POLYGAMIA, SUPERFLUA. 109 
Elecampane. 
: This well-known plant, is becoming naturalized in this vici- 
nity, as it has long been in different parts of the United States. 
I have found it in many places in Jersey, Pennsylvania, Mary- 
land, and Virginia, with every appearance of Dairies a native 
plant. On the borders of fields, near the Buck Inn, on the 
Lancaster road. InJersey near Woodbury, and on the Botanic- 
garden-ground of the University of Pennsylvania; rare. Pos- 
sesses medicinal properties and has been much esteemed by 
physicians. (See Woodville.) At present its use is confined 
to domestic practice.—Plant three or four feet high, leaves 
very large and rough. Flowers also large and globose. Pe- 
rennial, July, August.
