PLANT MATERIAL INTRODUCED

 Chenopodiaceae. 



quinoa Willd. 

 Quinoa. 



From Lima, Peru. Seeds presented by A. H. 

 Rosenfeld. Received March 24, 1926. 



The native inhabitants of the highlands of west- 

 ern South America cultivate this plant for the sake 

 of the seeds, which are creamy white and about 

 three times as large as those of the common North 

 American weed known as "goosefoot (Cheno- 

 podium album). In pre-Columbian times this 

 native cereal ranked in importance with the potato 

 and corn. The plant is an abundant yielder and 

 is harvested in early summer. The seeds are 

 washed for about 24 hours in order to remove the 

 bitter flavor, and the washed seeds are boiled 

 and eaten in the same manner as rice.
