Dendrobium oreodoxa x cuthbertsonii

I purchased this hybrid several years ago and as far as I know it is still unnamed.  It is a hybrid of the micro-miniature Dendrobium cuthbertsonii from section Oxyglossum and the much larger cane-type Dendrobium oreodoxa from section Calyptrochilus, both species from New Guinea.  The hybrid seems little influenced by the Dendrobium oreodoxa parent.  Both plant and flowers look like the other parent, Dendrobium cuthbertsonii.  The individual growths are less than 3 cm and the flowers are nearly 4 cm long.
