PLANTS GROWING IN SANDY SOIL. 241 
The generic name of this lovely plant, which means a wolf, 
was bestowed upon it because it has been supposed to devour 
and exhaust the soil. Well, if it does it has the good taste to 
do so in a way highly considerate of its neighbour’s feelings, 
and one that it would be well if all wolves would imitate. By 
spreading itself over sandy, waste places it transforms them 
into an under sky that Venice might envy, and that cheers and 
delights the eye. It has been called sun-dial, as its leaves 
are said to turn to face the sun from morning until evening, 
Old maid’s bonnets is another and rather amusing common 
name of the plant. 
In eastern North America we have but two species, of which 
our plantisthe northern representative. The southern sister 
is called Z. vi/losus. It has oblong simple leaves, in contrast to 
the above, and its podsare beautifully covered with soft, silvery 
hairs. 
The west boasts many varieties of this plant, which all 
closely resemble each other. They are among the peculiarly 
striking and attractive of our wild flowers.
