Catasetinae - perfect flowers, hermaphroditic flowers

[nancy]

Greetings -
I've looked for this information all over the 'net without finding it...okay, Clowesia were detached from Catasetum because they have 'perfect' flowers, rather than male, female or hermaphrodite as Catasetum do.
So - what's the difference in flowers between perfect and hermaphrodite? Visually, can you tell?
And since I'm asking the weird stuff, what's say I have a Clowesia x Catasetum (which I do!), will the flowers be male, female, perfect, hermaphrodite, or some 5th sex? (Now we're talking!).
This is partly idle curiosity, but also a genuine serious question. This whole group of genera is really lacking in information!
Thanks - Nancy
