A Living Refrigerator 
In this direct color photograph print it will be seen that 
the stems and leaves are covered with formations which appear 
to be tiny icicles. The plant is known as the ice plant, and the 
icicles, in fact, are stored up moisture which it saves up against 
the heat of the sun. The need for this extra moisture 
is not apparent where this plant now grows, and 
it is reasoned, therefore, that the plant 
has been stranded, at some time or 
another in its history, in some 
unusually hot, dry climate.
