The Ipomaa purga supplies the jalap of the medical 

 prescriptions. Though a native of Mexico, the plant is 

 freely grown out of doors, both on the continent of Europe 

 and in the garden of the Society of Apothecaries in 

 England. Like the small bindweed, its peduncles are two-

 corolla is crimson in colour. The root of the plant is the 

 part of officinal value. 



Scammony, another drug in the Mater -ia Medica, is a 

 gummy or resinous exudation from the roots of the 

 Convolvulus scammonia, a species having its flowers of a 

 very delicate tint of sulphur yellow. Several other species 

 yield useful products.
