648 WorsdelL — The Morphology of the 
pair of foliar organs was reduced to a single anterior one 
(Figs. 28 and 29) ; that this latter was really anterior was 
shown by the fact of its concave surface being directed 
inwards, for I could discern no sign of the apical bud of the 
axis by which to orientate this leaf ; it is interesting that this 
organ had the brown-coloured appearance usually exhibited 
by the ovules alone. 
There came under my notice but a single example in which 
the floral axis simulated that of the primary axis at the apex 
in being swollen and enlarged and in having a foliar organ 
(in the posterior position) more or less fused with it. 
The largest number of members ever seen on a floral axis 
was in a flower possessing two foliar organs and three ovules ; 
it was impossible here to settle the true position of these five 
members, as displacement, arising from the confined and 
limited area of development, had evidently taken place. 
The occurrence of a median pair of foliar organs may be 
regarded as an incipient stage in the transition to the com- 
plete proliferation of the axis of the flower. The next step 
in this direction is indicated by the case shown in Fig. 2 6 , 
where, above the median pair, are two additional pairs of 
foliar organs. Fig. 30 represents a radial section through an 
axillary product at an early stage in its proliferation, showing 
two median leaves with the minute apical bud between them. 
The two lateral ovules are indicated by dotted lines. Here, 
although fewer foliar organs are present, the proliferation is 
really at a more advanced stage than in the last-mentioned 
case, for the axis is considerably developed and a vegetative 
bud already formed at the apex. Complete proliferations are 
shown in Figs. 13, 14, 34. 
Commonly, the axillary bud causes a wide separation of 
the two lateral ovules as it emerges from between them, so 
that each projects considerably beyond the margin of the 
bract on either side. It also not infrequently induces the 
inclination of the primary axis from the vertical plane, so that 
the inflorescence becomes quite curved. 
In one instance in which an axillary bud was present, there
