ment of an axillary bud. In the accompanying diagram (diagram 1), 
A represents the basal portion of the dead stem of 1905; B, the aerial 
shoot of 1906; L*, opposite leaves of the shoot A, and in the axil of 
the one of these (to the right) a small bud (6), while in the axil of 
the other the floral shoot (C) is developed. Shoot C has also a pair of 
| opposite, scale-like leaves (Z?), both 
subtending buds, but of different 
size, the one behind C being the 
larger (B). This large bud (or 
u young shoot) will grow into an 
aerial stem in 1907, while the two 
smaller buds (0) will remain dor- 
mant. The diagram is of a speci- 
DraGRaM I men in its fifth year, and not yet 
blooming. 
If we examine the apical portion of a mature specimen with fruits 
(early in October), the position of the buds is the same as described 
above, but the number of leaves may be larger. In diagram 2 the 
dead stem A has one pair of opposite leaves (L'), the one to the right 
subtending a bud (bd), while 
the one to the left subtends 
a floral shoot (C). This floral 
oot bears three pairs of 
leaves with one large (B) 
and three smaller buds (0); 
B corresponds with B in the 
diagram described above, and 
is situated behind C. But B 
is here separ.ted from C by 
two pairs of leaves, and thus ‘ns 
is situated somewhat lower DIAGRAM 2 
than in the other specimen, 
but occupies the same position behind the floral shoot C. The large 
bud in the axil of L* (to the right of A), as stated in the preceding, 
is so far advanced that the internodes are quite distinct, and this 
bud sometimes develops into an aerial shoot when C becomes 
injured. Otherwise the rhizome does not branch so as to develop
