Peloric: This is the abnormal production, by mutation, of a symmetrical flower in a species that normally bears asymmetrical flowers. Orchids, with their large and different lips, form a good example of a flower that is not normally symmetrical and most Corydalis are also asymmetrical. A peloric orchid, would be expected to have three lips in place of the normal one, if the two other true petals mutate into a lip.
As peloric forms are often more attractive than their unmutated forms, when stable, they have frequently been preserved and vegetatively propagated in horticulture.
The term was first used by Charles Darwin.
