The term peloria was originally given by Linné to a malformation of
On the other hand, were the ligulate florets to be all replaced by tubular ones, the term peloria would be more strictly applicable.
This was considered so marvellous a circumstance that the term peloria, from the Greek [Greek: pelôr], a prodigy, was applied to it. [
Possibly these several differences may be connected with the different flow of nutriment towards the central and external flowers: we know, at least, that with irregular flowers, those nearest to the axis are most subject to peloria, that is to become abnormally symmetrical.
These flowers are ordinarily described as belonging to the anomaly  known as "peloria," or regular form of a normally symmetric type; they are large and irregular on the stems and the vigorous branches but slender and quinate on the weaker twigs.
This kind of peloria may for distinction sake be called regular or congenital peloria (see chapter on that subject); but where a flower becomes regular by the increase in number of its irregular portions, as in the _Linaria_ already alluded to, where not only one petal is spurred, but all five of them are furnished with such appendages, and which are the result of an irregular development of those organs, the peloria is evidently not congenital, but occurs at a more or less advanced stage of development.
= -- Various deviations from the ordinary type of orchid structure have been already alluded to under the head of displacement, fusion, peloria, substitution, &c., but the alterations presented by the androecium in this family are so important in reference to what is considered its natural conformation, that it seems desirable, in this place, to enter upon the teratological appearances presented by the androecium in this order, in somewhat greater detail than usual.
To this latter form of peloria it is proposed to give the distinctive epithet of irregular.
Amongst orchids, where the pedicel of the flower or the ovary is normally twisted, so that the labellum occupies the anterior or inferior part of the flower, it frequently happens, in cases of peloria and other changes, that the primitive position is retained, the twist does not take place, and so with other resupinate flowers.
The occurrence both of regular and irregular peloria on the same plant has frequently been observed in _Linaria_.
