 Southwest United States. Frequently cultivated in greenhouses. 



Poisonous prol>erties. John Smith, in his Domestic botany, says, with 

 reference to its poisonous properties : 



It grows abundantly in the valley of the Jordan, and when in flower is very beantiful. Tlie 

 whole of the plant is poisonous, and it is recorded that soldiers in Spain were poisoned through 

 their meat being roasted on spits made of the peeled stem. 



Prof. Chesnut states that stock are occasionally poisoned by eating the 

 leaves, as the plant grows wild in northern Mexico and is abundant in the 

 Southwest. The oleander is a heart stimulant acting like digitalis. Dr. S. 

 Wateff recently reported a case in which gastro-enteritis occurred; nausea, 

 vomiting and irritation were prominent symptoms. He also reports the odor 

 of the flower as poisonous.
