SUMMARY. 



Chrosperma musccetoxicum has been recognized as poisonous, but 

 has not previously been reported as a stock-poisoning plant. 



The plant has been known locally, in parts of North Carolina, as 

 dangerous to cattle and sheep. 



Experimental work has confirmed the opinion of its poisonous 

 properties, and has shown that it is an extremely toxic plant. 



Inasmuch as the plant occurs from Long Island to Florida and 

 as far west as Arkansas, it seems probable that it may cause losses 

 of stock in many places besides those reported.
