M. Gris [227] has placed on record some interesting cases of peloria of this kind in _Zingiber zerumbet_; in the more complete forms the androecium or staminal series was composed of six distinct pieces, the three inner of which were fertile, while in the ordinary flower the androecium is composed of two pieces, "a lip" and a fertile stamen.

_Datura fastuosa_, in which the second corolla was partially staminal in its appearance, and bore nearly perfect anthers, in addition to the five ordinary stamens, which were unaltered either in form or position.

Organs originally free and distinct become ultimately combined at the base by the gradual protrusion from the receptacle of a ring or tube under them, as in the stamens of _Leguminosæ_; yet, says Mr. Bentham, no one would propose to describe the staminal tube of monadelphous

This might have been anticipated from the frequent deficiencies in the staminal whorl in these plants under what are considered to be normal conditions.

That the pollen-lobes are not to be taken as halves of a staminal leaf, but rather as specialised portions of it, not necessarily occupying half its surface, is shown also in the case of double-flowered _Malvaceæ_, in which the stamens are frequently partly petal-like, partly divided into numerous separate filaments, each bearing a one -, or it may be even a two-lobed anther.

The petals of cucurbita were observed in one instance united along two of the corollal sinuses to the staminal column, alternating with the smaller stamina; the processes were produced upwards into petaloid appendages.

Again, the existence of adventitious stamens does not necessarily imply the development of organs usually suppressed, inasmuch as they may result from the assumption by the lateral petals of staminal characteristics.

Fig. 156 is a diagram showing the presence of two additional labella within the ordinary one in a species of _Catasetum_, and representing two petaloid stamens, thus evidently completing the outer staminal whorl, of which there is usually but a single representative
