"In one of the oldest towns of the Republic of Panama, about 8 
miles from the Canal, I found 3 trees of the blood-red grapefruit. I 
was told by one of the oldest inhabitants that these were the original 
trees, all the others in the vicinity being seedlings from them. These 
3 trees have never been cared for, but were simply planted and allowed 
to grow up in the jungle, without pruning, spraying, or fertilizing. 
They appear to be at least 40 years old, and are about 50 feet high." 
juglans INSULARIS ( Juglandaceae ) . 58810. Cuban walnut From Santi- 
ago de las Vegas, Cuba. Seeds presented by Prof. Gonzalo M. Fortun, 
director, Estacion Experimental Agronomica. 
"In the summer of 1915 I traveled in Cuba, accompanied by Prof. 
Fortun. Our principal object was the study of Cuban mangos, but we 
made observations on other Cuban plants of economic interest, among 
them the native walnut, Juglans insularis. On the southern coast of the 
island, near Trinidad, we saw this tree in the wild, and obtained nuts 
which Prof. Fortun planted at Santiago de las Vegas. The trees which 
sprung from them have now come into bearing, and Prof. Fortun has for- 
warded this shipment of seeds. 
"In the Journal of Heredity for December, 1915, an article entitled 
'Plant Breeding in Cuba 1 , was published by F. S. Earle and myself. 
Illustrations of the Cuban walnut accompanied this article, in which 
appeared the following note: 
"'Another native plant of possible economic value has recently 
been brought to the attention of horticulturists by H. A. Van Hermann 
and Dr. Juan T. Roig. This is the Cuban walnut, Juglans insularis, a tree 
occurring in the mountains of the island and producing nuts which com- 
pare favorably in size with the northern black walnut. The kernels 
are difficult to remove from the shell, however, and the partitions are 
thick. The tree is not at all common, and horticulturally speaking it 
is practically unknown, yet it might be of great value as a stock on 
which to graft some of the cultivated walnuts, or through selection it 
might be improved considerably. There are very few first-class nuts 
which succeed in Cuba, or in the Tropics generally, and the addition 
of a walnut to those already cultivated would be a distinct advance. 1 
"Since the above lines were written, little has been done to furth- 
er the horticultural development of this interesting tree. From the 
seeds now sent by Prof. Fortun we hope "to grow plants for distribution 
to tropical horticulturists and plant breeders, whose active interest 
in the Cuban walnut would probably have been aroused earlier, had such 
material been available to them." (Wilson Popenoe.)
