In the first and second sections of Table VIII the most striking 
fact is the wide variation of the individual plants in their ability to 
form seed when the flower is self-pollinated or pollinated from 
another flower of the same plant. There is clearly a great difference 
between individuals in this respect. In the matter of averages, 513 
self-pollinated flowers produced 165 pods, or 32.1 per cent, while 
437 flowers, each pollinated from another flower on the same plant, 
produced 134 pods, or 30.6 per cent. On the same 12 plants, 446 
‘flowers, each cross-pollinated from anotuer plant of the same variety, 
produced 206 pods, or 46.1 per cent. 
From 114 pods of the self-pollinated flowers 158 seeds were pro- 
duced, an average of 1.4 seeds per pod; 118 pods from the flowers pol- 
linated from another flower on the same plant contained 238 seeds, 
an average of 2.02 seeds per pod; while 160 pods from the cross- 
pollinated flowers contained 382 seeds, or 2.38 seeds per pod. 
It would appear, therefore, that cross-pollination is more potent 
than self-pollination, while pollination from another flower on the
