Catasetum splendens (I'm stumped!)

[nancy]

Hello -
A bit of weirdness here - these flowers have just finished opening; I thought, because the buds were so very green, that the flowers would be female (last blooming was male flowers), but now that they're opened, I see that they are male. Now the weird part - the last flowers were very pink, including off-white sepals, with the petals red-spotted and the lip also pinkish-white with a very yellow center.
I have close-up photos of the flowers, if anyone is totally enthralled, but you can see looking at the two inflorescences that this year's flowers are a different color. They are also conspicuously larger...any speculation as to the reason for this? It is absolutely, positively the same plant. Only difference I can think of is that some randy insect triggered all of the pollinia before I took last year's photo.
As a point of interest: there is also a hybrid, Cstm. Splendens, which is macrocarpum x pileatum. I believe that mine is the species (I got it from someone with English as a 2nd language, but that was my understanding).
Tricho, or someone slightly more expert - opinion?
Cheers - Nancy
