in the entire inflorescence is considerably higher for the plants in the 
large pots, i. e., 9.4 as compared with only 3.3 for the smaller plants. 
The average number of branches in the terminal whorl is somewhat 
higher for the larger plants, 3.3 for the plants in the 8-inch pots, and 
2.8 for the plants in the 4-inch pots. With respect to the position of 
the first bald sucker, columns (4) and (5) bring out the same relations 
that were shown in the preceding test. Although an average of 6 
lateral flower branches was produced by the larger plants, the average 
had been reduced to one lateral branch in the plants grown in 4-inch 
pots. 
Owing to the fact that stunting has been extreme in this test, the 
data in column (4) are particularly significant. For the larger plants 
the average number of leaves above the cotyledons, not including the 
first bald sucker, is 26.4 as compared with the much higher average 
of 32 for the ten plants in the 4-inch pots. In many of these plants 
it is shown that there was complete suppression of all the lateral 
branches of the inflorescence. 
A comparison of the data for the two experiments, as shown in 
Tables I and II, brings out the fact that the average number of nodes 
produced by the plants, exclusive of the terminal whorl of branches, 
has remained unchanged under all conditions of growth: 
If the average number of nodes, including the terminal whorl, is 
considered, it is indicated that the plants in the second experiment 
have produced somewhat fewer nodes than those in the first experi- 
ment: 
1st experiment 
Plants moist soil, 32.4 nodes 
" dry " 32.9 
2d experiment 
8-inch pots, 32.4 
4 " " 32.8 
1st experiment 
Plants in moist soil 36.6 nodes 
" " dry " 36.1 " 
< I 
8-inch pots 35.8 
4 " " 35-6 
2d experiment 
" 4 
Since it has been shown that the average number of nodes exclusive 
of the terminal whorl has been unchanged, it is evident that the above 
reduction has taken place in the branches of the terminal whorl.
