The weight of stem tissue reached a maximum at 75 days and thereafter changed but little; the weight of the leaf tissue diminished during the development of the inflorescence. The precise magnitude of these later changes is in some doubt because of the sampling error involved in the selection of the older plants. The water content of the plants of Sample II of each collection is plotted in Figure 2. The curves are less smooth than those in Figure 1 because.
