Those are pretty outstanding, Roy. I like how the yellow lip almost seems to glow. I will be interested to see how long they last in bloom--so please provide an update, if you would, once the plant has gone out of bloom. Congratulations on the flowers. They're quite attractive in shape, color combination and presentation.
Steve, the flowers on both plants of this are falling as of yesterday. My D. thyrsiflorum, all flowers dropped, gone, finished as of yesterday. (Thursday here).
