CE. fistulosa (Fig. 26) is also aquatic. It has a 

 mixture of slender and fleshy roots. The leaves 

 are much arrested with few, narrow segments and 

 hollow petioles (see the figure). 



The sepals of the flower are unusually large 

 (see figure) ; as in most 

 umbellifers they are quite 

 rudimentary. 



This species is poison- 

 ous ; but it is only ex- 

 ceptionally that animals 

 have eaten it spontan- 

 eously.^ 



Though the above 

 species are very danger- 

 ous, yet one, CE. pinipinel- 

 loideSy a rare plant in 

 England but commoner 

 abroad, has roots which 

 are eaten. They are full 



of starchy matter with pig^^e. CEnanthe fistulosa ; Common 

 the flavour of filberts, and Water-Dropwort. 



were formerly sold at Angers and other continental 

 markets. It is said, however, that when wild they 

 are not so harmless as when cultivated. 



^ Dr. Tanner recommends for poisoning by species of 

 CEnanthe or Water-Dropwort., emetics, castor-oil, and stimu- 

 lants. Cold affusions will often be useful, more especially if 

 there be much stupor.
