How do you read these labels?
 

I'm looking at some Catleya on a vendor's website, and some names are rather complex. Normally I don't have trouble understanding what the cross is, but how do you read something like this? Are there parentheses missing or is there a specific rule/convention to indicate the order of crossing?

Cat. Chuzca Real x schilleriana x (Green Emerald x Brabantiae)
and
Cat. (Sophia Martin x Thospol Spots) x aclandiae x Peckhavien

For instance should the second one be understood as
A) Cat. (Sophia Martin x Thospol Spots) x (aclandiae x Peckhavien)

B) Cat. (Sophia Martin x Thospol Spots) x aclandiae, with the resulting offspring then crossed to Catt. Peckhavien?

C) something else entirely?

I think that even with a convention, there's going to be uncertainty about whether or not somebody applied a convention.

But when there's a cross between A and B ............ A is the plant that developed the pod .... so A x B has 'A' being the pod plant.

With something like A x B x (C x D), it's hard to say what happened there ------- as it is sort of open ended. Ambiguous.

But even A x B can have issues if somebody lost the actual details about the order, or which one was the pod parent.

Definitely parenthesis's missing.

I looked up Chuzca Real. It is C. tigrina x C. Pechaviensis, so it is a valid name by itself. The logical assumption, would be something like this:

Cat. ([Chuzca Real x schilleriana] x [Green Emerald x Brabantiae])

But, you need to speak with the seller to confirm this. In these cases, I challenge the seller and tell them that I won't buy till they clarify.[COLOR="Silver"]

With the names as you wrote them it is not possible to fugure out what is meant. The seller may not have any more information, and needs to query up the chain of custody.
