Scales are attached to the inner side of the corolla, usually upon the claAV of the petals, as in Buttercups, or within the throat of the corolla tube, as in the Borrageworts, Similar ap- pendages, when enlarged and conspicuoiis, constitute a croicn in Catchfly, Corn-cockle, Narcissus.

Glandular bodies are often found upon the receptacle in the places of missing stamens or carpels, or as abortive organs of some kind. Examples are seen in the Crucifers and Grape. In Grass-Parnassus they are stalked and resemble stamens. 81. The union of organs in some way occurs in almost every flower; and, more perhaps than any other cause, tends to disguise its plan and origin. The separate pieces which stood each as the repi-esentative of a leaf, now, by a gradual fusion, lose themselves in the common mass, Nevertheless, marks of this process are always discernible, either in parts yet remaining free, or in the seams wdiere the edges were conjoined. The floral organs may unite by cohesion or adhesion. 82. Cohesion, when the parts of the same whorl are join
