34 SEEDS AND PLANTS IMPOETED. 



43483 and 43484— Continued. 



43484. Attat.f.a sp. Phoeuicacese. Corozo palm. 

 " Coro.zo. Very abundant, but little exploited because of the difficulty 



of brealiing the shell." 



"An undescribed species, closely related to the Cohune, or Corozo 

 palm (Attaica cohime). of the Caribbean coast region of Central America ; 

 it differs from the Cohune palm in the smaller and more rounded fruits 

 and the thinner and more brittle shell of the seed. The seed contains a 

 single kernel, smaller than that of the Cohune. The kernels contain a 

 high percentage of oil, said to be the equal of coconut oil and suitable 

 for the manufacture of similar products. The palm is said to grow in 

 great abundance in the vicinity of Mazatlan, Sinaloa, Mexico. The kernels 

 are exported in considerable quantities from Mazatlan to the Pacific 

 ports of the United States for oil extraction." (C. B. Doyle.) 



43485 to 43487. 



From Guatemala. Cuttings collected by Mr. Wilson Popenoe, Agricultural 

 Explorer for the Department of Agriculture. Received November 2, 

 1916. Quoted notes by Mr. Popenoe. 



43485. Annona cherimola INIill. Annonacese. Cherimoya. 

 "(No. 49. Duenas. Departamento de Sacaterpequez, October IS. 1916.) 



Bud wood of an unusually choice variety of cherimoya, or anona as it is 

 called here, from a garden in the village of Duenas, about 10 kilometers 

 from Antigua. The cherimoya is very common in this region, which 

 lies at an elevation of about 5,200 feet. There is great variation in the 

 shape and character of the fruit, and the trees seem- to vary in productive- 

 ness. Most of them bear very few fruits. The tree from which this 

 bud wood was taken has a trunk about a foot in diameter, but at a 

 distance of 10 feet from the ground the top has been removed, probably 

 two years ago, and the sprouts which are to form the new top are now 

 about 6 feet long. There are a good number of these sprouts and they 

 are now in bearing, producing more fruit than is usually borne by the 

 , ordinary tree of mature size, although the latter would have a crown 

 10 to 20 feet broad and a vastly greater amount of fruiting wood. 

 Whether the productiveness of this variety is an inherent characteristic 

 or whether it has been induced by topping the tree, I am unable to 

 determine, but on the chance that it may be inherently a heavy bearer I 

 have secured bud wood for propagation and trial in Florida, and more 

 especially in southern California, where cherimoya culture could un- 

 doubtedly be developed into a horticultural industry if prolific and 

 otherwise desirable varieties were obtainable. The fruit of this variety 

 is of excellent size and appearance. It varies from 3 to 7 inches in length 

 and from about 6 ounces to nearly 3 pounds in weight. In form it is 

 uniformly conical, blunt at the apex. The surface is nearly smooth, with 

 the carpellary areas indicated by raised lines. The color is light green. 

 The fruit begins to ripen about the first of October, but the season is not 

 at its height until after the end of the year. Many of the fruits are 

 attacked by an insect which burrows in the seeds. Its presence can be 

 detected by small round holes on the surface of the fruit." 



43486 and 43487. Peksea Americana Mill. Lauracese. Avocado. 



(P. gratissima Gaertn. f.)
