Hi David. I let my subscription laps at DG just this year. Since I won't post photos, it seems a waste.
I'm afraid the real identity may never be known. Wrong cultivars/species are being sent around even more so now. Every year I discover more plants that I have that have been misidentified by the source, not just lilies.
Really, I look at all the L. henryi type blooms nowadays, and I'd rather just think of them as a henryi/rosthornii complex. So many have been bred to such extremes, yet still are derived from only these two species, or even from each separately, yet do not look at all like anything one might find in the wild. No one would think of modern zinnias as a wild species; similarly, it is my opinion that these modern bred henryi, rosthornii or henryi/rosthornii seedlings be in the same category.
It is interesting (and even more confusing) to note that in the Flora of China, L. henryi is only orange, while L. rosthornii can be orange or yellow.
