The dominant plant was Potamogeton amplifolius Tuckerm. The large leaves of this plant were green in spring but became white with deposits of calcium carbonate as the bicarbonate equilibrium shifted towards carbonate during the summer. The deposits weighed down the plant and caused a more prostrate appearance than usual. 2. Kidder Lake. Figures So few species occurred in this lake that it was possible to count the exact number of individual plants in many locations. But there is much shallow shoreline where plants might reasonably be expected to grow. In a survey conducted in June, only one plant of Nuphar variegatum En- gelm. was found in the lake and it occurred near the inlet. By the end of August this plant was well established although it had not flowered. At this time two more Nuphar plants had become estab- lished some 20 feet from the first. Several Potamogeton amplifolius plants were observed near the inlet end of the lake and small numbers.
