MODIFICATIONS OF THE STIGMA. 291 
term lobe is usually applied when the divisions are thick, as in 
the Lily (jig. 646) and Melon (fig. 647); or when these are 
flattened and somewhat strap-shaped, as in the Composite (fig. 
648), the stigma is fissured or cleft ; or when flattened into

plates or bands they are termed lamellx, as in the Bignonia (fig.

which the pistil is composed; and if the latter organ is many-

divisions of the stigma. Thus the five-cleft stigma of some 
Campanulas indicates that there are five cells to the ovary, and
