This has to be one of the most wickedly cool looking orchids that I grow. Flowers are reasonably strongly scented of butterscotch/buttered popcorn at night. They bloom sequentially on very thin, wiry spikes sheathed in dark brown sheathing. This renders the spikes virtually invisible from any distance. Mature plants can have dozens of spikes, giving the appearance of a flock of green ghostly goblins bobbing about in thin air. Mine is a rather young plant with only two extant spikes:
