 or less narrowed at the base, twice the length of the stamens. — S'.ems robust, leafy : leaves ovate

Root thick and fleshy ; the lower part giving off numerous whitish fleshy fibres. Stem 

 2-4 feet high, very leafy, stout, pubescent. Leaves 6-10 inches long and 3-5 inches 

 wide, pubescent, strongly plaited and nerved, acuminate, clasping ; the upper ones gradually 

 diminishing in size till they become lanceolate bracts. Panicle 8-12 inches long ; the 

 branches simple or somewhat compound. Pedicels about 3 lines long. Flowers yellowish 

 green. Leaflets of the perianth denticulate on ths thickened margin. Stamens rather longer 

 in the perfect than in the abortive flowers ; the filaments recurved. Styles about 2 lines long, 

 recurved. Capsule nearly an inch long, consisting of 3 follicular carpels united on the inner 

 side, and finally separating about half way down. Seeds 10- 18 in each carpel, oblong 

 (including the broad wing), pale, acute at the apex ; the nucleus linear-oblong. Embryo oval, 

 in fleshy albumen. 



Swamps : common. Fl. May. Fr. July. This plant is nearly allied to the V. album of 

 Europe, and possesses similar active qualities. It is popular throughout the country as an 

 external remedy for cutaneous affections ; but it is dangerous when swallowed, even in small 

 quantities. Like many other plants of this natural order, it contains the very poisonous 

 principle called veratrine.
