Rhizoma horizontal, throwing off numerous long and slender bright yellow fibres of an in- 

 tensely bitter taste. Leaves evergreen, on long petioles, very smooth and shining, strongly 

 veined ; leaflets about an inch long. Scape slender, but somewhat rigid and wiry, 3-6 

 inches long. Flowers about two-thirds of an inch in diameter. Sepals 5-7 oblong, obtuse, 

 white, sometimes purplish underneath. Petals much shorter than the sepals, yellow at the 

 base. Carpels acuminate with the persistent curved style. Seeds oblong, smooth and shining ; 

 raphe indistinct. 



Common in sphagnous swamps, and in damp shady woods around the roots of trees ; flower- 

 ing in May, and ripening its fruit about the end of June. The root is a pure bitter, like that of 

 Quassia, without any astringency. It is extensively employed as a tonic, both in domestic 

 practice, and as an ordinary article of the materia medica.
