On account of the form of the plant the author recommends the 

 abandonment of the Sulphate of Iron treatment and the use in its 

 place of indirect means. 



Studied the effect of Sulphate of Iron solutions on the germinative 

 power of the cuscuta seed and found that soaking the seed for fifty 

 days in a 20 per cent solution of the salt the germinative power was 

 reduced from 19 per cent to 12 per cent.
