Cattleya Louis Chaton
 

Here is an Award of Quality (AQ/AOS) photo of Cattleya Louis Chaton (percivaliana x trianae) at Mid-Atlantic judging last month. David Off made the cross with C. percivaliana ‘Summit’ and C. trianae ‘Cashen’s’. An Award of Quality goes to the hybridizer. It is awarded to a hybrid that shows improvement over the parents with 12 plants being exhibited and at least one receiving an AOS Award.

Here is one I thought was especially good that I took home:

The flowers seem awfully closed...improvement on both parents? Do you think so?

Very nice!

Beautiful! I'm always surprised to see new primaries from parents discovered long ago.

Thanks for the comments!

William - I agree about the closed shape.
The judges awarded two that I didn’t think were so great. The one I picked has overlapping petals, which on subsequent bloomings may be larger and flatter in my conditions.

Over the years, through careful back-crossing and line breeding, not to mention the potential manipulation and creation/selection of improved cultivars - some 4N - the parents may be far better than those used when the original crosses were made.

Judges here - it appears the plant in the original post by Bayard was awarded under the wrong name. What happens next to correct this?

I went to look up the origins of the names. It's confusing. I started at Orchid Roots, because it's easier to use than the RHS registered hybrids page. But I went to the RHS for confirmation.

Orchid Roots says there were two different crosses registered as C. Louis Chaton in 1898. One is lawrenceana x trianae, Maron 1898, which Orchid Roots says should be named C. Cecilia, Ingram 1895. The other is percivaliana x trianae, Maron 1898, which Orchid Roots says should be named C. Adela, Veitch 1898.

I went to the RHS to double check this. The RHS shows Louis Chaton as lawrenceana x trianae, Maron 1898, but considers it a synonym of C. Cecilia, Ingram 1895, which was also called C. Cecilae, Ingram 1895, and C. Elata, Ingram 1897. So here Orchid Roots agrees with the RHS.

The RHS shows percivaliana x trianae as C. Adela, Veitch 1868. So Orchid Roots also agrees here with the RHS.
