In double flowers of _Primula sinensis_ it frequently happens that the capsule is either partially leafy or partly petal-like; in either case the fruit is open at the extremity, and often destitute of the style and stigma. It is, however, doubtful if the ovules can be fertilised in these flowers. The following list comprises the names of those genera in which this change has been most frequently observed, independently of corresponding alterations in the stamens, but it is more usual for both sets of organs to be similarly affected. *Ranunculus! *Anemone! Nigella. *Papaver! *Dianthus! Saponaria! Viola! Camellia! Alcea. Hibiscus! Amygdalus! Lonicera! Scabiosa. AEschynanthus! Primula! =Petalody of the ovules.=--The principal changes which occur in the ovule have already been alluded to at pp. 262-272; it may here be stated, however, that the ovules are occasionally represented by small stalked petal-like structures. This happens with especial frequency among _Cruciferae_.[313] =Petalody of the accessory organs.=--A petaloid condition of the disc, of the scales, or other excrescences from the axis or from the lateral portions of the flower, is of frequent occurrence, though it is but rarely that the change is of any great importance in a morphological point of view. C. Morren has given the name adenopetaly to a case wherein one of the glands at the base of the petals in _Lopezia_ was replaced by a petal.[314] A similar change may be seen in the double Oleander. =Staminody of the bracts.=--An instance of this has been already alluded to in _Abies excelsa_, as observed by Prof. Dickson, and in which some of the bracts were seen assuming the form and characteristic of the stamens see _ante_: p. 192. Signor Licopoli met with a similar substitution of anthers for bracts in _Melianthus major_.[315] =Staminody of the sepals and petals.=--In the first named this is of very rare occurrence. M. Gris has recorded an instance in _Philadelphus speciosus_[316] which appears to be the only case on record. The corresponding change in the case of the petals is far more common. De Candolle cites in illustration of this occurrence flowers of the common haricot, in which the alae and carina of the corolla were thus changed.[317] There is in cultivation a form of _Saxifraga granulata_ wherein the petals are replaced by stamens, so that there are fifteen stamens. A similar change has been observed in _Capsella bursa-pastoris_.
