STUDY OF ANOMALOUS FLOWERS.

spurred ; in Violet, one petal only ; in Larkspur, two petals and 

 a sepal, the spur of the latter inclosing that of the former. The 

 curved spur of the Jewel- weed belongs to a sepal (27, 28). 



79. Scales are attached to the inner side of the corolla, usually 

 upon the claw of the petals, as in Buttercups, or within the 

 throat of the corolla tube, as in the Borrageworts. Similar ap- 

 pendages, when enlarged and conspicuous, constitute a crown in 

 Catchfly, Corn-cockle, Narcissus. See also the staminal crown 

 or corona of the Silk-grass (Asclepias, fig. 532).

 upper one spurred; c, the corolla of four petals, here united into one and produced into a spur. 27, Flower 

 of Impatiens fulva (Touch-me-not). 28, Displaying s, , s, y, the four sepals, y being saccate and spurred; 

 p, p, the two petals, both double, preserving the symmetry. 



80. 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 representative 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 where the edges were conjoined. The 

 floral organs may unite by cohesion or adhesion. 



82. Cohesion, when the parts of the same whorl are joined
