43031. IJLiirs DENSA Litv. 



"An elm of remai'kably dense growth, sprouting a little distance above 

 the ground into a number of stems which form an uiiibrellalike head of 

 foliage which is so dense that it seems always twilight, even at bright 

 noon, in an avenue of these trees. This elm apparently loves a climate 

 with long, hot summers and with winters not too cold. It withstands a 

 fair amount of alkali in tlio soil and in the irrigation water. It is of 

 especial value as a shade tree in the hot and di-y interior valleys of 

 California, in Arizona, Texas, and New Mexico." (Frank X. Meyer.)

43032 and 43033. Juglans insularis Griseb. Juglandacefe. 



Cuban walnut. 



From Santiago de las Vegas, Cuba. Presented by Mr. Juan T. Roig, bot- 

 anist, Agricultural Experiment Station. Received July 22, 1916. 



" This interesting Cuban tree has recently been called to the attention of 

 horticulturists by Van Hermann and Roig. It is found in the mountainous sec- 

 tions of the island, sometimes at considerable altitudes. I have seen it in the 

 mountains near Trinidad, on the south coast, at about 2.000 feet, growing among 

 numerous other trees along the banks of small streams. It seems, however, to 

 be comparatively rare, and does not occur in great numbers. It is erect and 

 slender in habit, growing to a height of 40 or more feet, with foliage somewhat 

 finer than Juglans nigra of the United States. The nuts resemlile those of 

 Juglans nigra in size and appearance, though sometimes smaller. The kernels, 

 however, are removed with difficulty, the septje being very thick and woody. 

 In its present wild state the Cuban walnut, as it is calletl, does not seem to be 

 of great horticultural value, but with very little improvement by selection it 

 seems that it might become an excellent nut for tropical regions. It has been 

 suggested that it might serve as a stock for the Persian walnut, making possible 

 the culture of this species in Cuba and other tropical regions where it is not 

 successfully grown. For illustrations of the tree and fruit, see Journal of 

 Heredity, December, 1915." {Wilson Popenoe.)
