 (Ipomoea purga Hayne.) 



"A Mexican climbing plant, Avith salver-shaped purplish flowers, which fur- 

 nishes the true jalap tubers of commerce. These are roundish, of variable size, 

 the largest being about as large as an orange, and of a dark color. They owe 

 their well-known purgative properties to their resinous ingredients, and hence 

 worm-eaten tubers are more valued than sound ones, as the insects eat the 

 farinaceous and woody portions of the tuber and leave the resin." (M. T.
