quality which experience has discovered to be useful in pulmon-

Cult. Al the species of Pulmondria are very pretty plants 
when in blossom; and being. early flowerers they are rather 
desirable for borders. They are of the most easy culture, and 
will grow in any common garden soil, and are readily increased 
by division. Most of the species grow well under the drip of 
trees, and all do best in shady situations.
