Dendrobium pentapterum is another Oxyglossum Dendrobium from New Guinea. The plant is 10 cm tall with 3 cm pale green flowers that have an bright orange tip to the lip. Its most remarkable feature however, is its floriferousness. It has as many as four flowers at a time from each growth that last up to six months and it continues to bloom from the older growths over many years. My plant at present is in an 8 cm clay pot and has over 80 flowers on, so crowded that it is hard to see where one ends and another begins. I had thought about taking it in for judging but discovered that another plant had been awarded with 170 flower, mine not even having half that amount.
