The other clones of Be Tris 'Ching Hua #3' that I have, have never produced a peloric flower. This clone is a pretty stable peloric.
You are having a problem with the term clone. Be Tris 'Ching Hua #3' is a clone. Everything with that label is vegetatively reproduced from one original plant. They should all be identical. If you have a specimen or mericlone of 'Ching Hua #3' that is peloric, the name should be changed, as it is a mutation, & therefore a new clone. You should label it 'Ching Hua Sport' or something to indicate the difference.
<<Maybe peloria is not so odd, when you consider that Orchids theoretically evolved from an ancestor that had three sepals and three petals.>>
It is not odd at all. You are correct. It is a throwback to a more primitive, radially symmetric flower. It occurs in many other plants, including columbines, snapdragons, and African violets.
