Seeds of the following potatoes, obtained for the use of plant breeders. 

 Tubers of these varieties have been previously introduced ; see S. P. I. Nos. 

 53190 and 53193. 



55557. " Cueruda blanca (white cueruda) potato, 1921 crop, from the 

 hacienda La Rinconada, in the Province of Carchi, where it is culti- 

 vated at altitudes between 11,000 and 12,000 feet. 



" This is the most important commercial potato of Carchi Province. 

 At Ibarra, where it is one of the favorite varieties on the market, 

 it is known as pastuza. It yields heavily, and the whitish brown, 

 somewhat flattened, oval tubers are of good size and quality. The 

 eyes are very shallow and not numerous."

55558. "Cueruda morada (purple cueruda) potato, 1921 crop, from the

 altitudes between 11,000 and 12,000 feet. 



11 Commercially one of the best and most important varieties in 

 northern Ecuador, though it is not quite so extensively grown as 

 cueruda blanca. The tubers are oval, flattened, purple in color, with 

 whitish areas around the shallow eyes ; they possess excellent keeping 

 qualities."
