My Mtssa. Shelob 'Tolkien' now in orchid heaven in dark and light color.
My experience with distortions is that growing in less than optimal conditions can cause it and it can be fine the next bloom period. But pelorics may be an exception. I'd say you wont know till the next bloom period for sure.
Here is an example. Laelia lundii x Epi. longipetalum. Last Feb. it grew lots of strange shaped flowers. And look at the blooms now. Actually, I'd like one of each thank you!
