Plate VI.— The variety Bluet produced fine capsules (see tag 8 above) 

 when viable pollen was used in cross-pollination. When poor pollen of 

 Rangoon was used there was only complete failure of pod development (see 

 tag No 4). The pollen of Bluet is so poor that it is worthless for any pol- 

 lination. This variety is a good example of a variety that is highly fruitful 

 but pollen sterile.
