Dendrobium alaticaulinum

A high-altitude Dendrobium of New Guinea, described in van Royen's Alpine Flora of New Guinea and recorded between about 2400 and 3100 m. It is a genuinely cold-growing orchid: cool days, cold nights and near-constant moisture. Few growers keep it, and details come mainly from its measured climate.
