Peloric form of labiata.

Not peloric, but interesting markings certainly, in a lovely example of C. labiata.

I think, peloric, but pelorism involves not inner petals in this case, but all of three sepals. Dorsal sepal is not normal, but same as inner petals, lower sepals are similar to labellum. It had been described yet as "Odilon".
Have a look at the second pic, you can see pelorism of sepals.
Some phal folks call this "semi-pleoric." Appropriate here too?

Peloric is a term often used for orchids, but not always used correctly. It had a technical meaning in floral morphology long before it was broadly applied to orchids. That definition of peloria could be stated as: Changes in a zygomorphic (bilateral symmetry) flower that make it more actinomorphic (radial symmetry). The Wikipedia article on floral symmetry illustrates this well. The term does not apply to changes in floral morphology that do not fit this pattern.
In the most typical case in orchids the petals take on some characteristics of the lip, and that fits the definition perfectly.
In this case the opposite is true - the flower has actually become less radially symmetrical - the opposite of a peloric change. The dorsal and lateral sepals are normally similar, but here the dorsal sepal is distinct and more like the petals, and the lateral sepals have become more like mirror images of each other as they took on some characteristics of the lip. With the previously similar sepals differentiating, the flower has less radial symmetry.

Thank you for the clarification, Kirk.
Very good explanation. Thank-you!

I asked a brasilian expert, he said it is so called "petaloid" veriety.

Since all 3 sepals take on characteristics of petals (the lip being a modified petal) that is a very apt description.
I've seen pictures of much more dramatic examples of lateral sepals picking up lip characteristics, in both Catts and Cyms. It is subtle here by comparison. And there are orchids where this pattern is typical morphology - Phal stuartiana for example.
It would be interesting to see 'Odilon' crossed with a splash petal Catt - perhaps see some lip characteristics on all petals and sepals.
