Cattleya Dinard was registered in 1930 by Charlesworth as (Saint Gothard x Dinah). I can’t access RHS records for awards for any of these classic heirloom plants.
Dinard has 6 species ancestors (warscewiczii 25%, warneri 25%, trianae 12.5%, tenebrosa 12.5%, dowiana 12.5%, and schilleriana 12.5%). There have been three AOS-awarded Dinard cultivars: ‘Kinn’ (HCC, 1999), ‘Blue Heaven’ (AM, 2001), and ‘Veronica’ (FCC, 2016). ‘Blue Heaven’ has been mericloned and is popular. I don’t think I have ever seen ‘Veronica’ available to purchase so it is probably closely held in limited collections. The AOS award pictures, description, and measurements of 'Veronica' are stunning.
Cattleya Arthos was also registered by Charlesworth in 1942 as (Dinard x trianae). I don’t know if it was ever RHS awarded, but it doesn’t appear to have been used in breeding. There aren’t any AOS awards for Arthos and Orchids Limited suspected that it hadn’t been remade in decades, so they remade the cross. Arthos is comprised of the same 6 species as Dinard, but of course with a much heavier dose of trianae (trianae 56.25%, warneri 12.5%, warscewiczii 12.5%, schilleriana 6.25%, tenebrosa 6.25%, dowiana 6.25%). Here is a picture of the current blooming of my plant, made against a black background under an LED panel delivering light rated at 3500 K (a little more red than blue).
The Orchids Limited Arthos cross used a high quality trianae coerulea, hoping to maintain coerulea coloration and maybe even improve size or shape. Some of the plants from the cross achieved this. I think the following link should take you to a short video that Jerry Fischer made about the cross with some example blooming plants.
