Rhizoma thick and fleshy, its upper portion tunicated, its lower 

 half solid and sending forth a multitude of large whitish roots. 

 Stem from 3 to 5 feet high, roundish, solid, striated and pubescent, 

 throughout the greater part of its length closely invested with the 

 sheathing bases of the leaves. Lower leaves large, from a foot to a 

 foot long, oval, acuminate, pubescent, strongly plaited and nerved; the 

 lower part -of their edges meeting round the stem; upper leaves 

 gradually narrower ; the uppermost, or bracts, linear-lanceolate. Flowers 

 numerous, in compound racemes axillary from the upper leaves, and 

 terminal; the whole forming a sort of panicle. Peduncles roundish, 

 downy. Bracts boat-shaped, acuminate, downy. Pedicels many times 

 shorter than the bracts. Perianth divided into 6 green, oval, acute, 

 nerved segments, of which the alternate ones are longest ; all the seg- 

 ments contracted at base into a sort of claw with a thickened or carti- 

 laginous edge. Stamens 6 with recurved filaments and roundish, 2- 

 lobed anthers. Carpels 3, cohering, with acute recurved styles as long 

 as the stamens. A part of the flowers are barren and have only the 

 rudiments of styles, so that the plant is strictly polygamous. The seed 

 vessel consists of 3 capsules united together, separating at top and 

 opening on their inner side. Seeds flat, winged, imbricated. The 

 roots are an acrid emetic and powerful stimulant followed by sedative 

 effects. In all respects it closely resembles Veratrum album in its 

 properties.
