Dendrobium sulphureum var. sulphureum

This is another high-altitude species from New Guinea in the Oxyglossum section of Dendrobium.  Like most of the other plants in the section, it needs cool temperatures, good light and humidity, and also like the species in the section has triangular flowers in bright but unusual color combinations, in this case, pale yellow flowers with a dark green column and an orange mid-lobe.  The canes are 13 cm long and the 3 cm flowers come two or three at time and last many months.  Even after the leaves fall from the canes they continue to produce flowers.
