 southeastern states, but anthers blunt : lvs. coarsely

viviparum, Greene, is a very large and handsome, 

 purple-fld. species ; subalpine on Mt. Rainier. In the 

 axils of the lvs., along the thick rootstock, bulblets are 

 produced, by which it propagates. Its capsule opens by 

 a lid, as in many far-western species, e. L. Greene.
