either develop at once after formation (text-fig. 1, points b to j except с) or 
remain practically permanently dormant (point e). The position of the 
branch so developed may be sympodial (text-fig. 1, branch g, 4, and у), either 
accidentally or of necessity, or it may be lateral. When such a branch is 
developed, the direction of the main axis, if it persists and does not turn into 
an inflorescence or any semblance of it, is one of the following. It is either 
in a line with its basal internode (text-fig. 1, point b) or it is quite turned out 
of its course by the daughter-axis ; or, lastly and most frequently, both the 
main and the daughter axes stand more or less equally out of the axial line 
formed by the prolongation of their common base. 
The lateral buds in the axil of a sheath have always a period of rest 
between their formation and sprouting. Besides, all such buds on a branch 
or even on a succession of branches develop simultaneously. 
Appearance at various stages of growth—The terminal bud of the leader 
always appears growing, its growth, as already stated, being continuous. 
The young parts are protected by the stipules of that leaf the blade of which 
is last exposed (РІ. 17. fig. 1). 
Regarding the terminal bud of the developed lateral branches, its appear- 
ance varies with its structure and stages of growth. For a time the stipules 
ot the blade last unfolded protect it as in the last case (Pl. 17. fig. 2). Soon, 
however, the bud outgrows the accommodation within the stipules. At this 
stage it is found enveloped by the sheathing leaf, when such is present ; this 
sheath, we have seen, succeeds a normal leaf at an extremely short distance. 
In this condition (Pl. 17. fig. 2 and tips of branches in text-fig. 1, p. 259) it 
rests until the last expanded leaf develops to almost its full size, when the 
sheath bursts open to let out the next normal leaf. Ву this arrangement the 
young inflorescence is exposed at a very early stage; for, being outside 
the stipules of the leaf inserted at its own level (РІ. 17. fig. 2), from the 
moment the sheath of the preceding node prepares to drop off there is 
nothing to cover it. The inflorescence provides itself against this defect by 
early lignification of its parts. Regarding the axillary buds, all are protected 
by a sheath, since the first leaf of a branch is always a sheath, as already 
stated (Pl. 17. fig. 6 for the resting condition). The axillary buds on the 
leader, that sprout immediately after their formation, show a gradation of 
size as we traverse a succession of internodes (Pl. 17. fig. 1: at the last point 
it is too small to be seen from the side view). No such gradation is to be 
seen in the case of the buds in the axil of the sheath on the lateral branches ; 
they sprout almost simultaneously. 
Leaves. 
There are two things to be considered here: the leaf proper and the 
structure forming a mere sheath, but equivalent toa leaf. The terms “leaf” 
and ** sheath " will be respectively used for these structures.
