“ Jazarris is a genus wholly North American, the 
“ tuberous-rooted species of which rank amongst the nu- 
“merous, real or pretended, remedies administered for 
“the bite of the Rattle-snake. To the taste and smell 
“the roots appear impregnated with turpentine, and the 
«¢ plants are for this reason called Pinettes de Prairie by the 
« Canadian boatmen.” Nuttall l. c.
