WOOTON AND STANDLEY FLOEA OF NEW MEXICO. 129 



A common and very characteristic plant of tlie mountains of the northern part 

 of the State, often thickly covering large areas of open marshy land. It is some- 

 times eaten by sheep, with fatal results. The common name given in the books is 

 "false hellebore," but in New Mexico it is always known as "skunk cabbage," 

 although it is very unlike the plant which bears that name in tne eastern United 

 States.
