It generally affects the style and stigma only, as happens normally in _Petalostylis_, _Iris_, &c., but this is by no means always necessarily the case. In some of the cultivated varieties of _Anemone_ and _Ranunculus_ all the parts of the flower remain in their normal state, except the pistils, which latter assume a petaloid appearance. Many of the double flowers owe their peculiar appearance to the combination of the following appearances--a petal-like form of the stamens, increase in the number of these organs and similar changes affecting the pistils, and is applied to several distinct conditions. If in any given flower all the stamens and all the pistils become wholly petaloid, no pollen is formed, and of course no seeds can be produced, but this very rarely happens, as usually some pollen is produced, and some ovules capable of being fertilised are developed.
