Great show: thanks for sharing pics.
Looks like a hybrid between Arachnis (probably flos-aeris) and Vandopsis lissochiloides (thus the purple on the back of the flower). I only know of Vandachnis Coronation, a hybrid of Vandopsis lissochiloides x Arachnis Maggie Oei. Maybe a new hybrid ...Photo 1: I think it's an Arachnis. Interesting with its bright pink reverse
