Mediocalcar decoratum

One of my favorite miniature orchids, this plant produces hundreds of flowers in autumn.  The individual growths are less than 2 cm, each a fat little stem with three of four propeller-like leaves.  They grow from the top of the previous stem, however and ramble all over producing a mat of growths that soon covers a mount or spills over the edges of a pot.  The tiny, less than 1 cm, orange and yellow flowers are colored like candy corns and look like a little balloon that has exploded on one end.  The species is from Papua New Guinea and prefers cool temperatures and high humidity with good light.
