Stanhopea tigrina (peloric)

[RobS]

Peloria in orchids occurs when the petals take on the color and/or the shape of the lip, and may be found anywhere between two extremes. In Broughtonia sanguinea 'Aquinii' there is a slight coloration found at the tips of the petals similar to the color in the lip, while in Cymbidium hoosai 'Butterfly Lip' the petals may have the full appearance of the structure of the lip. The presence of peloria is genetic, but expression of peloria may be influenced by environmental changes or by being stressed. These are not always stable, and the plant may flower normally on the next inflorescence.

I think this definition is valid. Highligted the important part. Partially peloric flowers are as much a deformation as complete peloric flowers.

Conclusion these flowers are peloric.
