Fig. 6. — The proaxis (d to e) of a branch shoot which developed several 
months earlier from a bud in the upper part of the proaxis (a to b) 
of the primary shoot. The haplocorm of the primary shoot extends 
from 1) to c; that of the lateral shoot has not yet developed. There 
are several buds (h) which did not develop into branches on the pro- 
axis of the primary shoot. No buds are visible in this view of the 
proaxis of the branch, since they are located in a plane at right angles 
to those on the primary shoot, though the upper part (f to g) of a 
small shoot grown from a bud on the branch from the primary shoot 
is shown. The terminal bud of the lateral shoot is shown at e
