1. (E. CALIFOENICA Watson. Common. 

 Aquatic. Summer. 



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

 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 Cieuta Californica, the latter not being- 

 touched by the animals when (Enanthe is eaten 

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

 vestigate the properties of the species.
