SABBATIA ANGULARIS. 
American Centaury. 
staal 
— 
PLATE LVI. 
Unper the name of Chironia angularis, this 
plant has been familiar to physicians in the 
United States as a native bitter. As it wants the 
most distinguishing characters of Chironia, while 
it has others of a very different kind, particularly 
in the anthers and stigma; I have followed the 
example of Pursh and others in referring it to the 
genus Sabbatia of Adanson. 
This genus is characterised by a persistent 
calyx from five to twelve parted ; a corolla from 
five to twelve parted ; anthers finally revolute ; 
stigma two parted, spiral; capsule one celled. 
The Sabbatia angularis differs from the rest of 
the genus in being erect, the leaves clasping, 
peduncles elongated and corymbose, segments of 
the calyx lanceolate, half as long as the corolla ; 
stem square and winged.
