ing shed on the stigma, and the growth is at first 

 comparatively rapid. Its course is readily traced in 

 the conductive tissue of the style, vrhich is greatly 

 disorganized from the large number of tubes usually 

 present. The course is between the cells rather than 

 through them. By the time that winter sots in the live 

 part of one or more tubes is to be i'ound in the neigh- 

 borhood of the base of the funiculus (Fig. 18), There 

 are usually several live tubes at varying heights in 

 the style at this time, (Figs. 26,27) and evidence of 

 many more which have been stranded above. The unpro- 

 t'^cted tip of the style is dead and withered, while 

 that part which is clothed with hairs is alive. It is 

 in this protected part of the carpels that the pollen 

 tubes hibex-nate. Soon after pollination the flower 

 head twists on its stalk so as to invert each blossom. 

 The inverted calyx then very effectually protects the
