You can certainly see the hirsutissimum. But I don't think I would have ever guessed the suk. The leaves are incredibly mottled for a hybrid involving hirsutissimum. Sukhakulii seems to have dominated for that at least.
Wow! Yeah, I'd agree the hirsut is obvious, but if I'd had to guess I would have maybe thought wardii rather than suk from the flower color - cool cross! 3 flowers open at the same time And stunning blooms is great
