SYMMETRY OF THE CENTROSPERM X. 281 
last six measurements on the main axis originally were 38:5, 21, 6, 8'5, 4,4°5. The 
resultant curve differed so entirely from those of specimens previously measured that I 
examined the axis in this region. I found that the measurement 6 was from a leaf 
which had no axillary bud to the insertion of a branch which apparently had no 
subtending leaf. Thus the branch was raised above the true leaf-axil, and the true 
measurement of the internode was 6+8°5=14°5. A similar raising of the branch 
above the axil of the next higher leaf had also occurred, so that the true dis- 
placement-measure was 4+4°5=8°5. These corrections regularized the subcurves 
and incidentally demonstrated the existence of “fusions” between branches and main 
axis.

Two specimens (Plants 8 and 10) were measured by Mr. A. Deane. The branches 
emitted at the cotyledonary node are termed cotyledonary branches; the branch in the 
axil of the first foliage-leaf is Branch I and so forth.
