stamens, which are produced without anthers, 

 and with their filaments growing together, so 

 as to form a thin membranaceous case for the 

 carpels, which are shown exposed at g. The 

 carpels, when ripe, become follicles. The leaf 

 of the Columbine is bi-ternate ; that is, it is cut 

 into three large divisions, each of which is cut 

 into three smaller ones ; so that it is twice- 

 ternate. The petiole or foot-stalk of the leaf 

 sheaths the stem, as shown at A, where the leaf 

 is represented on a reduced scale to suit the 

 flower.
