The European congeners of this plant, (E.Jis- 

 tulosa and (E. crocata, are undoubtedly pois- 

 onous. Our species is eagerly eaten by cattle, 

 a fact that becomes very evident in a swamp 

 near the Presidio, where it grows in company 

 with Cicuta Californica, the latter not being 

 touched by the animals when (Enantlie is eaten 

 up to the roots. It would be desirable to in- 

 vestigate the properties of the species.
