This upright, delicate stalk of tiny white flowers suggests 
‘ittle to us of the terrible, brilliantly-coloured monster with 
flaming eyes and upraised fangs for which it has been named. 
But it springs from the same root as its curious leaves, and they 
are supposed to have a peculiar efficacy in curing the bites of 
rattlesnakes, |The Indians are credited with placing great 
faith in them. It may be that they have a soothing effect on

and we would sadly miss it from the May woods if some day it 
should learn the trick of wandering and stray from us far away
