This is another Dendrobium from the Oxyglossum group, though it does not come from New Guinea, like so many of the others. This species is native to the Molucca Islands, but comes from high elevations and requires cool temperatures. Its name, in fact, means "mountain dweller."
Each growth with its narrow leaves is about 10 cm tall and the flowers a little over 2 cm, but it blooms on the older leafless pseudobulbs and blooms during the winter. Like most of the species in this group the paired flowers are very long lasting, staying in good condition for months.
