HEXANDRIA, MONOGYNIA. 161 
Co~hosh. 
About two feet high. Berries blue. Said to possess medi- 
cinal virtues. Very rare. I have only found it at the foot of 
a hilly fertile wood, on the west side of the Schuylkill, just 
above the falls, and there it is scarce. Perennial. May.

thickets on rich soil, and in swamps, very common. The bark 
is medicinal. (See Veg. Mat. Med. U. S.) I 2 . June, July.

Resembles the preceding. It is questionable whether this 
is the same plant intended by Pursh, under the name of ambi- 
guus, with which he has made the Cassine Caroliniana of Walt., 
synonymous; but it fits Michaux’s description well. It is also 
the ambiguus of Muhlenberg, according to specimens in liis 
herbarium, which I have lately examined. In a swamp near 
Kaighn’s Point, Jersey. Flowers white. . July.
