When has an orchid "bloomed" for naming purposes?

A lot of Dendrobiums do this, especially when newly opened. I have a Pleurothallis that opens from around sunrise to about 8-9 AM depending on temperature, then closes until the next day. It's unusual for a Catt, though. This one is a beauty!

You can check whether or not a cross is registered here: The International Orchid Register / RHS Gardening

The site for registering a cross is here:
Register an orchid hybrid with the RHS / RHS Gardening

The system will tell you if it's already registered. You do have to use the currently-accepted genus names for the parents on both of these links - the RHS sites are not "friendly" with regard to synonyms. Also when you enter the names of the parents, don't enter cultivar names (the part in single quotes)... just the genus and grex (or species) for each parent.
