By the French it is known as ‘‘Cigué vireuse,” ‘‘Cigué tachetée” 
being applied to Conium. 
SPECIES OF CICUTA REPORTED AS POISONOUS. 
The following species of Cicuta have been reported as poisonous: 
C. maculata, bulbifera, vagans, bolanderi, occidentalis, californica, curtisii, 
douglas, purpurea, tenurfolia, and virosa. In some cases this belief. 
is supported by strong experimental evidence. This evidence is | 
especially strong in regard to maculata, vagans, occidentalis, califor- 
mica, and vwrosa. ‘There is every reason to believe that all species of 
Cicuta are poisonous, and possibly all equally so. | 
LOCALITIES WHERE CICUTA POISONING HAS OCCURRED. 
The number of reported cases of poisoning by Cicuta in Europe is 
very large, by far the greater number having occurred in Germany. 
Fic. 1.—Map of the United States, showing the distribution of recorded cases of poisoning by 
Cicuta. Dots indicate the locations of poisoning of human beings, while crosses show the 
. locations of cattle poisening. 
In figure 1 the recorded cases of poisoning in the United States 
have been plotted, dots indicating the places where members of the 
human family have been poisoned, while crosses show the localities 
of cattle poisoning. This chart has been compiled from publications 
and from definite records in the.Office of Poisonous Plants of the 
United States Department of Agriculture. The first published ac- 
count was by Stockbridge, 1814. Figure 1 by no means represents the 
entire number of cases. The compilation of this chart brought out 
in a surprising manner how imperfectly such cases have been put on
