What is the correct way to write this cross?

Sweet Almond Mint x ((Darla Anita x Tropical Hot Flash) x Happy Happy)

Is this anywhere close?

An uppercase 'X' between the pod parent and the pollen parent helps divide it between the (maternal X paternal) sides of the equation. Seedlings as parents can make them really hard to sort out sometimes if that upper case 'X' isn't there.

It depends on how the cross was made. The pedigree above describes this scenario; Pollen from Tropical Hot Flash was used on Darla Anita, producing a plant, which was pollinated with pollen from Happy Happy. Pollen from the resulting plant was used on Sweet Almond Mint.

If the proper convention of Pod x Pollen is used, and all parentheticals are closed and correctly nested, the use of an uppercase X doesn't seem necessary. I've also seen square brackets used occasionally in pedigrees, but I'm not aware of their formal significance.

Ken, you are correct about the generations.
I'm confused as to where to place the double or perhaps triple parentheses for
multiple generations.

In writing, brackets and braces as well as parentheses are used, but the AHS rules indicate
only the use of parentheses if I understand the rules correctly.

Since you recognized the multiple generation chain clearly, perhaps the above is
okay.
Sorry, I wasn't very clear with the initial question.

I usually start with the "first" or "oldest" cross in the parentage and work outward from there. Just remember that the parentheses need to be balanced, or used in pairs, so if you are writing out a pedigree and add a closing parenthesis, make sure you add an opening one to the other side of that particular sub-cross.

It's right as rain. An alternate solution that seems to have been successfully employed by some hybridizers is to name and register every 'keeper' seedling, reducing the complexity of subsequent pedigrees.

I would write the cross this way, maybe I'm doing it wrong???

Sweet Almond Mint X (Darla Anita x Tropical Hot Flash) X Happy Happy

The AHS registration instructions include these examples, if that helps (pod parent first of course):

"One Generation Example: (Shockwave × Sunny Magic)
Multi-Generation Example: ((Chateau Blanc × Pale Blush) × sdlg)
Multi-Generation Example: (Pale Blush × (Kali × (sdlg × Polly Mayo)))

NOTE: Only Registered names may be used. The abbreviation for seedling “sdlg” or the word “unknown” will be used for all non- registered names."

I could write the cross as (Sweet Almond Mint x sdlg), but that
shows very little information for what genetics may be present in
the plant.

Thanks so much for all the assistance from each of you.
Most appreciated.
