Palmandan!
You can find the AHS database entries either directly from the AHS site (scroll down the left navigation bar on the home page for the database and then enter your search word/s) and also from the ATP database which includes links from ATP entries to the AHS entries.
For 'Tetrina's Daughter' the page is here:

The other one I mentioned, 'Magic Dawn', a more obvious "imposter" (some consider the bicolor often sold under that name to be 'Howdy' - the AHS registered plant is a "rose pink self" not a purple/yellow bicolor as pictured), is here:

@floota, thanks Julie. I'd made further enquiries and consequently both Debbie and Janice were informed two weeks ago, probably too soon for any corrections to have been made. I assume there'd need to be a committee discussion about 'Tetrina's Daughter' because the colour is right and the question is about form, although 'Magic Dawn' is obviously the wrong picture.
