I recently picked up this nifty little guy from Al Pickerel. It is a miniature species named Dendrobium gonzalesii. Its a skinny plant about 6 or 7 inches tall with nobby stems (photo below). My plant is a seedling blooming for the first time on a leafless cane, so it may actually get little taller in the coming years.
