52722. "(No. 555. Ambato, Ecuador. January 12, 1921.) Calvache 

 potato, grown near Ambato. This is a productive and late-matur- 

 ing variety, grown mainly at the lower altitudes. The tubers are 

 elliptic-obovate and compressed to long and slender in form, of 

 medium size, with a light rose-pink surface marked with very few 

 and shallow eyes. The flesh is white and of good quality." 



52723. "(No. 551. Ambato, Ecuador. January 12, 1921.) Donvinga 

 potato, grown near Ambato. This variety, which is cultivated at 

 the lower altitudes of this region, is moderately productive. The 

 tubers are medium sized, roundish oval, light rose colored, with 

 white flesh of good quality. One of the most important commercial 

 varieties." 



52724. "(No. 552. Ambato, Ecuador. January 12, 1921.) Huagra- 

 singa potato, grown near Ambato. This is a late-maturing variety, 

 with tubers irregularly round, pale yellow brown, with violet- 

 colored areas around the rather deep eyes. The flesh is white, 

 of fair quality. It is slightly resistant to late-blight and is grown 

 at both high and low altitudes." 



^ 52725. "(No. 549. Ambato, Ecuador. January 12, 1921.) Inglesa 



potato, grown near Ambato. This moderately productive, late- 

 maturing variety has round, good-sized tubers of dark violet, with 

 moderately numerous and deep eyes. The flesh is white and of 

 good quality. This has proved at Ambato to be the most resistant 

 to late-blight of all the varieties tested." 



52726. "(No. 554. Ambato, Ecuador. January 12, 1921.) Leona 

 potato, grown near Ambato. A late-maturing, productive variety 

 which is most successful at the higher altitudes. The tubers are 

 round, medium to large, brown, the eyes few and not very deep. 

 The flesh is white, and superior in quality to that of all others 

 cultivated in the Ambato region. The keeping qualities of the 

 variety are excellent." 



52727. "(No. 550. Ambato, Ecuador, January 12, 1921.) Leona 

 Pazmina potato, grown near Ambato. This late-maturing and 

 moderately productive potato yields tubers of oval to round 

 form, medium size, dark-red color, with moderately few and not 

 very deep eyes. The flesh is white and of excellent quality. The 

 plant, which grows best at high altitudes, is moderately resist- 

 ant to late-blight. The variety keeps better than most of the 

 others known at Ambato." 



52728. "(No. 556. Ambato, Ecuador. January 12, 1921.) Manzana 

 potato, grown near Ambato. This productive and late-matur- 

 ing variety, cultivated mainly at the lower altitudes of the Ambato 

 region, produces tubers of irregularly round form, medium size, 

 with a rose-pink surface and rather numerous and deep eyes 

 marked with yellow. The flesh is white and of good quality. 

 The plant is not resistant to late-blight." 



52729. " (No. 548. Ambato, Ecuador. January 12, 1921.) Talla 

 potato, grown near Ambato. This is one of the largest potatoes 

 cultivated in Ecuador. The plant is very productive, and the 

 tubers, which mature rather late in the season, are elongated.
