This is a paragraph of a very interesting read on pelorics and taken from -

"... there are those who feel that peloria is not a good quality to look for in an orchid flower. Some feel that peloric flowers are deformities, and that "peloric orchids that display a complete inflorescence of deformed flowers should automatically be disqualified from further consideration'' in AOS judging, some also feel that the flowers of Dendrobium Classic Gem are no longer "true" orchids, and so will not grow or judge them. But some of these same people feel that splashed-petal cattleyas are now accepted as normal, and can be attractive. While not taking a stand on their merits, the American Orchid Society refers to peloric flowers as deformed, and this term may be misapplied. Deformity in the dictionary is: a physical blemish or distortion, disfigurement. Examples of deformity are: a split dorsal or ventral in Paphiopedilums, a flower that possesses two columns, or a flower where floral parts may be physically missing. Peloric flowers are mutations that have occurred, whether naturally or induced, in orchid flowers, and mutations are a part of evolution. AOS judging criteria for quality is based on recognizing superiority and improvement of a given type of flower over previously awarded flowers, or similar lines. The AOS Handbook on Judging and Exhibition states: "new lines of breeding, including new shapes,...should be considered but should not be awarded unless the new line has superior characteristics and quality.'' Peloric flowers can be considered a new shape or line of breeding, but whether they are a superior form, or possess good quality is a controversy." ...
