Maxillaria sophronitis

Also known as Ornithidium sophronitis, this small creeping plant is known for its brightly colored red-orange flowers.  The tiny growth, each with a little pseudobulb, sheathing leaves and a single leaf at the top of the pseudobulb, is less than 5 cm and the single flowers are only 1.5 cm.  The species is from Colombia and Venezuela and requires cool temperatures and high light.  Even then I find it hard to get it to bloom with more than a few flowers at a time.
