in ordinary cases effectually suppress any extension of the 
growing point. It is, however, to be remarked that in Pinus 
Pinea the cone is often not quite symmetrical ; there is a sort 
of apical appendix, as if terminal growth were not relinquished 
without a struggle. 
I have already noticed that the cone now described is below 
the normal size. It may be supposed that the food-supply 
directed towards it was in excess of its needs. The growing 
point was therefore started into activity. That this was not, 
however, accomplished without a struggle is proved by the 
deep constriction between the shoot and the cone. The 
passive tension of the apex of the cone prevented any increase 
in the diameter of the shoot till it was entirely free from it. 
The age at which the specimen came into my hands had 
obliterated any trace of external morphological continuity 
between its two parts. But it seems impossible to shut one’s 
eyes to the fact that the fascicles of leaves in the upper part 
must correspond to the carpophylls or seminiferous leaves in 
the lower. 
One or two other points remain to be mentioned. Why 
the cone was shed, seeing that it was actively vigorous, is 
difficult even to conjecture. When first found the shoot was 
six inches long ; it is now sixteen : it therefore grew at least 
ten inches after separation from the parent tree. The cone is 
probably figured in about its normal position : the strong 
curvature of the shoot is no doubt due to geotropism. 
The shoot was entirely dependent on the cone for its supply 
of both constructive material and water. It is a striking 
illustration of the power possessed by rapidly-growing tissues 
of not merely diverting nutriment from others which are less 
active, but of actually robbing them. But in the absence of 
roots the supply was bound sooner or later to come to an end. 
Probably the actual cause of death was, notwithstanding the 
pains of the Comte de Paris, the failure of a water supply to 
maintain the transpiration current.
