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 in the market, it i.s known as Pa^^tuza. It 

 yieUls heavily, and the whiti.'^h brown, somewhat nattene<l. oval 

 tubers are of good size and quality. The eyes arc very shallow 

 and not numerous." 



53194. "(No. 596. Hacienda La Kinconada, Province of C'archi, 

 Ecuador. February IG, 1921.) Tubers of Leche, cultivated at 

 altitudes of 11,000 to 12,000 feet. This is a good variety, of some 

 commercial importance, especially in the vicinity of Ibarra. 

 It yields heavily, and the round, whitish brown, rather large 

 tubers are of good quality. They have, however, rather deep 

 eyes." 



53195. "(No. .^)97. Ibarra. Ecuador. February 12, 1921.) Tubers of 

 Yu)igara, from the Hacienda La Rinconada, in the Province of 

 Carchi, where it is cultivated at altitudes of 10,000 to 12,000 feet. 

 This is probably the same as the Yungara of Ambato, but is not 

 as important commercially in northern Ecuador as it is in the 

 latter region. This productive and late-maturing variety yields 

 oblong, medium-sized tubers, light rose colored with yellow areas 

 around the few and not very deep eyes. The flesh is white and 

 of good quality ; the plant is not resistant to late-blight."

 IV. 



53196. "(No. 598. Ibarra, Ecuador. February 12, 1921.) Pastnzn, 

 from the Hacienda La Rinconada, in the Province of Carchi, where 

 it is cultivated at altitudes of 11,000 and 12,000 feet ; it is one of 

 the favorite varieties in the market at Ibarra. This is i)rnbably 

 the same variety as Cnertida hlanca (white Cueruda). This is 

 the most important commercial potato of Carchi Province. 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." 



53197. "(No. .593. Hacienda La Rinconada, Province of Carchi, 

 Ecuador. February 16, 1921.) Amarga, cultivated in the Province 

 of Carchi, at altitudes of 11,000 and 12,000 feet. This is not an 

 important or well-known variety. Its tubers are of irregular 

 shape, rather small, pale rose in color, with deep eyes." 



33198. JuGLANS sp. Juglandacese. Walnut. 



"(No. 599a. Ibarra, Ecuador.) The tocte (black walnut) of northern 

 Ecuador. Seeds obtained in the market of Ibarra. There are probably 

 two species of .luglans in Ecuador which go under this name: one of 

 them is J. peruviana, the other as yet undescribed. Both are found in 

 the highlands, between altitudes of 6,000 and 10,000 feet; one or the 

 other is abundant, in nearly every town of the Sierra. The tree is 

 sometimes called nogal, as well as tocte; the fruit is always known by 

 the latter name. 



"Luis Cordero (Enumeracion Botanica) says of this tree in the Prov- 

 ince of Azuay: 'It is most useful, since it furnishes, aside from its 

 grateful fruit and its fine, solid, and beautiful wood, a tonic of prob- 

 able eflScacy, obtained fi-om boiling the leaves.' The plant is much used 

 by the Indians of Imbabura Province in the preparation of dyes. 



" The tocte is abundant at Ambato. It can scarcely be termed a cul- 

 tivated species in this region, since it is not commoidy planted ; but trees 

 which spring up around cultivated fields and in dooryards are allowed 

 to grow unmolested, and the fruit is utilized in a small way. The plant 

 strongly resembles Jnnhms nigra, but the foliage is perhaps larger. 

 The nuts are an inch and a half in diameter, with a very thick, bony 

 shell deeply corrugated on the surface and a kernel of mild, pleasant 

 flavor. Recently the species has been utilized in Ambato as a stock 

 plant on which to graft Juglnns rcgia.
