Low herbs from deep-seated corm-like tubers: leaves 3 in a whorl, broad 

 and netted-veined: flower single, of 3 colored petals and 3 green sepals, the 

 latter persistent until the angled, many-seeded berry ripens: stigmas 3, 

 often sessile. Plants of earliest spring, growing in rich woods. 



a. Flower sessile in the leaf-whorl. 

 T. sessile, Linn. Flowers dull purple, the parts narrow, pointed, and 

 nearly erect: leaves sessile, ovate^ often blotched with purple. Pa.,W. and S. 



aa. Flower stalked in the leaf-whorl.
