As is the case with many families the frost-weed raises two 
sets of children. The first, which unfold in July, are large, 
solitary and open in the sunshine only. ‘The next day they 
droop their petals and die. They resemble closely an evening 
primrose. Perhaps the plant finds them too luxurious and deli-

whimsical in shape burst open the bark and rear themselves on 
high. These are supposed to be the sap of the plant, which ac- 
cumulates moisture and then freezes.

persistently eaten too freely, it sends them to their everlasting
