The peculiar behaviour of the second clusters of No. 3 and 8 is apparently due to cold. The distinction between two clusters is easily determined by the formation of the scale leaves at the end of each cluster. The formation of the first cluster of No. 9 was thus spread out over one whole month, with a break in the middle.

In both years the position of the asterisk, under the first, second

or third letter of the month indicates that the cluster unfolded in the

beginning, middle or end of the month respectively.

It would be seen that the number of the clusters formed by the

ten plants during the two years were as follows :—

It is clear that the largest and probably the oldest plant formed only one cluster each year. The rest formed one, two or three, and all of these formed more than one in at least one of the two years. From these observations and others given further on in the paper made on much older trees which were growing on land in the garden, it will be seen that in young plants more than one cluster is usually pro- duced each year, while older plants produce only one cluster every
