I don't agree. The orchid in question looks more like Elizabeth Anne then the couple you have suggested. Look at the flower count for one. Vegetatively they are different as well. The length of the tails on the Elizabeth Anne that we are struggling with are much longer then those two Meen crosses.
The Orchid Wiz program and the AOS awards program provide literally dozens of images of Elizabeth Anne and the huge majority of them match up with this unknown. They are so very similar, it is uncanny!
@Australis brought this to us just to confirm, if we could, that this was an Elizabeth Anne or was it something else.
Now I am not a taxonomist! I am not a species expert and I am not any kind of certified expert on orchid species identification but I do have over 45 years of orchid experience. I would imagine that my exposure to orchids is rather vast both as a grower, club member and judge. This "Elizabeth Anne" or whatever she is, is a hybrid within this part of the genus Bulbophyllum. It is 100% a by product of B. rothschildianum, longissimum, Elizabeth Anne, Lovely Elizabeth grouping. It is not from the Bulbophyllum bicolor, Bulbophyllum fascinator group.
If you scroll up within this post, look at Ursula's image of this hybrid with all of those spikes!! That is so typical of Elizabeth Anne!!
But Australis, I have thought about this a bit and I thought of something else. BUT it in no way changes my opinion that this unknown is a Buckleberry. I grew this like I said for a number of years and a few times my biggest clone bloomed with 8-10 inflorescences. But never did it have more then 3 or 4 flowers per! Not once!!!
Now that is my culture, my plants. If you look at arctangent's images, it has more flowers per inflorescence. A great many of the awards average 3.5-4.25 per. But is flower count enough to question the validity of arctangent's hybrid? In my opinion, that is a NO!!!
It is thought provoking though.
