 bunt-spores, and is carried on the apex of the growing ergot and 

 surmounted by the withered remains of the style. This is clearly 

 seen in the section of this grain (Fig. 198), in which the dark col- 

 our of the bunt-spores at the apex is contrasted with the lighter-

 of the spikelet are about the size of ordinary wheat-grains, only,

like all bunted grains, they are somewhat shorter and blunter. 

 One of these (Fig. 199, a) is entirely converted into bunt-spores, 

 while the other (6 and c), like the central grain, has an ergot es- 

 tablished in the lower portion, though still young and very small. 



It deserves to be noticed that in both the ergotted grains of 

 this spikelet the early sphacelia state of the ergot is carried up
