dren nod to her as they pass by. She is one of the best be- 
loved of our waste-ground flora. 
The double variety, Plate CLVI, suggests the bloom of a cul- 
tivated flower; and this is not to be wondered at, as it was at 
one time much planted in gardens, It is rather more common

plants are spreading very rapidly. Their juice, when mixed 
with water, forms a lather. This fact is well known.

trimorphous,—that is, they have stamens and pistils of two 
different lengths. ‘The short pistils must receive the pollen 
from the short stamens in another blossom ; and the long pistils, 
the pollen from the long stamens. 
At night the plant folds together its leaves and sleeps. O.
