" The fniit is broadly elliptic, oval, or nearly round ; weight 

 about 10 ounces; lenjitli about 3J incbes, greatest breadtb about 

 3^ inches; l)ase rounded to bluntly pointed, witli tlie stem inserted 

 slightly to one side of the center; apex very slightly and obliquely 

 flattened ; surface smooth, somewhat glossy, dark purplish maroon 

 to purple, with large, pale maroon-colored dots; skin of average 

 thickness for a large-fruited ^Mexican avocado ; flesh ricli cream 

 colored, with fiber markings and even a few tough fibers in 

 some specimens, while others have none at all ; flavor rich and 

 pleasant; quality good; seed .small, round-ovo!d, tight in the seed 

 cavity, with both seed coats surrounding closely the slightly 

 rough cotyledons. Principal season of ripening at San Vincente 

 from February to Api-il. 



"Numerous specimens of this variety were examine<l; some of 

 them were of excellent quality, while others had objectionable 

 fiber in them. The difference may have been due to variation in 

 the stage of maturity. If the variety, when gx-own in the United 

 States, produces fruits which, at the proper stage of ripeness, are 

 quite free from fiber, it should prove to be a genuine acquisition. 

 The flavor is rich and the flesh very abundant." 



53185." (No. 577. Hacienda San Vicente, Province of Carchi. Feb- 

 ruary 17. 1921.) Budwood of avocado No. 51. Carchi. The 

 parent tree is growing in one of the huertas of the Hacienda 

 San Vicente, about half a mile north of the house. This variety, 

 except for its color, might be called a Mexican Trapp. It has 

 the form of the latter, and it also has a seed somewhat larger 

 than the ideal ; but if the size of the fruit increases when the 

 variety is given the advantage of good culture in the United 

 States, it may prove to be a valuable sort. The fruit is oblate, 

 about 8 ounces in weight, purple when ripe, with yellow flesh 

 of good flavor and quality. The seed is sometimes loose in the 

 cavity. 



" Formal description : Parent tree 30 feet high, the trunk 18 

 inches thick at the base and branching at 8 feet above the 

 gi'ound. The crown is round, dense, with the foliage of peculiar 

 wrinkled appearance. The leaves when crushed have a pro- 

 nounced aniselike odor. 



" The fruit is oblate, sometimes oblique ; weight about 8 ounces, 

 length about 2f inches ; base rounde^l to .slightly flattenefl, the 

 stem inserted obliquely ; apex conspicuously and usually some- 

 what obliquely flattened ; surface smooth, dull purple in the 

 fully ripe fruit, with large dots of lighter purple ; skin of about 

 average thickness for a large-fruited Mexican avocado ; flesh 

 yellow, tinged with pale green close to the skin, nearly free 

 from fiber markings, the flavor rich and pleasant ; quality good ; 

 seed large, oblate, tight in the cavity, with both seed coats 

 adhering closely to the nearly smooth cotyledons ; occasionally 

 the seed coats separate. Principal ripening season at San A'icente 

 from January to March."

"(No. .oS4a. Hacienda La Esperanza. near El Angel. Province of 

 Carchi, Ecuador. February 15. 1921.) Seeds of Mora de Rocota. A. 

 rare berry from an altitude of 12,000 feet. It is nearly round, i-ed, 

 1^ inches in diameter, and of good quality. The fruits are mucb 

 like those of the Colombian berr.v (RuhKn unicrocdrijii.i) in geniM-al 

 appearance, but smaller and better in quality. This .species seems 

 to be the same as the Huagra-mora, from the slopes of the Volcano 

 Tungurahua at an altitude of about 9.000 feet, and tbe mora, which 

 grows in the Cordillera de Zamora. in Loja Province. The plant is not 

 a large grower. It forms clumps about 5 feet high, or sometimes scram- 

 bles over other plants, its canes reaching to about 8 feet in length. The
