Neof. Hybrid vs Ascofinetia,etc

[Shoreguy]

First off, I hope this thread doesn't deteriorate into a discussion of the Vanda designation.

Is there a formal or informal rule or understanding naming convention to describe how such plants are to be referred to or is it somewhat subjective?

That is, naming a hybrid plant with Neofinetia ancestry with a name such as Neofinetia Yubae, or an intergeneric name such as Ascofinetia Cherry Blossum.

Sometimes the decision is forced by not knowing the complete ancestry in which case the name must be of the form Neofinetia XXXXXXXXX, but if known what if any are the rules, formal or informal?

If there are rules, formal or informal, what are they?
