144 THE STORY OF PLANT LIFE 



The plant is about a foot in height. It flowers 

 rather late, between July and September. It is a 

 herbaceous perennial. 



The floral structure indicates that the plant is 

 adapted to long-lipped insects, none but these being 

 able to reach the honey in the spur, which is not, 

 however, so long as in the Common Toadflax. The 

 conspicuousness of the flowers with the radiating 

 lines or honey-guides, the sweet scent of the flowers, 

 and the honey, render the Creeping Toadflax attrac- 

 tive to insects, so that in most cases it is probable 

 that the flowers are cross-pollinated. 



The capsule contains many seeds, which are wind- 

 dispersed, and the ridged surface facilitates this 

 mode of dispersal. 



Except that the plant is suited to the flower 

 garden there are no properties possessed by it that 

 render it of any economic importance.

Knotted Figv^ort (Scrophularia nodosa). 



From the common Water Betony Knotted Fig- 

 wort differs in the absence of wings to the stem, the 

 more triangular acute leaves, the narrow border to 

 the sepals, and the notched scale. Besides these 

 differences the rootstock is nodose or tuberous (hence 

 nodosa) ; and it was from this characteristic that in a
