three or four fat little leaves at the top of each like a little propeller.  It prefers cool temperatures and good humidity but is easy to grow.  It is from New Guinea and belong to a small genus of plants that have similar brightly colored flowers, but plant that are in some cases much larger than this.
