plants of this order contain a milky juice. The 
stamens of the flowers are 8 in number, 
generally divided into 2 equal bundles, and 
therefore diadelphous. 
The Fumitory family, Fumariace&, though 
not important plants, are very interesting from 
the singular conformation of their flowers. We 
have only two genera of this order, Corydalis 
and Fumaria. Corydalis lutea is naturalized 
on old walls, and seems almost to spring from 
the very stone, displaying its yellow flowers. 
C. claviculata, found in bushy places in hilly 
districts, has very small flowers, yellowish 
white, and its stems climb several feet; it is
