petalody

As the morphological difference between the organs is one of position merely, there is little objection to be raised to this course, the less so as the term petalody merely conveys an idea of resemblance and not of absolute identity.

To a certain extent the change in question is the same as that spoken of under the head of petalody (see p. 283), but there are cases in which, while the ordinary situation and form are those of leaves, the coloration is that of the petals.

The bearings of these and other similar malformations on the morphology of the anther are alluded to under the head of petalody of the anther.

This change results from an imperfect petalody of the anther; the two wings on each side of the central vascular cord represent the front and back walls of an anther lobe, or rather of that portion of the anther which, under ordinary circumstances, produces pollen.

In instances where the organs are formed successively in spiral order, we meet with such changes as median prolification, petalody, and phyllody.

_Arbutus Unedo_, &c. The change is associated with petalody of the stamens and pistils.

Morren [454] describes some flowers of _Orchis morio_ in which there were three sepals, three petals, and within the latter two other ternary series of petals; this would seem to be a case of petalody of all six stamens.

In these flowers, owing to the petalody of the stamens and pistils, one or both, an impression of exaggerated number is produced, which is by no means necessarily a true one.
